"General: Body 1.8 times as long as wide; dorsal surfaces rather shiny, elytra a little less shiny than pronotum; dorsum "without pubescence, most of ventral surface with short, sparse pubescence. Head: Front and clypeus ivory yellow, an inverted V from vertex to antennal insertions, lateral margin of clypeus and labrum orange; front and clypeus with rather small, sparse punctures; clypeus broad, apex somewhat wider than base. Antennae two-thirds length of body in female, brown throughout. Pronotum: Orange with ivory yellow as follows (light markings not sharply delimited); in two oblique basal spots; at lateral margin (this narrower posteriorly, abruptly wider anteriorly); narrowly at anterior margin. Orange areas speckled with minute darker spots, densest laterally at base, nearly absent medially at base except on median line, median line anteriorly without spots. Punctation dual, small punctures minute, larger punctures quite small. Elytra: Background color ivory yellow, dark markings brown. Dark markings of each elytron interconnected, confined largely to area bounded by suture to sixth stria at side and from basal limit of punctures to apical limit of third to sixth intervals; markings not attaining base, lateral margin, or apex; with yellow at base near scutellum, at middle of side, in a common spot on second and third intervals, and in apical spots on third, fourth, and fifth intervals. Each elytron with seven rows of fine, rather dense punctures and a series behind humerus, finer apically as usual; fifth row confused before apex, sixth row irregular behind humerus; inner and outer rows distinct at apex, more or less clearly meeting. Ventral surface: Ventral surface and legs orange; with ivory yellow on prosternum, mesosternum (plus side pieces), basal median part of first abdominal segment, and at sides of first to fifth abdominal segments; ivory yellow broad on fifth segment. Anterior margin of prosternum in female broadly, not strongly, lobed. Pygidium ivory yellow, median line and base narrowly brown, surface rather coarsely punctate. Fifth abdominal segment m female with a large, oval, deep depression at center. Length: 4.2 mm" (White, 1968: 46-7).
"Cryptocephalus contextus is similar to cowaniae; the two are separable on the basis of the dark elytral markings. In cowaniae, these attain the sides of the elytra just behind the middle and before the apex; in contextus, they do not attain the sides of the elytra. The specific name (meaning connected) refers to the fact that the dark elytral markings are interconnected.C. contextus is also similar to the Central American species patheticus Suffrian. The basic elytral pattern is the same; however, the body size and extent of the dark markings separate the two. C. contextus is 4.2 mm. long, and two specimens of patheticus in the USNM collection are 2.8 mm. and 3.0 mm. long. In the two specimens of patheticus, the dark elytral markings attain the sides of the elytra; in the single specimen ofcontextus, they do not. In addition, this species is quite similar to the illustration and description of C. decemplagiatus Jacoby in the Biologia Centrali-Americana (1889, p. 111). I have seen no individuals of the decemplagiatus so have been unable to make a direct comparison. One apparent difference is that the pronotum of decemplagiatus is described as predominantly brown; that of contextus is orange" (White, 1968).
