"Pronotum: Dull orange to red, margins usually yellow or at least lighter, not sharply delimited; punctation usually dual, smaller punctures very sparse to nearly absent, larger punctures minute. Elytra: Light creamy yellow to orange, striae and dark markings red to (usually) dark red. Dark markings as follows: on base of second interval curving to apex of sutural stria; on apex of second stria; at base, middle, and apex of fourth stria; behind base, behind middle, and on apex of sixth stria; on humerus; behind base at middle of seventh stria; above markings reduced to (rarely) nearly absent or (more often) transversely joined and forming three undulating bands. With seven rows of punctures and a short series behind humerus, sixth stria interrupted and joining fifth, latter sometimes also interrupted at junction with sixth; punctures as large, dense as usual, finer apically, intervals rather to quite convex; inner and outer rows distinct at apex and clearly meeting. Prosternum: Anterior margin in male somewhat produced into a broad lobe, anterior margin in female feebly produced. Length: 3.8 to 5.0 mm" (White, 1968: 55).
"This species is similar to but evidently distinct from a single specimen from the Monros collection determined as C. austerus Suffrian taken at Orizaba, Mexico. In the latter individual, the elytral surface is rather depressed by two narrow, transverse, dark bands, and the striae are somewhat distorted. This condition does not occur in fulguratus. Two additional specimens in the USNM collection (one from Mexico, the other from Guatemala) determined as C. rimosus Suffrian differ from fulguratus by the above characters and apparently are not distinguishable from austerus" (White, 1968).
