4 RHYNCHOPHORA. 
British Honpuras* (H. A. Wickham, Mus. Brit.); Nicaragua, Chontales (Belt, 
Janson).—CoLoMBIA ; VENEZUELA; TrinipaD (Mus. Brit.) ; Eouapor. 
This very variable species (of which I have seen about 100 examples) is a common 
insect in Mexico, ranging as far north as Chihuahua and extending southward to 
Trinidad and Ecuador. Schénherr, in his later work 2, selected the name C. punctulatus 
for it, sinking C. meawicanus and C. pustulatus as varieties, and to these must also be 
added C. nodieri and other Mexican forms. They are all connected by intermediate 
examples and may be roughly defined thus :— 
a. The prothoracic spots usually more or less coalescent; the elytra nigro-bifasciate, the tubercles large and 
somewhat closely placed. (Fig. 2.) 
Cratosomus punctulatus, Gyll. loc. cit. 
Cratosomus glandulosus, Chevr. in litt. 
Mexico, widely distributed and apparently the commonest form there; Colombia. 
3. The prothorax with ten or twelve separate spots; the elytra at most irregularly nigro-fasciate at the 
middle, the tubercles large. (Fig. 3.) 
Cratosomus punctulatus, var. 8. mexicanus, Schonh. loc. cit. 
Cratosomus subfasciatus, Chevr. in litt. 
Mexico (Vera Cruz, Guerrero, Oaxaca), British Honduras, Nicaragua, Trinidad, 
Venezuela, Ecuador. 
y. The prothorax usually more rounded at the sides, and often with a few tubercles on the disc, the spots 
more or less confluent ; the elytra nigro-bifasciate, with the whitish vestiture reduced to a network of 
transverse confluent spots, the tubercles large. (Fig. 4.) 
Cratosomus punctulatus, var. y. pustulatus, Schonh. loc. cit. 
Cratosomus sallei and rotundicolits, Chevr. in litt. 
Mexico—Vera Cruz, Morelos, Guerrero, Oaxaca. 
6. The spots on the prothorax not quite confluent, separated by a network of whitish lines; the elytra as 
in y. (Fig. 5.) 
Cratosomus nodieri, Gyll., Schonh. 
Cratosomus mestus, Jekel, in litt. 
Mexico—between Acapulco and Oaxaca. 
e. The prothorax with from 10-12 spots, the basal two sometimes united, as well as the three on the 
flanks ; the elytra as in a, but with broader black fascie. (Fig. 6.) 
Cratosomus - -maculatus, Chevr. in litt. 
Mexico—Durango, Vera Cruz, Oaxaca (three examples) f. 
g. The prothoracic spots confluent; the elytra as in e. 
Cratosomus corectus, Chevr. in litt. 
Mexico—Oaxaca (two examples). 
* This specimen is labelled Temash R., Brit. Honduras ; perhaps in mistake for Temax, Yucatan ? 
y+ There is an example of this form in the British Museum labelled “Brazil,” but there must be some 
mistake about this locality.
