A large number of examples. In colour, and especially in the sculpture of the 

 pygidium, agrees with Burmeister's description of C. testacea ; but Burmeister places 

 C. testacea in his subsection "body elongate cylindrical," whereas our species is quite 

 remarkably short and rotundate-ovate. His description of the claw-joint of the 

 anterior male tarsi, " massige verdickt," is also inapplicable, as our species has the 

 claw-joint very unusually large and thickened, with the larger claw of extraordinary 

 length and stoutness. The closely allied C. minuta (found also on the Amazons) is a 

 smaller insect, 7 millim., and has a coarsely punctured shining pygidium. A Chontales 

 specimen is figured. 



IV. Clypeus latus, antice sinuatus ; mentum ante palpos angustum, suhrotwidatum, 

 antiee medio plerumque anguste incisum.

Distinguished by the elytra having together eight black spots arranged in a circle, of 

 which the two nearest the scutellum are the largest. The black spots on the thorax 

 are more variable in form and number, and in many examples disappear without 

 corresponding diminution of the elytral spots. The largest examples and those with the 

 largest black spots occur in Mexico. In specimens from Guatemala and further south 

 the spots are generally smaller and the general form of the insect more slender and paler 

 in colour, but large-spotted examples, though rarer, occur in Guatemala, as small-spotted 

 ones do in Mexico. The female is distinguished by the lateral margin being abruptly 

 produced into a small lobe a little behind the middle, the surface of the elytron 

 between the lobe and the slightly elevated callus being depressed. Found commonly 

 by Mr. Champion in the spathes of large Arums at Zapote. A specimen from Orizaba 

 is figured. 



25. Cyclocephala amblyopsis. (Tab. xvill. fig. 5, <s .) 



C. lucidce proximo affinis, sed minor et angustior, flavo-testacea, nitida, vertiee cum fronte thoracis maculis 

 duabus elytrorumqne macula utrinque prope scutellum (rarissime macula parva discoidali versus apicem)
