184 RHYNCHOPHORA. 
small scales, which are very variable in colour—blue (type), green, cupreous, rosy, cinereous, or whitish, 
and sometimes scintillate with metallic golden reflections, or differently coloured along the suture and 
margin or disc of the elytra, or on the under surface,—and also set with long, fine, erect, pallid hairs, 
those on the elytra arranged in a single row down each interstice, the suture set with longer setiform 
hairs towards the apex in @. Head and rostrum together about as long as the prothorax, the rostrum 
canaliculate and broadly depressed down the middle ; joints 1 and 2 of the funiculus subequal in length. 
Elytra rather finely seriate-punctate, the interstices each with from four to six rows of scales and with 
a scattered irregular series of very small, bare, smooth spots. Legs densely squamose and pilose ; inter- 
mediate tibiz unguiculate in the J. 
Length 7-10, breadth 24-4 millim. (¢ @.)

This variable insect is generally placed as a form of H. dejeani in collections, from 
which it differs in the smaller scales on the upper surface and the more abundant fine 
scattered setosity. In most of the specimens the scales are uniformly green or 
cupreo-cinereous ; but in the short series from Chiapas nearly all the colour-varieties 
are to be found, including several with intermixed scintillating metallic scales or the 
elytra faintly maculate. I have not seen an example from Arizona. ‘The equally 
variable S.-American H. gemmifer is very like H. opalinus, but it has larger bare 
smooth spots along the elytral interstices. 
5. Hadromerus cretatus, sp.n. (Tab. VII. fig. 31, 2.) 
2. Moderately elongate, black; densely clothed with glossy pure white scales, and also set with a few fine 
erect hairs, those along the posterior half of the suture long and setiform. Head and rostrum together 
about as long as the prothorax, the rostrum canaliculate and moderately excavate; antenne with 
joint 2 of the fuviculus slightly longer than 1, the club elongate. Prothorax closely, finely punctate. 
Elytra comparatively short and broad, rather convex, the fine seriate punctures almost hidden by the 
densely placed scales, the interstices flat, each with an irregular scattered row of from six to eight, 
subangular, glabrous, smooth, slightly raised spots. Legs densely squamose and sparsely pilose; anterior 
tibiee strongly unguiculate and denticulate. 
Length 103, breadth 4 millim, 
Hab. Panama, Caldera in Chiriqui (Champion). 
One example. Distinguishable by the pure white, porcelain-like scales, which are 
so closely placed on the elytra as to almost cover the strie, the scattered, subangular, 
flattened, tuberculiform spots along the interstices, and the comparatively short, broad 
general shape.
