258 RHYNCHOPHORA. 
Seven specimens. In this insect the very prominent median carina of the rostrum 
is bifurcate behind and encloses the deep lanciform inter-ocular sulcus, a character 
separating E. carneipes from its allies. ‘The general coloration of the vestiture is 
similar to that of Pandeleteius erubescens, except that the base and apex only of the 
elytra are carneous or cupreous.

3. Prepodes mexicanus, Sturm, in litt. *. 
Elytra with a more or less distinct foveiform depression or bare spot on the fifth interstice at about the basal 
third and often another on the second or third interstice beyond the middle; narrow and subparallel in 
their basal half in g, much broader and widened to the middle in 9, the dorsal striae sometimes 
interrupted or sinuous in this sex. Rostrum finely carinate, the cariua followed by a narrow sulcus. 
Eyes somewhat depressed in Q, a little more prominent in 3. Scales varying in colour from whitish 
or cinereous (with cupreous reflections) to green, the elytra often with denser patches on the disc and the 
prothorax with a faint submarginal denser stripe on each side, the vestiture frequently covered in part 
or disguised by a yellowish powdery exudation; the head, rostrum, and legs sometimes cupreous. 
Anterior tibisee unguiculate. 
Var. a. The scales green or bluish-green, those on the head, rostrum, and legs more or less cupreous or 
golden. [Fig. 20, 2? .] 
Length 63-10}, breadth 23-41 millim. (d 2.)

The types of the four species described by Boheman and Gyllenhal have been 
examined by Dr. Sharp or myself, and there can be little or no doubt that they all 
belong to one variable insect, for which the most appropriate name would be farino- 
lentus: G. agrestis was based upon a single example (2 ) completely encrusted with dirt, 
LL. canus and P. canescens upon poor specimens ( ¢ ), and P. farinolentus upon an 
individual (2 ) with the characteristic vestiture intact. About 100 examples are now 
available for comparison (including long series from Teapa, Cordova, Jalapa, Toxpam, 
&c.), and these show great variation in the colour of the scales; the metallic green 
variety, with cupreous rostrum and legs, is from Santacomapan in Vera Cruz, and the 
other green specimens are from Teapa or Chiapas. The foveiform or bare depressions 
on the third and fifth elytral interstices (unnoticed in Schénherr’s work, though clearly 
visible in the dirty type of G. agrestis) are not accidental or due to abrasion, as they 
are also to be found in Z. nubilus, E. distigma, &c. We figure four specimens: a
