ANLDBYTTTS.— EPOPTEEUS. 129 



there is on each an indeterminate black spot touching the base, and the greater part of 

 their disc is black, leaving the margins, the apex more widely, the suture, and a ring 

 surrounding the black spot deep rusty-red. Legs and body beneath paler red. 



This species is allied to A. humilis ; it differs not only in colour, but in the punc- 

 turing and a little in the form of the thorax, which being less narrowed in front appears 

 wider. The male characters are the same as in A. humilis. 



A single specimen.

Epopterus is a Tropical-American genus, and is known to contain about twenty-five 

 species, ; its representatives, however, unlike those of Anidrytus, present great beauty 

 and variety in the pattern of their upper surface. The species of the first section bear 

 a remarkable likeness in form to those of the European genus Myeetophagus. They are 

 to be sought for in similar places and in similar substances to the Anidryti. 



Section A. Body oblong, of nearly even width before and behind.

This insect is so widely distributed and is so variable that it is difficult to determine 

 whether all the forms belong to one species. The richly coloured typical specimens 

 from Colombia and Brazil have a very different aspect from the varieties which occur 

 in our district ; yet it appears to me impossible to separate them satisfactorily. The 

 variety d, which seems to be rather common in Nicaragua, has four distinct thoracic 

 spots, and the elytra yellow, with two basal spots, an interrupted fascia, an apical spot, 

 and one common wedge-shaped one on the suture. Specimens from Guatemala agree 

 with these, excepting in having the fascia not divided in the middle of each elytron. 

 The variety b, which I have seen labelled " myops, Guerin," has two subapical spots
