404 PHYTOPHAG-A. 



anterior femora fulvous, this colour predominating on the posterior femora, in which the apices only are 

 black; the first joint of the posterior tarsi as long as the two following joints united ; prosternum narrow, 



convex.

The colour of the head and legs in connection with the nearly impunctate upper 

 surface, which is constant in the sixteen specimens before me, will assist in the recog- 

 nition of this species amongst its unicolorous allies ; the colour of the elytra in one 

 specimen is testaceous. A. pallida, Jac, is much larger and broader, and has the 

 underside and legs black, and the thorax of a different shape. Only a single specimen 

 from Mexico is before me ; it differs in no way from the Guatemalan examples.

In the typically coloured specimens of a pale testaceous colour three narrow white 

 transverse bands interrupt the ground-colour ; but in the variety these bands are absent, 

 and the entire insect is of a pale testaceous colour, in which coloration it is not always 

 easy to recognize the species from those similarly unicolorous.

The upper surface of this species varies from-pale grey to light brownish or yellowish, 

 the head, scutellum, legs, and antenna? being black, and the abdomen at the apex or at 

 the sides fulvous. The elytra are entirely impunctate, by which character the species 

 may be at once distinguished from A. balyi, Clark, and the prosternum in the male (?) 

 is produced posteriorly into a sort of tubercle, also known to exist in some other species 

 of the genus. • A single specimen, obtained in Chiriqui by Mr. Champion, differs from 

 the others in having a bright rufous thorax and rather longer antenna? ; other differences 

 of importance I am unable to find. 



15. Asphsera nigrofasciata. 



Below piceous ; head black or piceous ; thorax and elytra flavous, impunctate, the latter with a broad transverse 

 band at the base, and another narrower one behind the middle, black ; abdomen testaceous. 



Length 3 lines. 



Head with a few fine punctures round the inner margin of the eyes ; the frontal tubercles strongly raised, 

 obliquely trigonate ; antennse black or dark fulvous ; thorax narrowed in front, the anterior angles acutely
