340 PHYTOPHAGA. 



SANGARIA. 



Sangaria, Harold, Coleopt. Hefte, xv. 1876, p. 13. 



A species from Bogota served Von Harold for the erection of this genus, the principal 

 characters of which consist in the long posterior femora, which project beyond the apex 

 of the elytra, the thoracic groove closely approached to the basal margin, the short 

 second and third joints of the antennae, the punctate-striate elytra, and the closed 

 anterior coxal cavities. All these characters apply perfectly to a species obtained 

 abundantly by Mr. Champion, which I must therefore refer to Von Harold's genus and 

 species.

I have little doubt that the numerous specimens before me are identical with Von 

 Harold's species, although there are some differences which would perhaps justify me 

 in considering it as specifically distinct. I give here a renewed description of the 

 species : — 



Head impunctate, the frontal tubercles distinct and divided by a longitudinal groove ; antennae two thirds the 

 length of the body, the third joint slightly longer than the second, the fourth joint as long as the 

 two preceding ones together ; thorax quadrate, scarcely broader than long, fulvous, the angles produced 

 into a short tooth, the posterior ones sharply and obliquely cut, the posterior groove deep and its sides 

 somewhat oblique and closely approached to the basal margin ; elytra with the base distinctly raised, each 

 elytron with about ten rows of closely approached and distinct punctures distinct to the apex, those at the 

 sides somewhat transversely shaped and slightly rugose ; prosternum narrow ; first joint of the posterior 

 tarsi as long as the three following ones united ; anterior tarsi in the male dilated ; tibiae widened towards 

 the apex and slightly channelled longitudinally, their apices as well as the tarsi black ; femora as long as 

 or longer than the elytra. 



Von Harold gives the length of the antennae as of that of the body ; in none of the 

 numerous specimens before me do they attain this length. The punctuation of the 

 elytra is distinct to the apex, which is not the case according to the description of Von 

 Harold. The tarsi and the apices of the tibiae are black in most of the Central- 

 American specimens, but in some they are reddish. The insect seems to be subject to 

 great variation in size and colour, and even the sculpture of the elytra differs considerably. 

 I have undoubted females from one locality before me which have the elytra either 

 costate at the sides (from the shoulder to the middle) or smooth, and with the fourth 

 joint of the antennae double as long as in other specimens ; yet I cannot find any other 

 characters for separating these different forms ; sometimes the antennae have the three 

 basal joints fulvous, sometimes they are entirely of that colour or black, and the same 

 is the case with the underside. A well-marked character of the present genus is the
