Speciea of the American Genus A.9,iy\\\=>. 351 



related to, and peiiiiips a t'onn of, the Peruvian A. nif/ro- 

 femoralisy Pic *, wliich is said to have the, elytra luteo- 

 trilineate at the base and luteo-niaculate at the apex. The 

 last-named species is compared by him with A. pallipes, 

 Kirsch, from Ecuador. The longer head (especially in ? ), 

 rut'o-tcstaceous tibiae and tarsi, less coarsely punctured elytra, 

 &c., separate A. luteicmida from A. rived, Bnug. in all its 

 varieties. The J -armature is very similar in the two forms. 

 A. {Das^fgs) xanthuruH, Blanch., from ]\Ialdoiiado, also iias 

 a yellowish tip to the elytra.

 posteriorly and coalescent with tlie sutural stripe; all the 

 tibiae more or less curved in <J . 



(J. Anterior and intermediate tibite curved. Ventral 

 segment 5 broadly arcuato-emarginate, 6 conical, undivided, 

 deeply, triangularly notched at tip. Tegmen with very 

 long, somewhat spoon-shaped lateral lobes, which are Havo- 

 ciliate along their lower margin and at the apex. Penis-

Apparently an abundant insect in many parts of Brazil, 

 especially about liio de Janeiio, and often found gregariously 

 on flowers. The larger and darker foim {?revoili\ Pic) has 

 the lateral lobes of the (^ -tegnien rounded at the lip (not 

 incurved and truncate as in A. atromaculatus), and shaped as 

 in A. varieyatus. The head and prothorax are usually 

 metallic in the latter. The subapical spot on the elytra i.s 

 sometimes obsolete, sometimes (var. notatus) united with the 

 one on the opposite elytron into a common transverse patch.
