StapliijliuidcB of the Amazon Valler/. 41 



Obs. — A closely allied but distinct species occurs at 

 Rio de Janeiro. 



Falagria. 



The species of tliis widely distributed genus appear to 

 be more numerous in tropical America than elsewhere ; 

 23 species of the genus were described by Erichson, and 

 of this number no less than 14 were from the quarter 

 of the globe above mentioned. I here describe three new 

 species, but I have no doubt numerous others are to be 

 found in the Amazon valley. These three species are very 

 dissimilar inter se ; the F. Puree appears to be rather closely 

 allied to the Eastern F. Jiavocincta, Kr., and F. fovea. 

 Sharp ; F. varicornis is remarkable not only from the 

 great development and elegant colour of its antenna?, 

 but also from the point of insertion of these organs, this 

 appearing to be actually nearer to the vertex than to the 

 front margin of the head. F. ciirtipennis is a very pecu- 

 liar species ; its abbreviated elytra and breast, together 

 with the slender and elongate limbs, give it a peculiar 

 facies ; and moreover the mesosternimi shows no trace 

 whatever of that division into distinct plates, which is so 

 conspicuous in F. ohscura, and others of the genus ; it is, 

 therefore, very probable that the species may ultimately 

 be considered to belong to a distinct genus. 



1. Falagria Farce, n. sp. Rufescens, antennis medio 

 infuscatis, basi cum pedibus testaceis, femoribus basi 

 excepto fuscis, elytris abdomineque fuscis, illis humeris, 

 hoc basi testaceis ; capite thoraceque laevis, nitidis, hoc 

 profunde canaliculato ; abdomine dense subtilissime punc- 

 tulato. Long. corp. 1^ lin. 



Antenna3 rather stout, very nearly half a line in length ; 

 the two or three basal joints pale reddish, the following 

 ones infuscate ; the 10th and lltli again reddish; 3rd 

 joint shorter than 2nd ; 4 — 10 differing very little from 

 one another in length, each a little stouter than its prede- 

 cessor ; the lOtli about as long as broad; 11th scarcely 

 broader than, but twice as long as the 10th, obtusely 

 pointed. Head obscure reddish, shining, impunctate, witli 

 a transverse impression between the points of insertion 

 of the antennas, its breadth about equal to the thorax. 

 Thorax reddish, impunctate, with a deep channel along 

 the middle, rather longer than broad, much narrowed 

 towards the base. Elytra yellowish at the base, elsewdiere
