AMERICAN ENTOMOLOGY. 29 



Desc. Antennae longer than the body, terminal joint fuscous, 

 yellowish at base and tip : eyes black : stemmata sanguineous, 

 distant, placed very far back, almost lateral : clypeus produced, 

 conic ; rostrum as long as thorax, inflected, and placed in a groove 

 beneath : thorax gibbous behind, punctures large and crowded : 

 scutel with an elevated spine : elytra nervous, with a black costal 

 spot near the tip : posterior feet longest ; a spine each side as 

 thick as the thighs, originating before the posterior coxoe, curving 

 upward above the elytra, and abruptly attenuated near the tip : 

 abdomen depressed, fusiform, margined ; margin paler. 



Ohs. Of this genus Fabricius has described two species, of 

 which the fijndarius appears to be very like this insect — at least 

 as far as I can judge from description, having no opportunity to 

 consult a figure of either insect of the genus. One specimen in 

 my cabinet has the antenna) rather shorter, and on the thorax are 

 three lines a little elevated, one of which is dorsal and two mar- 

 ginal, with a two-lobed raised transverse spot before : this may 

 be a sexual variety, or possibly a distinct species ; but, for want 

 of sufficient knowledge of them, I will not, at present, incur the 

 responsibility of separating them. 



The smaller figure in the plate denotes the natural size. 



PELECINUS. Plate XV. 



Generic character. Antennae with not more than fourteen 

 joints; tongue trifid; neck not apparent; posterior tibas clavate ; 

 abdomen slender, elongated, filiform, inserted at the posterior and 

 inferior extremity of the metathorax. 



Pelecinus polycerator Drury. — Specific character. Black ; 

 antennae with a white annulus ; posterior tibia sericeous on the

Pelecinus polijcerator Fabr., Latr. 



Desc. Head with a compressed, elevated scale-like tooth at the 

 inner base of each antenna : antennae, tenth joint and half of the 

 ninth joint white : wings, nervures and costal margin fuscous : 

 feet, two anterior pairs blackish-piceous ; posterior pair black, 

 polished, the tibia much dilated at tip and much dilated on the 

 inner side, th^ tarsi piceous.
