AMERICAN ENTOMOLOGY. 2 ( J 



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 sid< 

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

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

 abdomen depressed, fusiform, margined ; margin paler. 



Obs. Of this genus Fabricius has described two speeii 

 which the tipularius 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 

 responsibility of separating them. 



The smaller figure in the plate denotes the natural size. 



PELECINUS. Plate XA r . 



Generic character. Antennae with not more than fourteen 

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

Pelecinus polycerator Fabr., Latr. 



Dene. Head with a compressed, elevated scale-like tooth a' thi 

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

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

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

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

 inner side, the tarsi piceous.
