BRUCHIDiE. — BRUCHUS. 213 



anterior angles rounded, truncate behind, with a lobe in the middle, opposite 

 to the scutellum, which is subquadrate : elytra oblong-quadrate, shorter than 

 the abdomen, slightly convex : pygidium large, rounded, descending : legs 

 short : femora sometimes dentate, posterior incrassate : tibiw rounded ; tarsi 

 rather short. 



The filiform, curved, and compressed antennae, of which the inner 

 edge is more or less distinctly serrated ; the equal palpi, incrassate 

 posterior femora, exserted head, &c. are the more manifest external 

 characters of this genus, the species of which subsist in their larva 

 state upon seeds *, to wliich in some cases they are very destruc- 

 tive, especially in pea warehouses. 



A. Femora dentate. 

 Sp. 1. Pisi. Niger, antennarum articulis quatuor basalibus, tibiis tarsisque 



anticis, tibiarumque intermediis apice rufis, thoracis lateribus unidentatis.

Black, with the Jour basal joints of the antenna;, the anterior tibice and tarsi, 

 the apex of the intermediate tibia and their tarsi ruio-ferruginous : thorax 

 with a griseous spot in the middle of the base, the lateral margins unidentate : 

 elytra striate, with griseous spots, some of which are disposed in transverse 

 fovejE : anus of the male whitish, with two dusky spots : posterior femora with 

 an acute strong spine. 

 Found occasionally within the metropolitan district, but I suspect 



not a truly indigenous species : it sometimes abounds in depositories 



of peas to a very destructive extent. 



Sp. 2. granariusi Niger, thorace elytrisque albo punctatis, antennarum basi 

 pedibusque anticis rufo-testaceis, femoribus posticis unidentatis. (Long. corp. 

 l|-2i lin.)

/. IT. 

 Black; antenna at the base and anterior legs entirely rnto-testaceous : thorax 

 with the lateral margins a httle sinuated, the disc with ashy- white hairs, and 

 two whiter spots, and towards the middle of the base a larger triangular one: 

 elytra punctate-striate, with a griseous-white streak near the scutellum, and 

 some scattered whitish spots on the disc : apex of abdomen ashy- white, with 

 two oblong fuscous spots. 



* Very many species of this genus have been taken in Britain that have 

 evidently been introduced with their food ; such I have not thought fit to insert.
