 filiform ; the clypeus often p;litters with silveror t^olden hairs, i^ome males are remarkable for the preat dilatation 

 of the anterieir tibia- and basal joint of the tarsi. The female of C. cribnirius provisions its nei?t with the lanae of

 lana with plant liei>.

'Fhe terntinal t'ralironites have the antenna; inserted neare- lie middle of the face, and thickened at the tips.

Phdaiitfnis, Fabr., has the cl\ peus trilnbed ; the basal seg"ment of the abdomen is narrowed iido a knot; tiie 

 antenna: suddenly thickened, [and the abdominal segments not constricted], and all the cubital cells sessile. 



Cerccrix, Latr. (Philatithns, Jur.), has the antentia- i^rradually thickened, [the abdominal se2;nieiits constricted], 

 ann the second cubital cell peduncled. 



The females of these insects make their nests in the sand, buryin;^ the dead bodies of Bees, Andrena^ and Wcc-

TriE DiPLOfTERA, 



Is the only one in this section ^vbich (with very few exceptions, Ceramius) has the fore-wings folded 



longitudinally; the anteiinie are ordinarily elbowed and clavafe, and. thickened at the tips; the eves 

 are imtclied ; the collar extends at tlie bides as far as the wings ; the fore-wings have two or three 

 compute cubital cells, the second of which receives two recurrent nerves: the body is glahrons and 

 black, more or less varied with yellow or fnhons. Many live in temporary societies, cninposed of 

 males, females, and neuters. The females which have withstood the severity of the winter com- 

 mence the ne&t and take care of the young wdiich tiiey prndtice ; they are subsequeiitlv assisted by 

 the neuters.
