the densely pubescent basal area extending well beyond the middle and not 

 sharply defined, the pubescence of the remaining parts being in large part similar 

 in color but sparser. Length 5. 7—7.4 mm.; width 2.5-3.2 mm. Vancouver Is- 

 land and New Mexico (Fort Wingate) signatus Fee. 



12 — Body oblong-oval, more depressed than usual, pale rufo-ferruginous throughout 

 above and beneath and clothed with rather sparse fulvous pubescence, the elytra 

 black, except at the basal margin and along the sides to basal fourth or more, 

 the black parts clothed uniformly with inconspicuous blackish pubescence ; ab- 

 domen without quasi-denuded spots. Length 6.3 mm.; width 3.0 mm. Illinois. 



pulcher Lee. 



13 — Narrow and convex ; body and legs throughout uniform dark piceous-brown in 

 color, the pronotum rather finely, not very densely punctate, deeply and narrowly 

 bisinuate at base, broadly biimpresseel at the basal margin, with rounded hind 

 angles, the vestiture uniform throughout and consisting largely of fulvo-cinereous 

 hairs ; elytra clothed rather sparsely with dark pubescence, with fulvo-cinereous 

 hairs sparsely and uniformly interspersed throughout ; pubescence of the under 

 surface denser and uniformly flavo-cinereous, the abdomen without quasi-denuded 

 spots. Length 6.7 mm.; width 2.7 mm. Texas (El Paso). 



angustus, sp. nov. 



Sobrinus of LeConte, I have been unable to identify amidst the 

 material accessible to me. Rattus and signatus are by no means 

 varietal forms, but perfectly valid and very interesting species ; 

 mannerheimi seems, however, to be a variety of the very widely dis- 

 tributed caninus ; it is wholly different from marmoratus , as I have 

 previously pointed out (Bull. Bk. Ent. Soc). The identity of 

 mucoreiis and carnivorus rests upon the authority of the HSmshaw 

 List. Say described his nubilus from Florida and Pennsylvania, and 

 the characters given coincide entirely with those of caninus and 

 not with the more pubescent form named nubipennis above. 



Attagenini. 



This is the largest tribe of the family, and contains a considerable 

 number of genera having the legs more or less free throughout. The 

 laminate portion of the hind coxse extends about half way across the 

 end of the parapleural ; the epipleuras are distinct and generally 

 strongly defined toward base, and the prosternal process is visible, 

 though generally narrow, between the coxse, its free tip resting in an 

 apical pit of the mesosternum which is frequently prolonged to the 

 apex of the latter as a well-defined sulcus or fossa. The antennas are 

 of varied structure, and the antennal fossa may be traced in successive 

 stages of development through the genera in an instructive and inter- 

 esting manner. In the first four or possibly five genera of the tribe,
