what in sculpture, hut the Nellow basal joint of the antennae is always 

 present, and in connection with the other characters may he relied on to 

 distinguish the species ; from tnxjliKli/tcx the 8])ecies is readily separated 

 by the thorax and the antennae, though the % % have very much the 

 general habitus of trdrilodijfcx. It does not seem to be very common. 



A. li-Oiflodytes Maim. Bull. Mosc, 1S4."?, 289 : metallirum, Gerr^t. Stet. Ent. 

 Zeit. 1S;")4, 24.'. — Black, .sometimes with a brassy tinge, densely pubescent, the 

 brassy specimens sometimes less so. Head broad, eyes distinct, but hardly promi- 

 nent, vertex finely punctulate and snlcate ; a more distinct sulcus at base of ros- 

 trum, the latter rather short, equal and stout j antennae stout, basal joint exceed- 

 ing second and third, second stoutest. Thorax transverse, widest near base, and 

 very slightly constricted at base; evenly and rather sparsely punctured, with a 

 short foveate line not attaining the middle. Elytra hardly one-half longer than 

 wide; sides equal, or very slightly ovate; striae narrow, evidently punctured: 

 interstices wide, flat and finely rugose. Length 1 — l..i mm. 



Hah. — Southern and Southwestern States. 



A conmion species, and greatly varying in size, less in form and pu- 

 bescence. It ha.s a squat, compact appearance, which is j)eculiar to it, 

 and somewhat so to this group. The color is somewhat variable, and the 

 aeneous specimens are usually least pubescent. One of these probablv 

 furni.shed the type of metaUicnm, Gerst. 



A. extensiilll n. sp. — Black, densely pubescent, except feet and antennae. 

 Of the general form of the preceding, but punctuation throughout fine and even ; 

 no thoracic line, striae fine, punctures small, intervals flat. Length 2 nun. 

 Hdh. — Mont.. Kans. 



This species is rather more elongate than the preceding. l)ut of the 

 same general form. The lack of pubescence on the legs and antennae 

 makes these members seem intensely black, and gives the insect a pecu- 

 liar appearance. Two specimens only, received from Mr. Ulke. 



A. neneipeillie n. sp. — Blackish bronze, not ]iubesceiit, foi-m robust. Head 

 and thorax finely and densely punctured, the latter with a foveate puncture near 

 base, where it is also widest. Elytral .striae fine, narrow; punctures small, inter- 

 vals widi'. flat and smooth. Beneath moderati'ly and evenly punctured. Length 

 2 mm.

Eusilv distinguished by the brassy or l)roiize black color and robust 

 form. Two sjtecimens only, from ^Ir. T'lkc. 



A. COiitiiSlim n. sp. — Grayisii black, basal joint of antennae yellow. Head 

 short, transverse ; eyes small, not at all prominent; front longitudinally rugose, 

 antennae long and slender, basal joint longest and very slender. Thorax inoder-
