520 SUBFAMILY XII. COSSOXIX.E. 



Canada, Michigan and Ohio south to District of Columbia, 

 Florida and Texas. Occurs in red-rotten wood. (Ulkc.) 



The type of A. echinus Casey, described originally from New York, is 

 said by Casey (1895, 837) to be " in reality from Arizona, the label being 

 erroneous." Dury has recorded it from Cincinnati. It is pale yellow in hue, 

 with much longer elytra, more deeply constricted thorax, more numerous 

 and much longer bristles. Length 4.3 mm. 



Tribe II. ANCHONINI. 



The species of this tribe, which are nearly all Tropical Amer- 

 ican, have been associated with the Hylobiini by some authors, but 

 the form of antenna 1 (Fig- 13, r) indicates their relationship with 

 Cossonimp. They are recognized by their globose, deeply inserted, 

 almost smooth head, and the stout, curved, deflexed beak. The 

 eyes in the typical genus are depressed, finely granulated and 

 placed low down on the globular portion of the head, but in 

 Gononotits they are more coarsely faceted and placed at the sides 

 of the beak behind, while in Typhloglymma they are wanting. 

 These insects are found chiefly under the bark of decaying trees, 

 or by beating dead branches, or beneath driftwood and seaweed on 

 the coast. Some are thickly coated with an earthy incrustation 

 which hides most of their surface sculpture. The scales on the 

 upper surface are more or less setiforin and sometimes clubbed 

 at tip and often (in tropical species) arranged in fascicles on the 

 thorax and more elevated portions of elytra. 



KEY TO GENERA OF ANCHOXIXI. 



rt. Eyes present. 



&. Funicle 8-jointed; eyes placed low down on the globular portion of 

 the head. I. AXCHONUS. 



&&. Funicle 7-jointed; eyes placed at the sides of base of beak. 



II. GOXOXOTUS. 

 aa. Eyes wanting; funicle 7-jointed. III. TYPHLOGLYMMA. 



I. Axciioxrs Schcn., 1820. (("Jr., "strangled or narrow.") 



The chief characters of this genus, aside from those mentioned 

 in key, are the subovate, rigid, scabrous body, absence of scutel- 

 lum and inner wings and contiguous front cox;e. The first joint 

 of funicle is short, second elongate, obconic, 4 8 short, subper- 

 foliate, the outer ones gradually a little thicker; club short, ovate, 

 solid and pubescent in our species. The males are separated from 

 the females by the shorter and less cylindrical apical portion of 

 the beak. Nearly 100 species have been described, mostly from 

 the Antilles or the main land of Tropical America, the genus ex- 

 to Chili and the Cocos and Galapagos Islands.
