Form of filiformc but stouter. Black, shining, densely clothed with 

 pale scales narrow on thorax, broad and denser on elytra, moderately 

 dense on the abdomen; antennas and legs dark reddish-brown. Beak stout, 

 as long as thorax, punctured and scaly near the base. Thorax slightly wider 

 than long, widest at apical third; sides parallel from base to beyond middle, 

 then strongly rounded and constricted to apex; disc rather coarsely, uneven- 

 ly, not densely punctate, with a very narrow smooth median line. Elytra 

 at humeral umbones obviously wider than thorax; strife fine, deep; inter- 

 vals flat, coarsely, confusedly punctate. Length 3.1 3.3 mm.

XXXI. Erxvssoiu.v Casey, 1S<> ((Jr., "spiny" + "life.") 



This generic name replaces Eucliwtcs Lee., which was preoc- 

 cupied. To it belongs a very singular insect having the beak ex- 

 tremely slender, cylindrical, strongly curved, abruptly inflated 

 behind the antenme; mandibles very short, thick, compressed, 

 bent upward and moving in a nearly vertical plane as in Bnl- 

 'iii in tin, the condyles being received in broad, deep fissures at the 

 sides of the buccal opening beneath, thus affording a broad base 

 for the attachment of muscles and forming a most effective 

 boring apparatus; antennae inserted beneath the beak, near basal 

 third, their grooves inferior, confluent behind, scape reaching 

 the eyes, first and second joints of funicle subequal in length, 

 3 7 much shorter; tarsi long, slender, the third joint not wider 

 than second, claws simple, divergent.

. Oval, feebly convex, narrowed before and behind. Dark brown, densely 

 covered with a crust of pale, dark brown and whitish scales, intermixed 

 above with long, stiff, erect bristles, the pale brown scales covering the 

 thorax and base of beak, the whitish ones forming large patches at base and 

 smaller ones near apex of elytra and densely covering the legs and under
