THE CLICK BEETLES. 77o 



XLIV. Perotpiops Erichs. 1842. (G-r., "to pierce + face.") 



To this i;enus belong two medium-sized; oblong, robust species 

 having the first joint of antenna? elongate, conical, second one-third 

 as long, third twice the length of second and one-half longer than 

 fourth. One of the two occurs in Indiana. 



1474 (45.'JS). Peeothops mucida Gyll., Schon. Syn. Ins., IsiiT, 133. 



Oblong, parallel. Piceous, male ; reddish-brown, female ; feebly shin- 

 ing; sparsely clothed with very fine grayish pubescence. Thorax short, 

 wider than long, narrower in fnmt, sides feebly curved, male, more strongly, 

 female, slightly sinuate in front of hind angles, which are short, subacute, 

 feebly diverging, not carinate; disk very finely punctate, with sparse and 

 coarser punctures intermixed, a feebly impressed median line on basal half. 

 Elytra striate, the stria> indistinctly punctate; intervals flat and equal, male, 

 or alternately slightly narrower and more convex, female, finely punctu- 

 late. Length 11-18 mm. 



Monroe, Posey and (Irawford counties; scarce. May 12— June 

 11. Occurs on the trunks and l>7anches of old beech trees. 



' Subfamily IV. CEROPHYTINAE. 



While no member of this subfamily has been taken in Indiana, 

 it is doubtless represented in the southern third of the State by a 

 rare species, dn-dphiilvm piilf^nlor Uald.. a single specimen of which 

 was taken l)y Dury near Cincinnati. It is an oblong black beetle, 

 7. .5-8.5 mm. in length, with the hind eoxal plates wholly wanting; 

 tarsal claws jx'ctinate on l):isal hidf ; antcnn-_c ]);'ctinate in male, ser- 

 rate in female; elytra deeply striate, the striT ciarsely and closely 

 punctate. 



Family XX'XVIII. THROSC^ID.E. 

 The Pseudo Click Beetles. 



This family contains only a few small oblong black or brownish 

 beetles which resemble tlie Elaterids, and the ne.xt family, the Bu- 

 prestids, in form and in having- the prosternum prolonged behind 

 into a spine which fits into a cavity in the mexosternum. They 

 differ from the Elateridas in having the pro- and mesosterna firmly 

 .ioined, thus preventing the power of leaping possessed by most click 

 beetles. From the Buprestidu' they are distinguished by having the 

 ventral abdominal sc<i,mcnts all free. The adult beetles are found 

 on flowers, while the habits of the larva- arc as \'et almost unknown. 



In addition to the characters above mentioned, the Throscids 

 have the antenna' 11-jointed, inserted on the front, and in repose
