THE CLICK BEETLES. 773 



XLIV. PEROTHOPS Erichs. 1842. (Gr., "to pierce + face.") 



To this genus belong two medium-sized, oblong, robust species 

 having the first joint of antenna. 1 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 (4538). PEROTIIOPS MUCIDA CJyll., Schon. Syn. Ins.. 1si!7. 1 :.>:!. 



Oblong, parallel. Piceons, male; reddish -Id-own, female; feebly shin- 

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

 wider than long, narrower in front, 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 stri;e 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 Crawford counties; scarce. May 1'2-June 

 11. Occurs on the trunks and branches 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, ft t'ojiln/hnit ftuh.nl or llakl.. a single specimen of which 

 was taken by Dury near Cincinnati. 11 is an oblong black beetle, 

 7.5-8.5 mm. in length, with the hind eoxal plates wholly wanting; 

 tarsal claws pectinate on basal hall'-, antenna 1 pectinate in male, ser- 

 rate in female; elytra deeply striate_ th" stri-e c'nrse'y and closely 

 punctate. 



Family XXXVIII. THROSOIIXK 



THE PSEUDO CLICK BEETLES. 



This family contains only a few small oblong black or brownish 

 beetles which resemble the Elaterids, and the next family, the Bu- 

 presticls, in form and in having the prosternum prolonged behind 

 into a spine which fits into a cavity in the me.snsternum. They 

 differ from the Elaterida> in having the pro- and mes-;s1erna firmly 

 joined, thus preventing the power of leaping possessed by most click 

 beetles. From the Bnprestidu 1 they are distinguished by having the 

 ventral abdominal segments all tree. The adult bed Irs are found 

 on flowers, while the habits of Ihc larva- are as yet almost unknown. 



In addition to the characters above mentioned, the Throscids 

 have the antenna 1 11-jointed, inserted on the front, and in repose
