678 FAMILY XXXIII. - PARNILVK. 



Subfamily II. PARNINAE. 



In our genera of this subfamily the head is retractile and pro- 

 tected beneath by the prostenmm, which is lobed in front; antenna 1 

 short, 11-jointed, the first and second joints enlarged; prosternal 

 spine wide ; mesosterimm broad, emarginate ; hind coxa? dilated into 

 a plate. Four genera are known, three of which may occur in the 

 Slate.

(i. Body rounded; eyes not hairy; last joint of maxillary palpi hatchet- 

 shaped; length 3 nun. I.rTuorurs. 



aa. Body elongate; last joint of maxillary palpi elongate; larger, 5-0.5 mm. 

 b. Anteume close together at base, their clubs pectinate; eyes hairy. 



PELONOMUS. 

 67>. Antennae widely separated, their clubs lamellate; eyes glabrous. 



II. DRYOPS. 



s lutens Lee., oval, bronzed, densely clothed with clay- 

 yellow hairs, has been recorded by Dury from Cincinnati. 



I't IOHOHIUS obscurux Lee., siibeylindrical, piceom, densely clothed 

 with erect hairs, length 6.5 mm., is recorded from the "Southern 

 and Western States." 



II. DRVOPS Oliv. 1700. (A mythological name.) 



Oblong species of medium sixe, having the head retractile and 

 when bent downward protected beneath by the lobe of the pro- 

 sternum; joints 4 to 1 1 of antenna 1 distinctly lamellate; prosternal 

 spine wide. Five species are kno\\n from North America, two of 

 which have been taken in Indiana, while a third probably occurs.

1296 (3921). DRYOPS LITHOPHILUS Germ., Ins. Spec. Nov.. 1S24, ss. 



Oblong, subconvex, everywhere covered with a dense and evenly dis- 

 tributed silky pubescence which lias a slightly bronzed lustre. Thorax 

 broader than long, disk convex, base Insinuate, front and hind angles acute. 

 Elytra rapidly narrowed behind the middle to an acute apex: last ab- 

 dominal segment, as in the next species, nearly devoid of pubescence and 

 reddish in hue. Length 5-5.5 mm.
