hind one subquadrate, convex, broader, covering the meso- 

 thorax ; meso- and metanota unarmed ; elytra reaching to near 

 apex of abdomen, their venation as in fig. 15 ; front coxae about 

 as long as tibiae, front trochanters unarmed ; front femora 

 slightly longer than tibiae and tarsus united, armed beneath 

 with a series of rather long spines and intervening shorter 

 setae and hairs, reaching from base to beyond middle ; lower 

 face of front tibiae with a complete series of short denticles ; 

 front tarsi with three distinct joints and two equal claws. Two 

 species are known, one occurring in our territory. 



500 ( — ). Lutevopsis longimanus Champion, 1898, 166. 



Pale reddish-brown to piceous, shining; elytra fuscous-hyaline, the 

 veins dark; connexival sutures each usually with a small pale spot; 

 ventrals fuscous-brown. Head three-fifths as long as broad, tapering in 

 front, more so behind (fig. 14), the front lobe with a short deep median 

 impression near base. Pronotum as above described, the front lobe 

 scabrous, hind one finely transversely rugose. Front legs slender, coxae 

 one- sixth shorter than tibiae, the latter feebly curved. Sixth dorsal of 

 male broad, curved upward, covering the genital segment, its tip nar- 

 rowly truncate. Other characters as under generic heading. Length, 

 9 — 10 mm.

IV. Ploiaria Scopoli, 1786, 60. 



Small, slender-bodied Ploiarids having the head almost as 

 broad across the eyes as long, suberect, declivent behind ; 

 pronotum distinctly longer than wide, not extending over the 

 mesonotum, the latter covering the mesothorax in the winged 

 forms, its sides usually carinate and disk not tuberculate; 

 meso- and metanota unarmed ; elytra, when present, reaching 

 to or beyond apex of abdomen, with venation as in fig. 21 ; 

 front coxae almost as long or longer than fore tibiae, the latter 

 less than half the length of femora, which are spinose from 

 the base; front tarsi claw-like and rigid, the joints fused into 

 one which is curved, compressed and sometimes almost as long 

 as the tibiae; front trochanters armed with setae or slender 

 spines. 



McAfee & Malloch (1925, 48) have combined with Ploiaria 

 the genera Luteva Dohrn and Ploiariopsis Champ., and have 

 recognized 22 species. Of these four occur in the eastern
