190 Dr. Brendel's Descriptions of New Pselaphidse. 



The new species from Tennessee is 



1. Fustiger Fuchsii, n. sp. — Testaceus, translucens, variolatus, pubeseens, ca- 

 pite obconato, antennis 2-articulatis in fossa magna sub frontis margine insert- 

 is, articulo secundo obeonico, oculis parvis lateraliter insertis, oeellis binis in 

 occipite dispositis. Tborace rotundato, variolate, elytris truncatis, abdomine 

 fovea magna ad basin impresso. Long- 2.0 m. m. 



The stature of this insect resembles most that of Adranes coecus Lee. 

 The head is conical, widest between the eyes ; the front is slightly im- 

 pressed in the middle ; the antennas are inserted in large grooves be- 

 low the lateral margins of the front, which extend to the middle of the 

 face, leaving only a small ridge running from the clypeus to the front- 

 al impression; the vertex is variolate, thinly pubescent; the eyes are 

 situated laterally near the base and consist of but eight facets ; ou the 

 occiput are two ocelli consisting of but three small facets. The anten- 

 nae are 2-jointed, the first joint small, cylindrical, of equal dimensions, 

 the second is obconical, 1J times as long as the head, and at the end 

 four times as wide as at the base, consisting of six false connate joints. 

 The maxillary palpi are apparently two-jointed. The thorax is round- 

 ed, not longer than wide, variolate, pubescent, slightly depressed above, 

 with a variolate scar at the base. The elytra are a little truncate at the 

 posterior, exterior angles, variolate, pubescent, the sutural striae distinct. 

 The abdomen consists of three dorsal and five ventral segments; the 

 first dorsal segment is very large and has a deep groove at the base, 

 extending from side to side, in the depth of which are the coxal arti- 

 culations shining through ; behind the groove the segment is convex, 

 smooth, thinly pubescent. The margin of the first segment is broad 

 and shows beautiful convolutions and folds near the base. The ante- 

 rior coxae are conical, the intermediate more globose, the posterior 

 transverse ; the trochanters are half as long as the femur, the tibiae are 

 strongly pubescent ; the tarsi are two-jointed and have but one claw. 



This specimen seems to be a female. It was presented to me by Mr. 

 Henry Ulke, and was discovered by Mr. Fuchs, of East Tennessee, 

 to whose honor and for instigating him to work more in that line, it 

 was named after him. 



2. Ctenistes monilicornis, n. sp. — Castaneus, pubescens, minutissime punctu- 

 latus, capite 4-foveato, fronte elongata, antennis moniJiforraibus ; palpis minu- 

 tissimis appendiculatis, thorace obcordato trifoveato, elytris latis, tibiis posticis 

 dilatatis. Long. 2.8 m. m. 



The insect before me seems to be in every respect a Ctenistes. The 



general form agrees entirely with that genus ; the palpi, though so 



very small that they cannot be seen but by a magnifier of 200 diame-
