The S uieasnres scarcely 1.5""", and (titters from the 5 as follows: 

 The head is nnn-e rounded ; the llagelhir Joints are a little longer than 

 wide, while the abdomen is shorter and more nearly oval, or short 

 ovate. 



Habitat. — Washington, D. C, and Lafayette, Ind. 



Types in Coll. Ashmead. 



I first reared this species from raisins infested with !Silv(inits suri- 

 namensis and other Coleoptera; subsequently Prof. P.M. AVebstersent 

 me several specimens which he reared in Indiana from i^ilvanus siiri- 

 namensis infesting stored grain. It comes quite close to A. Fiirsteri 

 Kirch., of Euroi)e, but differs in being perfectly smooth, impunctured.

(PI. Ill, Fig. 4, 9.) 



Head large oblong or subquadrate, flattened; eyes in 9 minute and 

 composed of only a few hexagons; ocelli wanting; clypeus anteriorly 

 trituberculated ; in the $ the eyes are normal and the ocelli are 

 present. 



Antenna^ 13-jointed, short, the first joint long, the second a little 

 longer than the third, the following short; in the S the flagellar joints 

 after the second are a little longer. 



Maxillary palpi deformed, 4-joiated; labial palpi 3-jointed. 



Mandibles slender, curved, armed at apex with two large teeth. 



Thorax in 9 elongate, the prothorax large, suboval; mesothorax 

 short, the dorsum subcordate; metathorax oblong, contracted near the 

 base, the angles rounded; in i elongate, the pronotum very long, nar- 

 rowed anteriorly, the mesonotnm with one distinct furrow, the meta- 

 thorax quadrate. 



Wings in $ similar to Epiirls, the stigma very minute, the radius 

 very long and slender. 



Abdomen in 9 elongate oval, in $ ovate. 



Legs in 9 short, thick, fossorial, middle tibia* compressed and spin- 

 ous, the anterior tibia* terminating in two spurs and the basal joint of 

 the tarsus is lunate and armed on the under side with a row of very 

 fine short bristles; the middle legs, on the contraTy, are very robust, 

 the tibia' strongly serrated on the outer margin and the spurs finely 

 spined; in the middle legs the tarsi are longer than the tibia* and have 

 the under side of the three basal joints finely spined. 



The slender, bidentate mandibles and 4-jointed deformed maxillary 

 l)ali»i,sutficiently distingnish the female of this genus from other wing- 

 less genera. Tiie nude, which is here described for the tirst time, comes 

 nearer to the genus Dissomplialus than to any other, but the mandibles
