(Type J. Ji(rhieanu8 Latr.) 



Head transverse, the vertex wide, convex or subconvex, the occiput 

 slightly concave, margined; ocelli in a triangle; eyes ovate. 



Antennte inserted just above the clypeus, lO-jointed; in the 9 sub- 

 clavate, the first flagellar Joint hardly one-third the length of the scape, 

 the following joints short, the terminal joints thickened gradually; 

 in S filiform, pilose, <u- pubescent, the first flagellar as hnig or shghtly 

 longer than the scape, the following joints all lengthened, cylindrical. 



Maxillary palpi 4-jointed; labial palju very short, 2-jointed. 



Mandibles truncate at tips, 3-dentate, the teeth acute, the outer 

 slightly longer than the others. 



Thoiax subovate, tlie pvothorax short, narrowed an<l margined an- 

 teriorly, the sides oblique, impressed; mesonotum usually smooth and 

 without distinct furrows; metathorax at least as long as wide, rugose, 

 rounded posteriorly. 



Front wings with a large ovate stigma, two basal cells and a stigmal 

 vein; other cells obliterated. 



Abdomen ovate or oblong-oval, subpetiolat*?, the secoml segment the 

 largest, the others gradually subequal. 



Legs moderate, the fenuua swollen or obdavate, tlie anterior tarsi 

 in 9 du'late. 



A genus usually confused with Chelofjyuus and I>rijinus, but quite 

 distinct. It has not a particle of resemblance to Dryinus, except in the 

 anterior tarsi being chelate. The shape of the head, the short collar, 

 and ovate stigma in front wing, readily separate it from that genus. 

 With Chclofjynus, however, there is a closer reseujblance, but the prono- 

 tum is always nnicu shorter, often only visible from above as a slight 

 collar, while the maxillary i)alpiare 4-jointed. In Cheloijynus the pro- 

 uotnm is always as long, or nearly as long, as the mesonotum, while 

 the maxillary ])alpi are 5-jointed. 



The species are numerous, although nothing i>ositively is known of 

 their habits.
