 Alae hyalinse stigmate fusco, nervis pallidioribus, ultra stigma fere 

 deletis ; areola radialis subcultriformis, radio vix nisi recto. Abdo- 

 men depressum, tliorace brevius, ovatura, lateribus rotundatis ; 

 segmentum lum latitudine sua apicali paulo longius, apice quam 

 basi sesquilatius aciculatum, carinis 2 longitudinalibus ante mar- 

 ginem posticum obsoletis, basi ipsa testaceum, tuberculis fere 

 inconspicuis ; caetera laevia, nitida ; segmentum 2um lo haud 

 brevius, postice latius ; Sum quadruple brevius ; sequentia exserta^ 

 3o non breviora sed latitudine sensim decrescentia ; 7um subito

Black, shining, abdomen sometimes inclining to piceous ; legs 

 pale testaceous, including the coxae ; hind tibiae and tarsi dusky, 

 except the base of the former ; 4 anterior tarsi dusky at the tips. 

 Antennae 3' longer than the body, entirely black, 27-jointed. Palpi 

 pale. Prothorax punctulate, shining. Mesothoracic sutures im- 

 punctate. Metathorax inclined from the base, not truncate behind, 

 indistinctly areated, shining. Wings hyaline, stigma fuscous, 

 nervures paler, nearly effaced beyond the stigma ; radial areolet 

 subcultriform, radius almost straight. Abdomen shorter than the 

 thorax, depressed, ovate, with rounded sides ; 1st segment rather 

 longer than its apical width, which is only one-half greater than 

 that of the base, aciculated, with 2 longitudinal carinae, effaced 

 before the hind margin ; the extreme base testaceous ; tubercles 

 indistinctly prominent ; the remaining segments smooth and 

 shining ; 2d segment as long as the 1st, widest behind ; 3d only a 

 quarter as long ; 4th — 7th exserted, as long as the 3d and succes-

Described from 3 males in Fitch's collection, which 

 are there named claviventris, Euthe ; that author, how- 

 ever, describes only the ? , and says nothing about the 

 exsertion of the posterior segments, unusual in the 

 genus, and which may or may not be a characteristic of 

 the (? in this species. C. exsertor, Euthe, has the pos- 

 terior segments conspicuous in both sexes, but the 

 present insects cannot be referred to that species, the 

 1st segment of which is shorter than its apical width.
