GIO Mr. R. E. Turner on Fossorial Hymenoptera. 



$. Testacea ; tliorace fusco-brunneo ; capite fusco, liaud com- 

 presso, latitudiue pauUo longiore, subconvexo, nitido ; pronoto 

 longitudiae sesqui latiore ; segmcnto dorsali secundo transverse 

 tricariuato, margine apicali insuper paiillo elevato ; pygidio 

 elongato, aiigusto. 

 Long., S 7 mm., $ 4 mm. 



(^ . Clypeus strongly convex, not elongate, narrowly trun- 

 cate at the apex, much broader than long, produced into a 

 point on each side above the base of the mandibles. Au- 

 tenuse shorter than the thorax "without the median segment, 

 inserted further from each other than from the eyes, without 

 an interantennal prominence; the front marked with a 

 shallow- longitudinal sulcus. Anterior margin of the pro- 

 notum strongly raised and transverse ; scutellum rather 

 narrowly truncate at the apex, only slightly convex ; median 

 segment rounded ; abdomen slender, the sides almost parallel 

 except at the extremities ; the segments constricted at the 

 base ; sixth ventral segment with a short spine on each side 

 at the apical angles ; hypopygiura not broad, ending in three 

 spines, the middle spine more than twice as long as the 

 lateral. Very sparsely and rather finely punctured, the 

 abdomen almost entirely smooth. Third abscissa of the 

 radius longer than the second ; the second recurrent nervure 

 received at about one-sixth from the base of the third 

 cubital cell. 



? . Smooth and shining, with a few small punctures on 

 the abdomen. Head subrectangular, rounded at the poste- 

 rior angles, a little longer than broad, a lateral carina 

 reaching from the eye nearly halfway to the posterior margin 

 of the head, the sides of the head concave. Pronotura 

 slightly narrowed posteriorly, half as broad again as long ; 

 scutellum transverse, not very narrow, more than twice as 

 broad as long, equal in length to the dorsal surface of the 

 median segment. First dorsal segment broadly depressed 

 at the apex ; second with three transverse carin-ie in addition 

 to the raised apical margin, the basal carina sometimes con- 

 cealed by the first segment; third and fourth segments 

 broadly depressed on the apical margin, the raised portion 

 before the depression deeply emarginate in the middle and 

 rounded at the sides. Pygidium long and narrow, almost 

 linear. 



Hab. Kuranda, Queensland (F. P. Dodd). 



This is very near perele(/ans, Sm., which is probably 

 distinct from cerceroides, but which is at present only known 

 in the male sex. The punctures on the thorax in pcrelerjnns 

 arc very large and deep.
