Hymenoptera in the British Museum. 83 



differs in the colouring, especially of the legs, from the 

 alHed species. The infuscation of the wings is caused by 

 numerous small hairs. 



SubfamUy CRABRONINAE. 



Entomognathus rugosissimus, sp. n. 



?. Nigra; abdomine pedibusque ferrugineis; coxis anticis, tro- 

 chanteribus anticis, femoribusque anticis subtus nigris; tegulis 

 testaceis ; alis fuscis, venis nigris ; clypeo argenteo-pubescente. 



Long. 8 mm. 



?. Mandibles deeply excised on the outer margin, simple at the 

 apex. Cljrpeus raised into a porrect tubercle just above the middle 

 of the apical margin, with a very short blunt tooth on each side 

 near the apical angles. Eyes hairy, the facets in front rather 

 larger than elsewhere. Head large, but not broader than the 

 thorax ; front broad, the eyes separated at the base of the clypeus 

 by a distance equal to the length of the scape; antennae short 

 and stout, the third joint of the flagellum as long as the second ; 

 ocellar region and vertex very coarsely punctured ; ocelli in a very 

 broad triangle, the posterior pair far apart, but nearly as far from 

 the eyes as from each other, an irregular oblique groove from each 

 posterior ocellus reaching almost to the eye. Pronotum trans- 

 verse, rounded at the angles, punctured; mesonotum coarsely 

 punctured-rugose; scutellum with sparse large pimctures; meso- 

 pleurae coarsely, but rather sparsely, punctured, with a smooth 

 groove in front for the reception of the anterior femora. Median 

 segment very short, the dorsal surface only half as long as the 

 scutellum; the basal area very broadly rounded at the apex, 

 with several strong longitudinal carinae; the posterior slope 

 abrupt, almost smooth, with a broad shallow median groove narrow- 

 ing towards the apex. Abdomen sessile, the basal segment the 

 broadest, the two basal dorsal segments with sparse, but rather 

 large, punctures; the remaining segments with small scattered 

 punctiires ; sixth dorsal segment rather narrowly triangular, clothed 

 with golden pubescence. Hind tibiae hairy, almost miarmed, with 

 feeble serrations near the apex; fore tarsi unarmed. Recurrent 

 nervure received at three-quarters from the base of the cubital cell; 

 radial cell broadly truncate at the apex, the transverse cubital 

 nervure received at the middle of the radial cell.

This is very distinct in colour and sculpture from other 

 species of the genus, but does not differ much in structural 

 characters.
