joint the longest, clavate, the second about twice as long- as thick, 

 stouter than the hist but shorter; maxillary palpi long-, apparently 

 4 jointed, the joints long, sul)equal in length, the second dilated into 

 a compressed, obtusely triangular lobe beneath toward apex, the 

 other joints cylindrical; antenn;e tapering otf toward apex, apparently 

 3T-joiutcd, with a broad white annulus at the middle, the scape rather 

 h)ng and stout, about foar times as long as thick; the mesonotum is 

 without a trace of the parapsidal furrows; the scutellum is subconvex 

 and delicately keeled at the lateral margins; the metanotum is areo- 

 lated, the areola being hexagonal, longer than wide, the spiracles 

 elongate; the abdomen is subcompressed toward apex, with a dis- 

 tinctly projecting ov^ipositor, although short, as in some Oryptines; 

 the second segment alone is distinctly punctate, the others being 

 smooth and shining, the gastrocoeli being large and transverse; the 

 venation of the wings is very similar to that in Ichneumon^ the areolet 

 being pentagonal, the median and submedian cells equal, the trans- 

 Averse median nervure being distinctl}^ interstitial with the basal nerv- 

 urc; in the hind wings the transverse median nervure is straight but 

 broken by the suljdiscoidal nervure far helovj its middle. 



15. ELASMOGNATHUS CEPHALOTES, new species. 



Female. — Length 0.5 nnn. ; ovipositor projecting consideral)ly 

 beyond the tip of the al)domen, or the length of the second joint of 

 the hind tarsus. Black marked with yellowish white as follows: An 

 oval spot on vertex back of ej'^es, the upper inner orbits, the hind 

 orbits broad I3' for two-thirds the length of the eyes, the cheeks, the 

 face except an oblong black median spot, the mandibles except the 

 teeth, the palpi, the anterior margin of the prothorax, the hind inar- 

 gin of the same to the tegulie, but broadly interrupted at the middle, 

 two short lines on the disk of the mesonotum, the scutellum and post- 

 scutellum, the teguhv, a spot beneath same, a broad band on the mcso- 

 pleura, a spot at the insertion of the hind wings, a spot on each side 

 at base of the metathorax inclosing the spiracles, a spot back of these 

 on the hind angles and connected with a large (quadrangular spot on 

 the upper hind angles of the metapleura, the basal hidf or more of 

 the abdominal petiole, the apical margin of same, the basiil margin of 

 the second segment including the gastroccjeli, and the apical margins 

 of segments 2 to 7, most of the ventral membrane, except some 

 lateral spots and the last two segments basalh", the front and middle 

 coxaa and trochanters, the hind coxa> broadly at apex, and the hind 

 tarsi except pulvilli and the basal half of the first joint, all white or 

 yellowish white, the scutellum ])eing more distinctly yellow; rest of 

 the legs, except as noted, mostly red; the hind coxfe basally, the hind 

 trochanters, except a white spot above, a stain at apex of hind femora 

 above, the base of hind tibiic, the basal half of the first joint of hind
