the middle of the second cubital cell, the second at two-thirds 

 from the base of the third cubital cell ; radial cell truncate. 



Fusco-ferruginous ; head black, covered with grey pubescence ; 

 abdomen paler than the thorax, a tuft of white pubescence at the 

 apical angles of the second and third segments, the dorsal segments 

 with sparse black pubescence, white on the apical segment. Legs 

 black. Wings hyaline on the basal third, the remainder fuscous ; 

 nervures black. 



Length 13 mm.

Nearly allied to rugicollis Westw., which the female strongly 

 resembles in shape and sculpture ; but the second segment is 

 somewhat broader in proportion. The male is easily distinguished 

 from rugicollis <S by the tubercles at the apical angles of the 

 median segment and the broader second abdominal segment. The 

 colour is also very different in both sexes. The two species both 

 occur in the Condon district. 



Ephutomorpha cocytia, sp. n. 



2 . Black, clothed with long black hairs, the hairs at the apex 

 of the second and third ventral segments greyish ; the four apical 

 ventral segments testaceous brown a,t the base. Mandibles 

 smooth and shining, almost straight, with a small blunt tooth on 

 the inner margin. Head narrower than the thorax, rounded at the 

 posterior angles, strongly narrowed and produced anteriorly, finely 

 punctured rugose with a few longitudinal strife on the front. 

 Scape punctured, clothed with long black pubescence ; flageilum 

 opaque, the two basal joints shining. Thorax very coarsely rugose, 

 transverse on the anterior margin, about twice as long as the 

 width on the anterior margin, slightly widening to before the 

 middle, then gradually narrowing to the posterior margin, which 

 is not more than two-thirds as wide as the anterior. Pleurae 

 shining and almost smooth. Second dorsal segment coarsely 

 rugose ; segments 3-5 punctured, the apical segment without 

 hairs, finely longitudinally striated ; second segment shallowly but 

 rather broadly depressed in the middle. First ventral segment 

 strongly carinated longitudinally ; the second rugose in the 

 middle, punctured at the base and apex, depressed on each side 

 at the base, leaving a low carina in the middle between the 

 depressed spaces, the apical margin very broadly depressed. 



Length 14 mm.

In specimens which have lost some of the pubescence on the head, 

 and the sculpture shows more plainly, there can be seen a carina 

 on each side starting from the antennal tubercle and arching 

 toward the eye, and a short transverse carina at the base of the 

 clypeus. The second joint of the flageilum is nearly half as long
