736 MR. R. E. TURNER ON 



at the extreme apex only ; second abscissa of the radius twice as 

 long as the first and about equal in length to the third ; second 

 cubital cell receiving both recurrent nervures, the first at one- 

 third from the base, the second just before the apex ; third 

 cubital cell as long on the radius as on the cubitus. Tarsal 

 ungues bifid ; lobe beneath the apical half of the hind femora 

 strongly rounded ; basal joint of hind tarsi with a row of short 

 hairs beneath, in which are a few longer spines. Closely punc- 

 tured ; the thorax very closely and finely punctured, with larger 

 and sparser punctures intermixed ; abdomen shining and sparsely 

 punctured. 



Black, with whitish pubescence ; sixth dorsal segment densely 

 clothed with long golden hairs ; clypeus except at the apex and 

 the margins of the eyes broadly interrupted on the summit, 

 yellow ; basal two-thirds of dorsal segments 2-4 and of ventral 

 segments 2-3 emarginate in the middle posteriorly, rufo- 

 testaceous. Wings subhyaline, nervures fusco-ferruginous. 



Length 22 mm.

An obscure scar runs from the base of the stigma to close to 

 the base of tlie first transverse cubital nervure. I have little 

 doubt that the male of this species will prove to be ^. crassicornis 

 Sm., which corresponds with it in the position of the recurrent 

 nervures, the bifid tarsal ungues, and also to some extent in the 

 colour of the clypeus and abdomen,

I fail to recognise this species with any certainty, but do not 

 consider that the subgenus Colohosila can stand, the truncation 

 of the apex of the radial cell being insufficient as a subgeneric 

 character unless supported by others.

I do not recognise this species as a synonym of aiiy known to 

 me, though it seems to be related to A. anthracina, difl[ering in 

 the position of the first recurrent nervure. Considei-ing how 

 imreliable the details of neuration are in this genus, it is quite 

 possible that it is only a variety of anthracina.

5 . From the description I have no doubt that this is a,n 



Anthohosca, the characters " apex of radial cell sharply pointed," 



and " pygidium piceous red, its base fringed with long, bright 



rufous hair," and " metapieurse smooth," agreeing much better
