248 Mr. R. E. Turner 07i Fossorial Hymenoptera. 



I think there can be little doubt that these names refer to 

 one Sjjecies. Smith's type was from Trebizond, but there 

 are specimens in the British j^Iuseum from Karachi [E. 

 Comber), Mt. Abu ( jV^wrse), and also in the present collection 

 from (/oimbatore. Tlie specimen marked cassius, collected 

 by Nurse and acquired by P. Cameron, is very much smaller 

 than the usual form, and the striaj on the median segment 

 are less distinct, but: the latter character varies considerably 

 in the larger specimens.

Bingham was wrong in his identification of this species, 

 though it is nearly allied to rejiexus, Sm. In delectus the 

 third cubital is petiolate; in refiexus the third abscissa of the 

 radius is iialf as long as the second ; in detectus the posterior 

 ocelli are quite as far from each other as from the eyes, in 

 reflexus distinctly nearer together. Bingham''s specimens 

 from Tenasserim have i\\e third cubital cell pointed on the 

 radius, not petiolate, and the ocelli as in detectus. Smithy's 

 type is from Sumatra.

 PassaJoecus carinicolUs, Cam. MS. ? 



This species is undoubtedly a Sdgmus. I cannot find that 

 the name Passaloecus carinicoUis has been published, but a 

 specimen bearing that name and marked as the type by 

 Cameron is in the British Museum, where is also the type of 

 marginicollis. The species also occurs at Penang. It is 

 very near S. congruus, Walk., from Ceylon, but the petiole 

 is rather longer in that specie's.
