224 THE ENTOMOLOGIST. 



the four anterior knees testaceous ; the fore tibia3 and tarsi obscure 

 white behind ; the calcaria and the apical segment of the abdomen, 

 clear white ; wings hyaline, a cloud along the transverse basal and 

 transverse median nervure, one in the basal third of the radial cellule, 

 extending into the cubital cellule below, occupying it, except the lower 

 basal corner, and into the upper apex of the discoidal cellule, where 

 it becomes fainter ; and there is a faint cloud in the apex of the 

 wings. (? . Length, 7 mm. 



Covered with a silvery pubescence ; the apex of the clypeus 

 narrowly white, broadly rounded. Hind ocelli separated from each 

 other by a distinctly less distance than they are from the eyes, which 

 converge above where they are separated by about the length of the 

 second and third antennal joints. Palpi black. Apex of pronotum 

 arcuate, narrowly edged with yellow. The second abscissa of radius 

 is about one-fourth shorter than the third ; the first transverse cubital 

 nervure is roundly curved ; the second is straight, obliquely sloped ; 

 the first recurrent nervure is received at the apex of the basal third of 

 the cellule ; the accessory nervure in hind wings is received shortly 

 behind the transverse median. The long spur of the hind tibise is 

 half the length of the metatarsus. 



Bassus hetatorius, Fab., in Cape Colony, — This common 

 British ichneumon I find in the collection of the South African 

 Museum from Cape Town, where it has been taken so far back 

 as 1874. It has now been found in nearly every part of the 

 globe and in many of the islands. It would be interesting to 

 know what its host may be outside Europe. Probably some 

 equally cosmopolitan dipteron.
