118 Mr. Pi. E. Turner on the 



Sauss., and Dimorphoptera, both of which I have treated in 

 former papers as synonyms of Cosila, sinking all three names 

 under Anthobosca. I follow Sicheland Saussure in regarding 

 the group as a link between Myzine and Scolia, though also 

 showing some affinities with the Thynnidae. The other 

 genera placed by Ashmead in the Cosilidse seem to me to be 

 of very doubtful affinities, but I have not seen specimens of 

 Sierolomorpha, Dicrogenium, Nursea, or Isotiphia. Maurd- 

 lus, Sm., seems to me to be rightly placed by Smith in the 

 Pompilida;, the mandibles being the only feature in which 

 it resembles the groups allied to Scolia. Fedtschenkia, like 

 1'terombrus, is a very distinct genus, which does not fall con- 

 veniently into any group, but is probably better placed as a 

 subfamily of the Mutillidae, as is done by Andre*. I have 

 only seen the male, but Ashmead places it with the Cosilidge 

 only because the female is winged. The male agrees with 

 Anthobosca in the total or almost complete absence of the 

 transverse depression between the first and second ventral 

 segments, a character by which Anthobosca may be at once 

 separated from Myzine or Tiphia, as well as in the unarmed 

 hypopygium. The former character is shared with many 

 of the Thynnidse, especially in the female sex. Ashmead's 

 key to the classification of his family Myzinidse (' Canadian 

 Entomologist/ 1903) is very confused, the characters for 

 the females being in several cases given under the heading 

 " males." He is, however, probably correct in placing 

 Poecilotiphia, Cam., in the family. 



Tiphia coni]>ressa, Sm. 



? . The type is from China; Indian specimens have the 

 anterior wings fusco-violaceous y and the intermediate and 

 posterior femora and trochanters wholly ferruginous ; there 

 is also an oblique carina on each side on the dorsal surface 

 of the median segment, reaching from the base, where it is 

 about as far from the outer of the central carinse as that 

 is from the median carina, to within a short distance of the 

 apical angle of the segment ; this carina is only faintly 

 indicated in the type. 



£ . Clypeus rather finely and closely punctured, shallowly 

 and broadly emarginate at the apex ; head shining, the front 

 closely and rather finely, the vertex and the space round the 

 ocelli very sparsely punctured ; the scape finely and closely 

 punctured, with a few rather short, pale fulvous hairs beneath. 

 Pronotum shining, sparsely and rather finely punctured, the 

 posterior margin broadly smooth; the propleuraj smooth and
