Pyrilloxenos compactus new species. 



Described from a type female, and allotype male, and two 

 paratype females from Pusa, Behar, India, collected by C. S. 

 Misra. 



The material was collected in August, 1907, March 15, 1913 and 

 May 23, 1914. The host is an undetermined species of Pyrilla. 

 The specimens collected in August, 1907 consist of allotype male, 

 male pupa cephalotheca, and three paratype females with tri- 

 ungulinids. This material is the property of the Entomological 

 Section, Agricultural Research Institute, Pusa. The type is 

 deposited in the United States National Museum, and a paratype 

 female is in the author's collection. The author is indebted to 

 Mr. T. Bainbridge Fletcher, Imperial Entomologist, for the 

 material. The specific name is intended to draw attention to the 

 compact appearance of the antennae. 



Male: Length 1.5 mm. The tarsi are very small. The anterior tibiae 

 are very robust and shorter than on the other legs. The antennae are 

 much more compact than is usual in this family. The mandibles can not 

 meet. The remainder of the description is to be drawn from the generic 

 description. The specimen was unfortunately boiled in caustic potash 

 and is therefore very hard to study. 



Female: Cephalothorax, golden yellow to brownish, broader than long; 

 constricted behind spiracles; sides quite evenly rounded; apex sinuate. 

 Mandibles obtuse, separated by almost three times their width. Front 

 convex. Spiracles just touching margin. 



Type in U. S. Nat. Mus. Cat. No. 18814. 



A NEW TACHINID PARASITE OF DIAPHEROMERA 

 FEMORATA SAY. 



BY W. R. WALTON, Bureau of Entomology. 



Two species of Tachinidse parasitic upon the Phasmidse are 

 at present known to science. The first species was described by 

 Pantel 1 in 1898 as having been reared from Leptynia hispanica 

 Bal. in Europe. The second has been recently described by Mr. 

 C. H. T. Townsend 2 reared by the brothers Severin from Diaphero- 

 mera femorata Say. in Wisconsin. A third parasite of this same 

 host is herewith described. It is generic-ally closely related to 

 Hallidaya Egger, but is apparently distinct because of the posi- 

 tion of the antenna above the center of the eye and of the greater
