Length, 13 mm. Whitish testaceous, slightly shining, cephalic and 

 abdominal thorns dark brown. Head with six strong thorns, the upper 

 4 stout, the lower central pair more slender and shorter; the hairs above 

 bases of thorns stronger than normal ; lateral view of head as in Figure 

 14, anterior view as in Figure 13 ; basal section of sheath of mouth parts 

 (labrum) with a bifid thorn near apex. Thoracic spiracle distinct, its 

 margin formed of small bead-like swellings, the open side (i. e. the break 

 in circle) directed backward ; discal hairs on thorax long and strong, 4 

 in number and in the normal positions; wing with a small subcostal 

 protuberance about one-third from base ; wings extending to middle of 

 second ventral abdominal segment; mid legs extending beyond wings as 

 far as apex of fourth tarsal joint ; hind legs extending beyond wings as 

 far as apex of second tarsal joint ; the tip of tarsi reaching to apex of 

 fourth ventral segment; surface of thorax smooth. Abdomen with 

 spiracles well defined, similar in form to those of thorax, the open side 

 directed forward; first dorsal segment with 6 long bent hairs on each 

 side of disc, the central portion without short thorns ; transverse armature 

 of second dorsal segment consisting of rather closely placed, short, stout 

 thorns which are reflexed at apices, do not extend to lateral margins 

 and, except in central portion, are interspersed with long fine hairs which 

 are carried to lateral margin; thorns progressively weaker and more 

 widely placed on the following segments, and the hairs more numerous 

 and rather longer until on the seventh segment they alternate witli the 

 thorns; eighth segment with 3 short thorns and 4 long hairs; lateral 

 margin (post-spiracular) of first segment with 7-8 long stout hairs, those

The specimens from w^hich the description is drawn was sent me by 

 Mr. Otto Swezey. It was obtained at Urbana, 111., April 25, 1914, by Mr. 

 G. N, Wolcott, at which time it was still inside of the cocoon of Elis 

 sexcincta, a primary parasite of Phyllophaga { Lachnosterna) spp. Mr. 

 Swezey has recorded the occurrence of fulvohirta as a secondary parasite 

 on Elis. The species is common throughout the greater portion of the 

 United States and is represented in the collection here by specimens from 

 the following Illinois localities: Havana, Dubois, St. Francisville, Mere- 

 dosia, Topeka, Muncie, Jonesboro, Quincy, Pekin and Metropolis. The 

 dates range from the beginning of August till September 19. There is
