where they suddenly end opposite the base of the movable hook. Three 

 scars (areas destitute of the general scurtiness of the skin) upon the 

 rear of the head, with a low transverse ridoc on the wnv of tlic head 

 behind them. 



Prothorax depressed, with a pair of large dorsal scars. Legs siiort; 

 burrowing hooks of the fore and middle tibia^ well developed; tarsi 

 2:2:8-jointed; femora and tibia' with lateral bare lines, and latei-al- 

 fringes of long hair on their edges. Wing cases reach the middle 

 of the fourth abdominal segment. 



Abdomen bare: segments about ecjual in K'ngtii as far as tiic niiuh, 

 the tenth triquetral, twice as long as the ninth; appendages almost as 

 long as the ninth segment; equal. Dorsal hooks on segments 2-9, 

 pointed on 2 and 8, obtuse on -1—7, pointed on S and !>, and longest on i). 

 Lateral spines on segments 8 and it short, divei-gent. Proinint'iit lat- 

 eral scars on segments 3-9. 



A single full-grown specimen, taken at the l)eginning ol' transforma- 

 tion and pinned. It is a highly interesting form, ver^' distinct from 

 all that haAc been described hitherto. I have referred it to PhijlJo- 

 go))ij)hus because its size and its locality allow this, and especially 

 because I have been able to observe what are practically the a(hilt 

 structures in wings and antennte, and these correspond very well. 

 Unfortunately 1 have not seen the adult PhijUogoiupJnis^ and have been 

 obliged to make my comparisons with the printed statements— not 

 very detailed — of published descriptions. By removing the wings of 

 one side from their loosened sheaths, softening them, and then spread- 

 ing them out — an exceedingly delicate and tedious operation — I have 

 been able to make out enough of the details of the venation of the 

 adult to admit of settling the question of the correctness of the generic 

 reference, at least, b}' anyone who has the adult l^fn/n(><i(iiiij>lnis for 

 comparison. 



Ante and post nodals are in the fore wing IT and 13. and in the hind 

 wing 12 and 16, respectively. The triangles and supertriangles are 

 free from cross veins. The triangle of the fore wMng is followed by 

 3:3:2:3:2:3 and then an increasing number of cells; of the hind wing, 

 by 1:2:2:2:2:3:3:3:3 and then an increasing luunber. The bridge is 

 long and there are in both wings four included cross veins between 

 the subnodus and the ol)lique vein, and about three others included 

 before the subnodus. The stigma has a brace vein at its imier end, 

 and covers five cross veins besides (shown clearly only in hind wing of 

 this specimen). In the fore wing there are eleven unbisected cells in 

 the fork of veins Mi and ]\I.,. There appear to be three medio-cubjtal 

 cross veins before the triangle in the fore wing, and two in the hind 

 wing, and the cubitus seems to run to the hind angle of the triangle 

 without })eing angulated in either wing. There is no anal loop, veins 

 Ai and A. being rather wide ai)art at base with two cells between
