directed spine on each posterior dorso-lateral angle, and a small wart- 

 like process about midway between the base of that and the ventral 

 line (Figs, i and 3). 



The specimens from which the above description was drawn are 

 two empty pupa skins obtained by Mr. Hart at Beach, 111., August 24, 

 1906. It is not certain that the pupa is that of milberti, as the species 

 was not reared, but imagines were obtained at the same time and place, 

 and as this was the only species of such large size that was found I 

 assume that the pupa very probably belongs to it. 



The species is very probably predaceous in the larval stage upon 

 larvae of burrowing insects.

Pupa (PI. LXXXI, Fig. 7). — Length, 12 mm. Brownish yellow, 

 slightly shining. Head distinctly shining, integument without distinct 

 wrinkles ; a pair of strong thornlike projections on anterior cephalic 

 surface (Fig. 6) which are rather irregularly longitudinally rugose at 

 base, smooth and highly polished at apices; on each side of the head, 

 almost in vertical line with these thorns and located on the latero- 

 ventral region there is a tridentate process of a similar nature to the 

 thorns (PI. LXXXII, Fig. 18), the posterior one having a slight scale- 

 like process near its base. Thorax with faint indications of wrinkling 

 on the surface and 3 wartlike projections on each side (as shown in PI. 

 LXXXI, Fig. 7), the lower one, at base of sheath of posterior leg, hav- 

 ing 2 distinct sharp thorns at the apex (PI. LXXXII, Fig. 17). Abdo- 

 men with surface of all segments wrinkled; first segment with 10 long 

 upright brown thorns (PI. LXXXI, Fig. 7), the apices of which are 

 directed slightly backward, near the anterior margin on dorsum, the dis- 

 tance from the central one to the outer one being about equal to the dis- 

 tance from the latter to the spiracle ; posterior to the spiracle are 3 long 

 fine hairs, otherwise the segment is bare; second to sixth segments each 

 with a transverse median row of stout brown thorns alternating large 

 and small in size, extending from median line midway to spiracle on 

 each side, being replaced at this point by a series of long fine hairs 

 which are carried below the level of the spiracles and almost join the 

 ventral series ; seventh segment with the dorsal series located nearer to
