lobe itself, there being three of these elongated bristles on the 

 dorsal lobe and one on the ventral lobe, it being directed caudad. 

 In the S the abdomen ends in a blunt, rounded lobe deeply 

 divided into two parts, strongly suggestive of the powerful 

 h^ioopygium of the adult male of this species. Total length of 

 the S pupa, 10-12 mm. 



PUPA, 9 



Differs from the pupa of the same sex of E. longicornis 

 (q. V.) in the following essentials : 



The general form is much stouter and the body is covered 

 with numerous appressed hairs. The sharp spine on the scape 

 of the antennfe is lacking; the lobes of the cephalic crest are 

 small (see plate II, F, b; plate III, C) and tend to converge 

 when viewed from beneath, and are covered with small, rounded 

 warts or tubercles; in front, above the base of the antennae, 

 are two more large lobes so that the crest is four-lobed instead 

 of bi-lobed as in longicornis; these anterior lobes are smaller, 

 rounded, and usually end in an apical tip or spur directed ven- 

 trad. The pronotal breathing horns (plate II, F, a) are very 

 long and rather slender; the mesonotum more convex than in 

 longicornis; the wing-pad usually shows the venation clearly on 

 the pale background and the presence of crossvein r connecting 

 Ri with R2+3 is distinctive of this species; the absence of cell 

 Ml separates this pupa from E. hracliyccra 0. S., spinosa 0. S., 

 et al. The leg-sheaths end almost on a level, the outer or hind 

 pair being but a trifle longer than the two inner pair. The 

 spicules on the caudal margin of the abdominal segments are 

 smaller and more numerous, on some of the segments (tifth and 

 sixth tergites) averaging forty. The ninth abdominal segment 

 (plate III, G) is much longer than in longicornis, the ninth 

 tergite elongate, pointed, much longer than the ninth sternite 

 and scarcely directed dorsad, being much more like a typical 

 ovipositor than in longicornis. 



Fully colored pupa? are dark brown, the cephalic crest being 

 paler, the pronotal breathing horn is pale yellow, darkening 

 into brown at the tip. The wing-pads are light yellow with the
