PSYCHE. 



costal spine, grayish-hyaline, opaque gray at 

 base; apical cell very narrowly open at some 

 distance before the apex of the wing; fourth 

 vein bent at an angle without stump or 

 wrinkle, the bend not sharp, apical cross- 

 vein a little concave ; hind cross-vein curved, 

 nearer to bend of fourth vein; third vein 

 spined at base; tegulae white, halteres yel- 

 lowish grav. 



§ . Differs as follows : Front nearly one- 

 half the width of head; frontal vitta broad, 

 occupying one-third of frontal width ; three 

 orbital bristles (on one side, on the other 

 side only two) ; eyes more distinctly hairy, 

 especially on upper portions; claws and 

 pulvilli hardly shorter. 



Length of $ 6 mm.; wing 5^ mm. $ 

 7 mm. ; wing 6 mm. 



Described from three $ specimens, 

 and one 9 ■> bred from chrysalids of 



Hyphantria cunea, Las Cruces, New- 

 Mexico. This species is best located in 

 Meigenia. The face, however, is not 

 almost perpendicular, the abdomen is 

 short and stout, and the macrochaetae 

 are only marginal unless on the anal 

 segment. It cannot be referred to 

 Mystacella, which has the eyes more 

 decidedly hairy. 



Note on Phorocera promiscua Towns. 

 Psyche, v. 6, 84. This species was wrongly 

 referred to Phorocera, my reason for the ref- 

 erence being that the facial ridges are bristly 

 for fully half their extent. But the eyes are 

 very indistinctly hairy, the species agreeing 

 in this and its other characters with Mei- 

 genia. It will be best, I believe, to refer to 

 it as Meigenia promiscua Towns. 



NOTES ON BOMBYCID LARVAE.— III.

Schizura eximia Grote.

I have for some time considered this spe- 

 cies improperly referred to Oedemasia, but I 

 have never found the larva. Dr. Thaxter, 

 however, has bred it, and writes me as fol- 

 lows : " Oedemasia eximia resembles Coelo- 

 dasys leptinoides* in coloring, but structur- 

 ally is perhaps more like biguttatus (ipo- 

 meae). When at rest it is greatly hunched 

 anteriorly, and the furcate prominence on 

 segm. 4 is very long. I should say it was 

 surely a Coelodasys" ( = Sc/iizura). 



I would place it next to 5. leptinoides and 

 near Ianassa.

Larva. I have found this larva on Vibur- 

 num lentago, and it is certainly not an Oede- 

 masia. It is without the red hump and black 

 tubercules of O. concinna, the body being 

 smooth, with dorsal processes on the 1st, 

 4th, and 8th abdominal segments; the sides 

 of the thoracic segments are green, but the 

 usual V-shaped mark is, I believe, absent. I 

 have not been able to obtain the larva re- 

 cently for more careful description.

Larva. Third stage. Head black, with a 

 few short hairs; cervical shield bisected, 

 black, as is the anal plate. Body yellow, 

 with short pale hairs growing from black 

 tubercles; joint 5 has a slight dorsal hump 

 somewhat orange tinted, and with four 

 smooth black tubercles, these being part of a
