Catocala irene Behr. 



Ovum. Similar to that of C. californica and faustina. 



Stage I. Scarcely to be distinguished from faustina; head pale red-brown; body 

 greenish-gray shading into purplish laterally with three pale lines of ground color. 

 Length, 5 mm. 



Stage II. Head whitish, marbled with blackish stripes, with slight tinge of 

 orange apically. Body pale gray-green, laterally greenish-black with three pale 

 waved stripes; a faint dorsal stripe with diamond-shaped enlargements. Length, 

 11 mm. 



Stage III. Head pale with brown marbling, shaded with orange at apex and 

 with black lateral border-lines not meeting dorsally. Body light olive-brown with 

 pale dorsal and lateral stripes as before bordered with deep brown, the lower border 

 of stripe II and the upper one of III especially prominent; transverse wart on 

 5th abdominal segment reddish with ochreous apex; below the wart a black- 

 brown lateral shade broken by the pale stripes, deepest in color above stripe III 

 and tending to extend along its dorsal margin towards anal segment; dorsal tuber- 

 cles orange, larger and conical on 8th abdominal segment with slight black lunate 

 marks behind them not meeting dorsally. Length, 17 mm. 



Food-plant: Willow. 



We were unsuccessful in bringing the larvae to maturity. They 

 are evidently also allied closely to faustina. 



THE DISTRIBUTION OF SOME SPECIES OF 

 DROSOPHILA. 



By Charles W. Johnson,

In making a careful faunal survey of any given area, covering 

 a number of years, the gradual or sudden appearance of a species 

 common in other sections, is often of greater importance from the 

 standpoint of geographical distribution than the capture of a num- 

 ber of rare species, often widely distributed, but of whose life his- 

 tory or of the factors governing their distribution little is known. 



During the early fall, while experimenting with various species 

 of fungi in an effort to breed some Platypezidse, my attention was 

 called to several dark colored flies which alighted repeatedly on 

 the netting of many of the jars containing decayed fungi. On 

 capturing several of these I was surprised to see Drosophila repleta 

 Woll. (D. punctata Loew), the first I had seen in Boston. I had
