and legs pale green ; head obovoid, high, the top narrow, on each vertex a long, 

 tapering, conical process or horn, tlie two meeting at base ; whole surface rough 

 with fine tubercles, each with fine, short hair; color yellow-green, the horns 

 red ; down the front of each horn from near the top, a brown stripe, which 

 passes alongside of face to the ocelli, tapering to a line. (Figs, (j natural size, g'^ 

 to g* magnified.) The length of the period from last moult to pupation I am 

 unable to give, but it is probably aboiit ten days. 



Chrysalis. — Length .62 inch; bi-eadth across mesonotum .10, across abdo- 

 men .17 inch; cylindrical, slender; the edges of wing cases prominent; head

 tle at the sides, the top incurved, the corners sharp ; mesonotum prominent, the 

 anterior side forming almost a right angle with the dorsal side, carinated, the 

 sides flat and sloping ; color green ; the top of head case and dorsal edges of

Canthus flies in the northern States from Maine to Wisconsin, at least, and 

 from New Jersey and northern Pennsylvania to Iowa, Nebraska, and Colorado. 

 In the latter State it has been observed only in the northeastern part. Mr. David 

 Bruce writes : " It occurs near Estes Park. This region is of about 5,000 feet 

 elevation, and is well watered by the Big Thompson and Cache la Poudre rivers, 

 and is full of small lakes and reedy flats where many of the small waterfowl 

 breed in numbers. In this locality Canthus flies in abundance. The Colorado 

 examples are of large size, exceeding any eastern ones, the males reaching 2.2 

 inches in expanse of wing, the females 2.4 inches, but they do not differ in other 

 respects from their congeners. 



Until recently, this species has not been reported in the southern States, or 

 south of the Ohio River. But, in Psyche, Vol. V., p. 348, May, 1890, IMr. El- 

 lison A. Smythe, Jr., of Columbia, South Carolina, relates as follows : " While col- 

 lecting Catocalas, in September, 1889, in a thick swamp, in Clarendon Co., S. C, 

 near the Santee River, I came to a spot where a ray of sunlight penetrated the 

 thick foliage far overhead, and there, in the glow, were a great number of Debis 

 Portlandia, having a game of ' hide and seek ' with one another. I stood watch- 

 ing their gambols for some time, mitil I thought that one of their number seemed 

 smaller and otherwise different from the rest ; in a moment he lit close to me, 

 and I saw to my surprise that it was something entirely different, and at the mo- 

 ment I could not place it. That was enough, however, and I started to capture
