270 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



Larva. — Body much compressed ; head not so wide as the body, compressed, flat- 

 tened in front, elevated towards the vertex, cleft, ending in two rounded conical tu- 

 bercles; pale rust-red, densely marbled with a fine net- work of darker lines. Body 

 pale rust-red, with a pale pea-green patch on the side of the second and third tho- 

 racic segments, not reaching to the anterior spiracle. First abdomiual segment with 

 a large high acute conical tubercle, bearing at tip two very slender spreading brown 

 cylindrical tubercles. On fifth a slight hump, bearing two small warts ; eighth seg- 

 ment bearing a rather large dorsal hump, supporting two dark warts; in front is a 

 broken V-shaped silver mark, the apex directed forward. Anal legs brown, held, out, 

 with end of body, horizontally. Three lateral obscure oblique lines connecting with 

 a dark obscure lateral straight line placed some distance above the spiracles. Feet 

 all rust reddish, thoracic feet paler. Length 20"*"^ 



Moth. — Fore wings light brown, with patches of greenish white and with wavy 

 dark brown lines, two of which inclose a small whitish space near the shoulders ; a 

 short blackish mark near the middle ; the tip and outer hind margin whitish, tinged 

 with red in the males ; and near the outer hind angle there are one small white and 

 two black dashes ; the hind wings of the male are dirty white, with a dusky spot on 

 the inner hind angle ; those of the female are sometimes entirely dusky ; the body is 

 brownish, and there are two narrow black bands across the fore part of the thorax. 

 The wings expand from one inch and a quarter to one inch and a half, or nearly. 

 (Harris.) It differs from the other species of the genus in having on the thorax dark 

 transverse lines before and behind, with the internal angle of the hind wings dark. 

 In this genus the antenn* are pectinated to the tip, the palpi are short; fore wings 

 rather broad, square at the apex, the outer margin hardly oblique, and the anal tuft 

 is bifid. 



40. Lochmwus sp, 



A notodoutian described below occurred on the elm August 22. I 

 tried iu vaiu to rear it; it began to make its cocoon September 20, but 

 died. 



Larva. — Young. Body rather slender, somewhat compressed. Head rather large, 

 produced toward the apex, but not conical, green ; on each side a white straight line 

 edged iu front with black. On first abdominal segment a pair of bright red 

 dorsal tubercles, third segment from the end of the body humped, the hump ending 

 in two rounded bead-like, reddish tubercles. Anal legs rather large, oblique, but not 

 strikingly so, and not held out straight as in N. unicornis. Body pale green, color of 

 the under side of the elm leaf. Three yellow dorsal lines, the median the narrowest, 

 on the abdomen. On thoracic segments a broad single white line, containing two 

 parallel dark distinct purple thread-like lines; 2 to 4 small yellow warts on each 

 segment. Anal legs with a dark external line. Length 12™™. 



41. Gluphiaia trilineata Pack. 



We have but a single eastern species of this genus to which possibly 

 the QlupMsia% ulmi of Harris' Correspondence (p. 302) belongs. It 

 is represented on his PI. II, Figs. 2-3. He states that the caterpillar 

 inhabits the American elm, occurring in August, September, and Octo- 

 ber. We add his description of the caterpillar, which, however, may 

 possibly be that of Lochmcens manteo., as Harris' figure very closely 

 represents that caterpillar, though he undoubtedly bred this Gluphisia 

 from the elm. 



Larva. — Green, back paler. Head with a white lateral stripe edged before with ver- 

 milion and black ; a reversed black V on the front ; side of the body with minute black 

 points and very short longitudinal lines. A white lateral line converging on the fourth
