inner margin, half-way from the base ; the secondaries are black, like the 

 primaries, and are traversed from just before the outer angle by a broad 

 orange band, which diminishes regularly to the inner margin, on which 

 it terminates ; the fringes are narrowly white interrupted with blackish. 

 On the underside the primaries are dark fuscous, with the inner margin 

 obscure stramineous ; the spots of the upperside reappear, and, in addi- 

 tion, there are a number of minute yellowish spots upon the costal and 

 outer margins, and two or three sabapical spots; there are also some small 

 spots upon the cell, both before and behind the central orange spot, which 

 appears upon the upper surface. The ground color of the secondaries is 

 as that of the primaries ; the broad orange band of the upper surface is 

 reduced and does not extend to the inner margin, as on the upperside, 

 and is much indented externally; there are nine or ten small orange spots 

 on the basal third, a relatively large orange spot on the costa near the 

 middle, and a marginal and anal series of yellow spots of varying size, 

 those of the marginal series, near the outer angle being the largest. The 

 fringes on the underside are narrowly white, broadly interrupted with 

 blackish at the end of the nervules. The antennae are black annulated 

 with white on the lowerside. The upperside of the body is black, the 

 lowerside fuscous. The legs are black, with the tarsi annulated with 

 whitish. Expanse 27 mm. 



Hab. Bule Country, Cameroons (Good). I have named this 

 curiously marked species, which is totally unlike any other in 

 the genus, because of its somewhat mimetic likeness to the Hes- 

 peridae of the Galenus group. The only species which at all 

 resembles it is T. adelgunda Kirby- The type is unique.

ON THE LARVAE OF HYDROCHARIS OBTUSATUS AND 

 SILPHA SURINAMENSIS. 



By H. F. WICKHAM, Iowa City, Iowa. 



The larvae of the two above-mentioned species were obtained 

 during a Summer trip to Bayh'eld, Wis., on the shores of Lake 

 Superior. As neither are fully described as yet, notes and figures 

 are appended. 



Hydrocharis obtusatus Say, fig. i. Color of larva, above greenish, head 

 and prothorax chestnut, beneath lighter, form moderately elongate, not 

 very convex, broadest at about the middle of the abdomen. Length of 

 full-grown living specimen, 28 mm. 



Head narrower than the prothorax, sides rounded, more strongly near 

 the base, front impressed each side, elevated at middle, these elevations 

 and impressions extending also to the vertex, occiput with two triangular 

 impressions at the base. Frontal margin obtusely lobed at middle.
