9, very minute on the former ; otherwise the lateral margins are 

 smooth and free from hair. Dorsal surface of abdomen as far as base of 

 segment 6 evenly convex from side to side with a very faint median ridge, 

 along which is a faintly impressed line ; beyond this the ridge is some- 

 what more distinct and the sides slope more abruptly. The " scars," or 

 irregular bare patches, on the dorsal surface of the abdomen are con- 

 spicuously marked on segment 1-8, and are represented on 9 by a pair of 

 distinctly impressed lines. Width of metathorax about equal to that of 

 the first abdominal segment. Wing-cases extending 

 a little over the base of the fourth abdominal segment. 

 Legs thinly fringed on both anterior and posterior 

 margins with rather long hairs, except the posterior 

 margins of all the tibise, which bear a rather dense 

 fringe. Antennfe with the third joint about one- 

 third longer than the first and second joints together, 

 slightly broader at apex than at base. Mentum of 

 labium about one-third longer than broad and a 

 little more than two-thirds as broad at base as at apex, 

 contracted in its basal two-fifths. Median lobe 

 distinctly produced, the anterior border convex 

 and bearing on its margin a dense fringe of short flat, light brownish 

 hairs, in the midst of which at the apex is a pair of very small, shining, 

 dark brown teeth, which are seen with some difficulty. Lateral lobes 

 with the outer margins very convex, apex with a prominent hook and about 

 six other nearly equidistant teeth along the inner margin, the basal one 

 very small, the others prominent and of about equal size. 



Total length, 33 mm.; abdomen, 22.5 mm.; hind femur, 6 mm.; 

 width of head, 5.75 mm.; of abdomen, 7 mm.

NOTE ON HAPLOA CONTIGLTA, WALK. 



When I was working on the Haploas, previous to the publication of 

 my paper on "The North American Callimorphas" (Can. Ent., XIX , 181- 

 191), I appealed to Mr. A. G. Butler for information in regard to Walker's 

 types, and he very kindly sent me sketches of the types of Contlgua and 

 Confiiiis as then standing in the British Museum collection, but as what 

 was shown as the former was practically the same as the latter, I wrote 

 that I thought there must be some mistake, and sent a drawing of what 

 we, in this country, understood to be Contigua. Mr. Butler, in replying,
