one-third longer than the fourth, the fourth joint is, if anything, very shghtly longer 

 than the fifth ; thorax very coarsely punctured, the punctures sparsest on scutellum 

 and deepest on metathorax ; enclosed space on metanotum, with exception of base 

 and laterally, smooth ; tibia- and tarsi strongly spinose, the hind tibia; in addition 

 very strongly serrated ; punctuation of abdomen less coarse than that of the thorax, 

 the posterior margins of dorsal segments 1-5 reflexed, the basal portion of segments 

 2-5 transverse depressed, so that when viewed from the side these segments are 

 seen to be separated by a wide fissure ; ventral segments sparsely punctured, trans- 

 versely swollen in middle ; pygidium elongate-ovate, its surface pustulate. Black, 

 clypeus except anteriorly, sides of face, carina between antennse, scape beneath, an 

 elongate spot on mandibles, spot on summit of cheeks, line on prothorax above, 

 interrupted medially, spot on tegulre, two large spots on scutellum and dorsal abdo- 

 minal segments 2-5, all yellow, that on second segment entire, on the others very 

 widely emarginate anteriorly ; first four or five joints of the flagellum beneath, the 

 apical joint also, tegulre in part and coxte and femora more or less reddish, the 

 tibire and tarsi and the hind trochanters generally yellow, the hind tarsi black ; 

 wings subhyaline, the apical margin with a fuscous baud .vhich also includes the 

 marginal cell, stigma and adjoining nervures reddish ; the liead, thorax and first 

 two abdominal segments are clothed with sparse, pale fuscous, long hair. Length, 

 12-13 mm. 



(^. — Anterior margin of clypeus armed with three teelh, the middle one of 

 which is most prominent ; third joint of the antennit distinctly less than one-third 

 longer than the fourth, the last joint obliquely truncate : head and thorax punc- 

 tured about like the female ; the enclosed space on metanotum with strong radiating 

 ridges ; tibiie and tarsi spinose but not so strongly as the female, the punctures of 

 the abdomen stronger and sparser ; pygidium with very large sparse punctures ; 

 colored like the 9 except that the clypeus is entirely yellow, and the yellow on 

 abdominal segments 3-5 is very narrow, slightly broader laterally ; ventral seg- 

 ments 3-5 with a small, yellow spot on each side. Length, 10-11 mm. 



Montana; Smithville, Southern Dakota (/. T. Altlriih)\ 

 Southern Illinois [Robertson). Related to c/yprata and coinpacta 

 from both of which it will be distinguished by the form of the 

 clypeal lobe in the female. The male will be distinguished from 

 that of clxpcata by the scutellum having two yellow spots antl the 

 shorter and stouter antennre. 



Mr. Wm. Schaus intends to illustrate those species of Amer- 

 ican Lepidoptera which have not been figured |)revi()usly, and 

 he is desireous of obtaining material not represented in his 

 collection. The first part of his work, with three colored plates, 

 has already appeared and treats on South American Zygoenidx' 

 and I'ombvcida;.
