smooth, shining, minutely very sparsely punctulate ; clypeal emargina- 

 tion broad and shallow, sides rounded ; genae slightly prominent, obtuse. 

 Prothorax not narrowed in front, sides strongly, evenly arcuate, fimbriate 

 anteriorly ; basal angles not defined, basal marginal line strong through- 

 out, the median lobe moderately prominent ; surface minutely alutace- 

 ous but strongly shining, punctuation rather sparse, intermixed. Elytra 

 slightly wider than the prothorax, humeri not dentate, striae rather deep, 

 very faintly or scarcely visibly punctulate ; intervals convex, each with a 

 nearly regular series of very fine, feeble, distinct punctures. Beneath 

 finely alutaceous and strongly shining, mesosternum not carinate, metas- 

 ternum very sparsely punctate, ventral segments with a row of rather 

 coarse setigerous punctures along the anterior margin of each, other- 

 wise impunctate. Anterior tibiae smooth in front, externally tridentate, 

 the terminal tooth normal, the upper tooth small, margin above not 

 crenulate ; tibial spurs slender and nearly straight, not differing in the 

 sexes. Length 3-3 >^ mm.

A rather pretty little species, allied to phalerioides and larrea, 

 but smaller than either and differing from both in the elytral 

 markings, the minute or obsolete punctures of the elytral 

 striae, the partial fimbriation of the side margins of the 

 prothorax, and the ventral punctuation. In both phalerioides 

 and larrecB the side margins of the prothorax are fimbriate 

 throughout and the ventral segments are irregularly punctate. 

 In larre^ the base of the prothorax is broadly evenly arcuate 

 with scarcely a trace of median lobe ; there are also sexual 

 differences in the clypeus which do not obtain in kriausii. 



Notes on the Life History of Anthocharis genutia Fab.* 

 By John A. Grossbeck. 



Amongst the first of our New Jersey diumals to appear in 

 the spring from hibernating chrysalids is the little orange-tip 

 butterfly, Anthocharis genutia. This species was considered a 

 rarity — at least in northern New Jersey — and it is only in 

 recent years that the collectors in this vicinity have added 

 it to their collections. It is not at all uncommon on Gar- 

 ret Mountain, Paterson, but seems to be confined to a very 

 limited area. This, however, is accounted for by the fact, that
