ondaries have the abdominal margin comparatively more deeply edged with 

 black, the line being distinctly bent inwardly toward the extremity of the cell; 

 the colored spots are very small, almost obsolete, becoming simply pale pink- 

 ish or yellowish dots, surrounded by a narrow black ring. Under side vit- 

 reous, with a yellower tinge than above; all the marks fainter, except the col- 

 ored spots of the secondaries, which are here, though small, distinct in color, 

 and have white pupils. There is also a faint indication of a black bar on the 

 anal angle, but no trace whatever of crimson basal patches. Head, thorax 

 and abdomen beneath densely clothed with deep yellow hair, much darker and 

 a more brilliant tint than in the typical form. 



Exp. of wings, 2.25 inch. 



$ . In nearly all respects this sex of the present variety resembles the J* 

 of the type, and would at first sight be certainly so regarded. The transpar- 

 ent space of primaries is much smaller than usual; the bands are narrower 

 and less defined, so that the white area of the wing is nearly as large as that 

 of the male insects. The black patch in the submedian interspace is rather 

 large, and the veins more sharply marked throughout. The secondaries have 

 the colored spots small, but distinct in color, mostly pale crimson or orange, 

 and surrounded by a black ring. The abdominal margin is only faintly black, 

 and there is a trace of a black bar at the anal angle, which is, however, en- 

 tirely without red. Under side similar to the upper in the black markings; 

 the colored spots of secondaries are bright in color, and in some specimens 

 there are two basal red patches, the anal bar more distinct than above, but 

 without red. There is a seam of yellow hair along the abdominal margin, sur- 

 mounted by yellow scales, a character which I do not find in my typical spec- 

 imens of Clodius, and the yellow hair of the thorax and abdomen are almost 

 golden in their tint. 



Exp. of wings, 2.50 inch.

Pa7-nassius Smintheus. Dby. Var. Behrii. Edw. 



I have two specimens of this insect in my collection, one taken by Mr. J. 

 Hutchings, of Yosemite, on the top of Mt. Dana, Cal., at an elevation of 

 10,000 feet, and the other by Mr. I. D. Putnam, in Summit Canon, Utah. It is 

 somewhat singular that the typical form of Smintheus never occurs in Califor- 

 nia, while the variety should be found here. Both of my specimens have the 

 spots orange, and the double row of marginal lunules on the secondaries so 

 characteristic of this strongly marked form. 



Pieris venosa. Scud. 



Perhaps there is no group so puzzling to an entomologist as that of the genus 

 Pieris, to which this species and its allies belong, and the number of names 

 which we find in our catalogues are the natural outgrowth of the widely different 

 variations which we find in collections. Our Pacific Coast species rather tend 

 to increase the confusion than otherwise, and in the separate opinions which 

 exist as to their specific rank the complication becomes more and more intri-
