and has the remarkable feature of lacking the sexual band of androconia 

 or special scales, which is such a striking characteristic of the males of 

 all the other species in the genus. The plate is a very beautiful one, and 

 shows a pale male and the full lifehistory with the exception of the 

 pupa. The female figured, although of course copied from an actual 

 specimen, is hardly typical of that sex, and it is to be hoped that at some 

 future time Mr. Edwards will publish another illustration showing the 

 more usual form, which has a much richer appearance both oa the upper 

 and under sides. 



Ch. Macounii is decidedly a variable species, both in the intensity of 

 the golden brown of the wings, in the amount of infuscation along the 

 nervures, and in the size and number of the ocelli. Both sexes frequently 

 have three ocelli on the primaries, and occasionally four. One specimen 

 in my collection, plainly a male, has four distinct ocelli on the primaries, 

 the second and fourth from the apex large and pupilled. In fact, this 

 specimen has more nearly the markings of what appears to me the typical 

 form of the females. There is also a very much infuscated variation (;f 

 the male which is rarely taken, in which the nervures are all broadly 

 bordered and the greater part of the surface of the disk is covered with 

 dark scales. One of these was mentioned by Mr, Edwards in his 

 original description (Can. Ent., XVII., p. 74), and was omitted from the 

 plate now published for want of space. The life-history of this species 

 has not yet been fully worked out, as no one has succeeded in obtaining 

 the pupa. It will probably be much like that of Ch. Chryxus ; but for 

 the present it is unknown, and it remains for some expert and patient 

 breeder to carry the larvae through all their stages and obtain this missing 

 link. The eggs are easily obtained when a female has been captured ; 

 but the breeding is very tedious, the larval life lasting nearly two years.

Every student of the Hymenoptera must be delighted at the issue of 

 this magnificent volume, which bears most ample testimony to the exten- 

 sive studies and patient industry of the author. Treating, as he does, of 

 a family in which the American species had previously been but meagrely 

 represented in collections, he has necessarily been compelled to describe
