abdominal bands as in rinconis, with curved anterior margins ; hair at 

 apex of abdomen yellowish fuscous. 



Hab. — San Pedro, California, July 27, 1901, at flowers of Opuntia, 

 gathering pollen. 17 9- First found by my wife. This will probably 

 be regarded as a distinct species, but it is certainly very near to D. 

 rinconis, which visits flowers of Opuntia in New Mexico (Entom., Sept., 

 1900, p. 245). The chief difference between rinconis and opuntice is 

 in the much more strongly and densely punctured thorax of the latter ; 

 opuntice is also on the average a considerably bulkier insect. From the 

 Californian D. friesei, opuntice differs in the larger size, closer punctua- 

 tion of thorax, and the character of the abdominal bands.

Illustrations of Unfigured Lepidoptera. — By A. G. Weeks, Jr., 360 

 Washington St., Boston, Mass. 



We have received from the author the first thirty-one pages of this 

 work, which he is publishing for private distribution at his own expense. 

 This portion contains the description of seven species of butterflies, all 

 but one of which have been already published elsewhere, but a.re now 

 illustrated by most beautifully-executed coloured lithographs from draw- 

 ings by Mr. J. Henry Blake. The species are all from tropical or 

 sub-tropical regions and the types are in the author's collection. The 

 exquisite plates compare very favourably with those in Mr. \V. H. 

 Edwards's "Butterflies of North America," which have set a high standard 

 of artistic merit and truth to nature. 



An interesting account is given of a collecting trip in Bolivia, made 

 by Mr. Gerhard, of Philadelphia, who was sent by the author to that 

 out-of-the-way and little-known region in order to secure as complete a 

 collection as possible of the butterflies of the country. Though the 

 region explored was in the high altitudes of the Andes, where vegetation 

 was mainly confined to the mountain ravines and river gorges, the 

 collector succeeded in obtaining, during an absence of a little over a year, 

 thirteen thousand butterflies, over a thousand dragon-flies, a thousand 

 beetles, twelve hundred moths, and a large number of other insects. 

 Among these there will no doubt be found many species hitherto
