$ . Median lobes orange-brown, the others colourless. Median 

 lobes large, prominent, well-developed, rounded at ends. The other 

 lobes all very small and rudimentary ; 2nd, 3rd, 4th and 5th pairs can be 

 distinguished, becoming successively smaller ; 2nd and 3rd very dis- 

 tinctly bifid. Small saccular incisions between the lobes. Five groups of 

 ventral glands; all the groups rounded or oval, compact; median of 8, 

 cephalolaterals, 13, caudolaterals, 8. Anal orifice circular, a little posterior 

 to line of caudolateral groups, and a considerable distance from hind end. 



A. ancylus differs by its dark scale, and the position of the anal 

 orifice, &c. It is also clearly distinct from Howardi, ostreoeformis and 

 jiiglatis-regice. 



A. Howardi is still only known from Canon City ; the Illinois speci- 

 mens on cherry (VV. G. Johnson), reported as such, prove on examination 

 to be a slight variety of A. ancylus. 



(21) Aspidiotus ficus, Ashm. On Cocos nucifera and Oi'eodoxa 

 regia, lacmel, Hayti, sent by Mr. F. Wolff. New to Hayti. 



(22) Aspidiotus destructor, Sign. On cocoanut, San Juan, Porto 

 Rico. Sent by Mr. J. D. Hall. New to Porto Rico, and the first Coccid- 

 record for that island ! It shows the grouped glands well : caudolaterals, 

 6 ; cephalolaterals, 10 ; median, i only. 



THE BOREAL AMERICAN SPECIES OF PAMPHILA. 



BY DR. HENRY SKINNER, PHILADELPHIA, PA. 



There seems to be some misapprehension in regard to the validity 

 of our species of Famphiia, and inasmuch as I have been studying our 

 Hesperidse for some years past, I thought some remarks on the subject 

 would not be inappropriate. We now have in this genus ninety-six species 

 as they would appear in a list according to the generally accepted specific 

 values. With the exception of about two groups, I consider the species 

 remarkably well defined and constant, and if you once become, 

 thoroughly familiar with them, there is not the slightest difticulty in 

 separating any of them at sight. The great difirculty has been to deter- 

 mine them from descriptions, as the word pictures are often inadequate, 

 and almost impossible to comprehend, as the descriptions seem to fit a 

 number of species that may not be even very closely related. Many 

 of the figures have also been failures to a great extent ; this is particu- 

 larly true of the difficult Comma group, which is in most collections in a 

 condition akin to certain of our species of Argynnis, Melitaea and Colias.
