330 On new North- American Insects. 



from A. neomeccicana in the dark (instead of pallid) second 

 nervure and the impressed lines of the thorax being feebly or 

 not pubescent. The life-history is quite different. 



VIII. — Two new Species of Kermes (Fam. Coccidas) from 

 the Eastern States. 



Kermes nivalis, King and Ckll., sp. n. 



$ . — Rather Lecanium-like, with a broad base of attach- 

 ment, outline much like that of a convex Lecanium, the sides 

 depressed, not bulging. Length 4£, breadth 4£, height 

 about 3 millim. Dark sepia-brown, irregularly marbled with 

 blackish and pale ochreous, the latter colour inclined to be 

 arranged in transverse bands, and beset with numerous minute 

 dark dots. All of the scale except the middle of the back is 

 powdered with snow-white secretion, which becomes very 

 abundant at the sides. Microscopical characters ordinary ; 

 skin fairly closely beset with small round glands, and showing 

 some larger glands at irregular intervals, on brown patches. 

 Mouth-parts ordinary. Antennas distinct, but rudimentary, 

 obscurely 6-jointed, last joint bristly. 



Larva (newly hatched). — Pale yellow, rather more elon- 

 gate than usual, lateral spines very small and short. An- 

 tennas 6-jointed, 3 at least as long as 4 + 5. Formula 

 3 6(1245). 



Hab. Lawrence, Mass., on Quercus alba (G. B. King, 

 no. 48). The larvas hatch about the beginning of August. 



This pretty species differs from all those described from 

 North America by its shape, and especially the snow-like 

 meal on its sides. It agrees in some respects with the 

 European K. Bauhinii. I have not seen this latter species, 

 but there are specimens in the U.S. Nat. Museum, and 

 Dr. L. O. Howard has kindly compared them with K. nivalis, 

 and finds them "very different." 



Kermes Kingii, sp. n. 



? . — Very convex, but the sides hardly bulging ; length 5, 

 breadth 4£, height about 3| millim. Colour light ochreous, 

 of quite a bright tint, marbled with a slightly darker redder 

 tint; the marbling is absent in the mid-dorsal line, leaving a 

 more or less distinct longitudinal pallid band ; segmentation 

 vaguely indicated by transverse rows of small black spots ; 

 entire surface very closely beset with minute dark dots. The 

 scale is evenly rounded dorsally, without any prominences or 

 depressions. Microscopical characters as usual in the genus,
