92 THE CANADIAN ENTOMOLOGIST. 



dimerous, broad and short, its apical half with three whorls of erect 

 bristles. Skin with sparse small round gland-spots. 



Hab. — Andover, Mass., Oct. 27th, 1896, under a stone in the nest of 

 Lasius americaniis, Emery. A small colony of five individuals captured, 

 and only one herd as yet found ; they were not feeding on any roots 

 entering the nest of the ants, but were altogether on the surface of the 

 nest, and some of the ants were attending them. It is to be presumed 

 that they would eventually produce cottony matter. 



Both by colour and habits this differs at once from P. aceris, Sign., 

 which has been recorded from Massachusetts, and there is no species with 

 which it is likely to be confounded. 



Ripersia Blanchardii, n. sp. 



$ . — Dark reddish-purple, segments prominent, much broader in 

 front, pointed behind, subglobular or subelliptical, convex, antennae short 

 and thick. Length, 2 mm.; breadth, i j-4 mm. 



^ (cleared and mounted). — Skin quite thickly beset with round 

 gland-spots, and also minutely hairy, the minute but abundant pubescence 

 being a striking characteristic of the species. So abundant are the hairs 

 in the vicinity of the anal ring that it is impossible to be sure how many 

 really belong to the latter, though there seem to be six, the usual number. 

 The legs, antennae and mouth-parts are tinged with ochreous, and are large 

 for the size of the insect ; particularly the mouth-parts, which have at 

 least twice the diameter, and many times the bulk, of those of the larger 

 species Phenacoccus americance. The mouth-parts are also much broader 

 in proportion to their length than in P. america?ice, and the rostral fila- 

 ments are quite stout. The antennae are stout, 6-jointed, just about as 

 long as in P. auiericance, but very much stouter and quite different in 

 appearance. The formula is (36) 21 (45), but if anything, 3 is a little 

 longer than 6 ; 3 about twice as long as broad; 4 and 5 broader at apex than 

 at base, so that the sutures between 3 and 4, 4 and 5, and 5 and 6, are 

 very deep, the last two approaching a right angle. The whorls of hairs 

 are very sparse. The legs are also peculiar ; fully a third longer than in 

 P. americance, and very stout, with large coxaj and trochanters, they are 

 tolerably thickly beset with small hairs. The tarsus is somewhat over 

 two-thirds the length of the tibia, and tapers quite rapidly from a broad 

 oblique base, it shows a slight tendency to be jointed a little before the
