222 THE CANADIAN ENTOMOLOGIST. 



I am convinced that these are the sexes of one species, but the ^ 

 and $ would come at opposite ends of Mr. Dunning's table (Can. Ent., 

 XXVIII. , 206). The males known from North America, with three teeth 

 on the anterior edge of the clypeus, may be separated thus : — 



( [.) Ground colour rufous ufa/ie/isis, Baker. 



(2.) Ground colour black. 



(a.) Head and thorax densely hairy. . .hispidus, Fox (L. Gala.), 

 (b.) Head and thorax not unusually hairy.. . .concinnulus, Ckll. 

 The female of co7icinnulus is smaller than quadi-inotatus, and has not 

 the black head and thorax. 



NEW COCCID.-E FROM MASSACHUSETTS AND NEW MEXICO. 



BY T. D. A. COCKERELL, MESILLA, N. M. 



In Europe and in New Zealand species of the genus Ripersia have 

 been found, which lived in the nests of certain ants. It had alwavs 

 seemed to me singular that nothing of the kind should occur in this 

 country ; bui: Mr. G. B. King has proved that they merely wanted look- 

 ing for, his researches in Massachusetts having led to the discovery of 

 three species, here briefly described. 



(i.) Ripersia Kingii, n. sp. — $. About i^^ mm. long, oval, legs 

 and antennaj very pale yellowish ; the natural colour of the insect could 

 not be determined from the alcoholic specimens, but Mr. King states 

 that when alive it is pink, shading into purple. Mentum (so-called) 

 elongate, dimerous, with four bristles in a group at each side near the 

 tip, and two on the sides further up, at considerable intervals. Antennae 

 fairly stout, 6-jointed : 6 much longest, and about as long as 3, 4 and 5 

 together. Formula 6 (21) (534). All with very sparse whorls of hairs, 

 6 with 3 whorls. Femur stout, with four bristles on its outer margin. 

 Tibia a little shorter than femur, with four long bristles on outer margin 

 and two on inner. Tarsus distinctly longer than tibia. Claw very long, 

 sharp, not much curved. Digitules very inconspicuous, filiform, with 

 very minute knobs. Anal ring with 6 moderately small hairs. Caudal 

 tubercles low, scarcely developed, with several hairs like those of the 

 anal ring. Dermis with very few short hairs. Antennae about as far 

 apart as the length of a femur. 



Hab. — Dracot, Mass., April 14, i8g6, with Lasius flavus, L., very 

 abundant [G. B. KingJ. From the character of the legs, I think these 

 specimens are only of the second stage, but in any event the species
