326 THE CANADIAN ENTOMOLOGIST. 



new species the s. t. line is a much more distinctive feature, particularly 

 in the tooth which it sends to the t. p. line in the submedian interspace. 

 There is another undescribed species from California belonging to 

 this genus ; but the material is at present insufficient to enable me to 

 characterize it properly. I call attention to this fact at present because 

 the female type of obliquata is from California and is not the same 

 species as the male examples which I marked type from Colorado. In 

 other words, what I considered at the time that I described obliquata to 

 be sexual differences are really specific. I have since seen male examples 

 from California that agree with my female type, but have no male myself 

 to authorize a description. 



THE COCCI D GENUS SPH^ROCOCCUS IN MASSACHUSETTS. 



BY T. D. A. COCKERELL AND GEO. B. KING. 



Sphcerococcus syhestris, n. sp. 



Much like an Eriococcus in shape, 23^ millirn. long, i^ wide, dark 

 dirty brown, with a little white cottony down at its anal end, and on the 

 mid-dorsal line a distinct longitudinal nearly white band. (King.) 



9 • — Boiled and mounted in balsam, broad oval, 2 millim. long, 

 transparent, without legs. Antennae pale brownish, thick, subconical but 

 very blunt at end, about 100 \t. long, five-segmented ; of the segments, 3 

 is longest, and about as broad as long ; 5 next longest, slightly longer 

 than broad ; the others more than twice as broad as long, very short, 4 

 the shortest ; 5 with a few bristles at tip. Mouth-parts yellowish-brown, 

 very large and well-developed, about 200 //. wide. Anal ring hairless ; 

 caudal tubercles quite absent, their place represented by a {q'n hairs. A 

 few circular dermal glands in the caudal region. Two large stout spines, 

 and a few small ones, on each side of the 'body. Spiracles as usual in 

 the genus. (Ckll., from King's Mount.) 



Hah. — Methuen, Mass., June 15, 1898, on white oak. (King.) 



This is a most interesting discovery in every way, no SpJue.rococcus 

 being hitherto reported from America. Whether the present insect is 

 strictly congeneric with Maskell's type of Sphcerococcus from Australia, 

 must remain uncertain until the newly-hatched larva is found ; but there 

 is nothing in the adult $ on which to make a generic sejjaration. At all 

 events, our insect is surely congeneric with Sphcerococcus parvus, Maskell, 

 found on cherry, and possibly on oak, in Japan. 



S. syhestris will be readily known from parvus by its better 

 developed antennae.
