64 THE CANADIAN ENTOMOLOGIST. 



on each side of strong, similarly-coloured, but shorter, spines, ten to 

 twelve in number • nearer the medio-dorsal line there are four pairs 

 of spines on the thorax, and a pair on abdominal segments i, 2, 3 and 7, 

 respectively. Vasiform orifice prominently elevated on an oblique, 

 subconical, truncated protuberance, the subcordate orifice opening 

 directly upwards. The operculum is similar in shape to orifice, which it 

 nearly fills. Lingula obscure. There is a narrow, more or less evident 

 marginal rim, composed of the prominent wax tubes, which are bluntly 

 rounded distally, the incisions between them being moderately deep and 

 acute On ventral surface rudimentary legs may be readily distinguished. 



Adults unknown. 



Specimens collected by Mr. C. L. Marlatt, Garolt, Java, December 

 7, 1 901, on Citrus, sp., and Rose. Eggs and pupal stages described from 

 numerous specimens ; larvce from two specimens. This species is closely 

 related to Maskell's piperis from Ceylon, but differs in the number 

 and arrangement of spines in the vasiform orifice, and in the fact 

 that the eggs of spinifera are distinctly marked with polygonal areas, 

 whereas those oi piperis are striated. Types in U. S. National Museum. 



TWO REMARKABLE NEW COCCI D^. 



BY T. D. A. COCKERELL, EAST LAS VEGAS, N. M. 



Of the two Coccidfe now described, the first is the type of a very 

 peculiar new genus ; the other is a very beautiful and interesting 

 lac-insect. 



Stictococcus, n. g. — An aberrant genus of Lecaniin*, with the anal 

 orifice in the middle of the back, not connected with the hind margin by 

 a slit or groove. Anal ring with six hairs in larva ; none in adult. Anal 

 plates so modified in adult as to be unrecognizable. Legs small, but well 

 developed. Antenna with 5 or 6 joints. Margin with long bristles, and 

 flattened bifid or palmate plates or spines. Dorsum with numerous large 

 pits. 

 Stictococcus SJostedti, n. sp. (V. D. A. .\: W. P. Ckll.). 



Numerous on small branches. Oval, flattish, about 4 mm. long, 3 

 broad, and i }4 high; Lecanium-Wke, smooth and shiny, ferruginous to 

 olive-brown ; anal orifice in middle of back ; dorsal region with two 

 longitudinal rows of large round pits, single and (in two cases) two 

 together : thus, i, r, 2, i, 2, i, 1, and then a single one in the middle line 

 where the two rows converge. Subdorsal region with a row on each sidp
