new Coccidse from Mexico. 429 



cJ . — Scale white, Diaspis-WVo,^ with pale yellow larval skin 

 at one end. The scales are very minute, and the projecting- 

 white portion is not as long as the larval skin. 



Hob. Amecameca, Mexico, June 6, 1897, on bark of oak 

 (Koehele, 1753). Div. Ent. 7965. 



A most interesting insect, connecting the Dlaspinge with 

 the Coccin£e. 



Sohnophora Koeheleij sp. n. 



Near to 8. corokioe^ Mask., but much larger. The oldest 

 females are in a rounded dull black scale, 5 millim. long, 

 A\ broad, and 3 high, the hind part hardly produced. On 

 breaking this open one finds the shrivelled body of the 

 female lying loose within, with a mass of yellowish-white 

 empty egg-pellicles. The dried female has a dark purplish 

 tint. In the penultimate stage the test or scale is from 3 to 

 A\ millim. long, broadly oval in outline, flat or even depressed 

 in the middle when dry, with a blunt dorsal keel or row of 

 protuberances, on each side of which is a subdorsal row of 

 protuberances, often inconspicuous. Margin convex, raised, 

 more or less nodular, with three white transverse lines of 

 secretion about the middle. Caudal end with the usual 

 orifice, but hardly at all produced. 



$ . — Anal lobes and ring (with six hairs) as in Maskell's 

 figure of corokice ; skin crowded with short rod-like pi'O- 

 cesses ; mouth-parts small but well- formed ; no legs or 

 antennae ; on the abdomen on each side of the middle line are 

 two large oblong brown patches, close together, the anterior 

 of each pair the larger, their surface granular or minutely 

 reticulated. 



(J. — Scales small and elongate, reminding one of those of 

 Tachardia ; dark in colour, with a red tint, or sometimes 

 more or less yellow. Their inner surface is pale yellow. 



Hab. Tulare, Mexico, Aug. 8, 1897, on Cratcegus and 

 Prunus demissa {Koehele^ 1659). Div. Ent. 7891. Also 

 on Cratcegus from Mexico (locality and date not stated : 

 Koehele, 1632). 



The discovery of Solenophora in Mexico is most remark- 

 able, as the genus has hitherto been known by only two 

 species (both of which are before me) from New Zealand. 



leery a {Proiicerya) littoralisj sp. n. 



$ . — About 3 millim. long, with sac 10 millim. ; breadth 

 of sac nearly 4 millim. Dorsum entirely covered by snow- 

 white secretion ; some irregular lateral cottony tassels. Ovi-
