Coquillett, of Los Angeles, iu which that gentleman tells me 

 that in California there are two As]>idioti on citrus : the one 

 is A. aurantii, the other is different in a few respects. After 

 seeing the Samoan insect I incline to the belief that A. cydonice. 

 may be this other species, and in consequence that the orange 

 may be as much its food-plaiit as the quince, if not indeed the 

 principal one. 



Genus Chionaspis, Signoret, 



Chionaspis eugenise, sp. nov. Plate I., figs. 10-12. 



Female puparium white, or sometimes yellow, elongated, 

 pyriform, flattish ; length about xV^^- Pellicles terminal, 

 yellow, not large. 



Male puparium white, elongated, soft and cottoiiy ; often 

 appearing like a small irregular mass of cotton, but iu indi- 

 viduals of normal form a distinct carination is visible. 



Adult female elongated, yellow or brown : abdomen ending 

 with a shallow median depression, the two median terminal 

 lobes being represented by thickenings of the margin at the 

 depression with serrulated edges : four very small lobes can be 

 in most cases detected at each side, but this depends on the 

 position of the specimen : a short spiny hair at each side of 

 the depression ; one, longer, between the four small lobes, and 

 two others at equal distances on each margin : four altogether 

 on each side : and on each of the anterior abdominal segments 

 of the body three or four spines. Spinneret-groups five ; upper 

 group, 6-8 orifices; upper laterals, lC-18 ; lower laterals, 

 18-20. Several large single spinnerets. 



Adult male unknowai. 



Hah. In Australia, on Eugenia elliptica, Viburnum sp., 

 Leptospcrmum IcRvigatum, Melaleuca er id folia, &c. Specimens 

 sent by Mr. French. The female puparia seem identical 

 on all these plants, excepting a slight variation in colour : the 

 male puparia on Melaleuca are frequently very loose and 

 fluffy, and Mr. French tells me that the plants look "as if 

 covered with snow\" 



In the abdominal margin this species approaches to 

 C. nysscs, Comstock ; but differs in other characters. 



Chionaspis these, Maskell. 



On tea-plants in the Kangi-a Valley, Assam, occurs an 

 insect of which specimens have been sent to me by Mr. Cotes, 

 of the Indian Museum : their description is to appear in the 

 " Indian Museum Notes." The female puparium is pyi'iform, 

 flat, light-brown : the female insect shows no very striking 

 characters, but the abdominal segments are somewhat con- 

 spicuous. The male puparium is very small, white, and so 

 markedly carinated that it has quite Q> fluffy appearance, as if
