PSYCHE.

cavities and spots on propleurae black. 

 Medium spots on vertex much larger. Basal 

 angles of scutel and two dots in front of the 

 transverse line, black. Elytra without fus- 

 cous areas. 



Male: Plates long, about two and a lialf 

 times as long as total breadth at base, sides 

 concave on basal two thirds, thence from the 

 obtuse angle thus formed strongly narrowed 

 to the tips. Differs in color from the female 

 as follows : Head and scutel other than 



markings bright yellow. Spots at ocelli 

 larger and including ocelli. Vertex with a 

 large median black spot at base. Pronotum 

 with two points at apex and a median line, 

 blackish. Veins of elytra somewhat darker 

 towards base. 



State of Vera Cruz, Mexico (Rev. 

 H. Th. Heyde). This species belongs 

 to the novella group Ijut is very distinct 

 from either novella oi' anoviala. 



THREE NEW COCCIDAE OF THE SUBFAMILY DIASPINAE. 



BY T. D. A. COCKERELL, MESILI.A, NEW MEXICO. 



Aspidiotus {Diaspidiotiis) coniferariim, n. 

 sp. — 5 scale I 1-3 mm. diam., circular or 

 nearly so, rather convex (about as in raptix), 

 white, with the red-brown exuviae to one 

 side of the middle. First skin usually ex- 

 posed. A white ventral film. 



5 yellowish-brown, of ordinary form; no 

 circumgenital grouped glands; median lobes 

 close together, large, broad and low, rather 

 like those of sfiircatus ; second lobe low and 

 broad, subobsolete but marked by the wide 

 depression between it and the first lobe, it 

 resembles the same lobe in belulae, but is 

 longer; third lobe a rounded prominence, 

 hardly a lobe, as in beiulae; three spine-like 

 plates (gland-hairs) in the first interlobular 

 interval; three, larger, behind the second 

 lobe; these branch more or less, the last 

 especially having two long lateral branches; 

 a long and strong spine just beyond the third 

 lobe, and another similar spine on the mar- 

 gin a good distance beyond. The two pairs 

 of interlobular incisions are very well-formed 

 and are like those of betulae. Anal orifice 

 large, and only a short distance from the 

 hind end. Lateral portions of caudal plate 

 with numerous filiform (spermatozoon-like) 

 glands. 



The embryonic larvae, in tlie body of the 

 ? . are remarkably large, and have the legs 

 and antennae well formed. 



//((/<. — Organ Mts., New Mexico. De- 

 tected by Mr. II. Casad on a small pine tree 

 (doubtless Piiiiis fonderosa v. scopulorum) 

 which was brought to Mesilla and used as a 

 Christmas tree. The scales occur plentifully 

 on the upper part of the trunk. A. conifer- 

 arum is more like certain European species- 

 than any found in America; it probably 

 occurs far to the north, and belongs to the 

 boreal or subboreal fauna, reaching its most 

 southern limit, like some other species, in 

 New Mexico. It is infested by a fungus. 



Pseitdoparlatoria noarki^ n. sp. — ^ scale 

 I 2-3 mm. diam., flat, or very slightly convex, 

 circular or nearly so ; stained with light cof- 

 fee-brown, except the margins, which remain 

 white, sometimes the whole scale being wliit- 

 ish ; exuviae central to sublateral, rather 

 large, exposed, first skin near margin of 

 second, both skins orange-brown, varying 

 to very pale greenish yellow, the first skin 

 sometimes greenish with a yellow spot at 

 each end. A white ventral film. $ scale 

 smaller, broad-oval, flat, semitransparent 

 white ; larval skin large, slightly greenish,
