distally than in rileyi ; second and tliird joints 

 equilateral like the following ones, not 

 oblique with one side produced as in rileyi; 

 second joint sensibly shorter than the third; 

 third slightly longer than the fourth; fourth 

 to ninth about equal in length, hut the distal 

 joints narrower than the proximal; terminal 

 joint similar to the penultimate one, whereas 

 in rileyi the last two joints are dissimilar. 

 Prothorax as in rileyi, shining, sparsely 

 punctured ; elytra about as in rileyi; covering 

 at the sides about two-thirds of the first 

 abdominal segment. Hind margins ofabdom- 

 inal segments narrowly testaceous; surface 

 of segments shining, with broad shallow 

 punctures. At the sides the ventral segments 

 encroach upon the dorsal area, the dorso- 

 ventral sutures being marked by deep sub- 

 lateral channels. Legs as in rileyi; claws 

 simple, with a strong basal bristle. 



Hab. — Mesilla, New Mexico, about the 

 first of August, 1896, on a wall in which were 

 many nests o{ Anthopliora vallorum (Ckll.). 

 This was sent at the time of its discovery to 

 Dr. Horn, and it is much to be regretted 

 that he did not live to publish an account of 

 it. When recently in Philadelphia, I found 

 it in Dr. Horn's collection, and was able to 

 draw up the above description L. neotnex- 

 icana is very distinct from Hornia minntipcn- 

 >tis, and quite sufficiently so from Leonia 

 rileyiy as the following table of the North 

 American Sitarini shows : — 



Antennae 11 -jointed; head, thorax and 



legs bright ferruginous. 



Horiiiu minutipennis Riley 



Antennae 10 -jointed. 



Black; elytra fulvous ; second and third 

 antennal joints equilateral. 



Leonia 7teomexicana Ckll. 

 Dark ferruginous ; elytra testaceous ; 

 second and third antennal joints conspic- 

 uously inequilateral 



Leonia rileyi E. Duges. (Mexico.) 



All three are parasitic in nests of Antho- 

 pliora. T- p. A- Cockerell.

A NEW PULVINARIA FROM MASSA- 

 CHUSETTS. 



Pnlvinuria cockeyelli. n. sp. ? Scale 

 yellowish brown, small, nearly hemispherical 

 in outline, slightly convex, 4 mm. long, 34 

 mm. broad. Ovisac 7 mm. long, 3 mm. broad 

 and a little more than i mm. in thickness. 

 Texture soft, clear white, powdery and 

 sticky. Eggs small oval, white, situated in 

 an oval cluster on the under side of the leaf 

 beneath tlie ovisac. Newly hatched larvae 

 clear white. ? Scale cleared and mounted 

 transparent slightly tinged with yellow. 

 Legs, antennae, mouthparts and anal plates 

 light yellow. Antennae 8 segmented, 3 quite 

 long, 4 next, 7 is the shortest (see table of 

 measurements all in micromillimeters). The 

 hairs on the antennae are as represented in 

 the drawing, usually 18. The length and 

 breadth of tlie antennae seem to be quite con- 

 stant in all of the material examined. Legs 

 normal. Coxa broader than long, the legs 

 usuall3' have about 22 hairs on each (see fig- 

 ure of leg). Marginal spines stout, bulbous 



at base, tips sharp, 6 micromillimeters lonj 

 they are very easily lost in mounting.
