250 HEMIPTERA-HETEROPTERA. 
than 2. Pronotum smooth, suleate down the centre from the middle of the posterior lobe to the apex; 
the anterior angles armed with a short, stout tooth, the lateral angles with a short outwardly directed 
spine; the base subtruncate in the centre, the reflexed margin sinuate and forming a short lobe on each 
side of the emargination. Scutellum with the apex rounded and strongly foliaceous. Legs moderately 
long. 
3. Terminal genital segment armed with a short slender sulcate spine; the genital lobes very slender. 
Length 104-11; breadth of the pronotum 3, of the abdomen 23-32 millim. (¢ 9.) 
Hab. Mexico, Ventanas in Durango (Forrer). 
One male and two females, agreeing precisely in colour. This species is chiefly 
distinguishable by the pallid coloration, the clearly biannulate second antennal joint, the 
peculiar markings of the head (which are constant), the narrowly annulate legs, and 
the very slender short spine at the apex of the last genital segment in the male. It is 
perhaps yet another form of WM. zebra. 
10. Milyas nigropictus, n. sp. (Tab. XV. figg. 11,4; lla, last genital seg- 
ment, ¢ .) 
Elongate, rather narrow, sparsely pilose, pale stramineous; the head black above, with a small spot between 
the ocelli and some marks between and before the eyes pale stramineous ; the pronotum with the anterior 
lobe variegated with black (a spot at the sides, some oblique marks on the disc, and the anterior angles 
remaining pale), the lateral spines and sometimes a. spot or streak behind them, and, rarely, an interrupted 
transverse fascia before the base, black; the scutellum fuscous at the sides below the base; the elytra 
dilute fuscous ; the connexivum banded with black; the sides of the venter more or less, and the sutures 
laterally, as well as the pleura in part, marked with black; the antenne with joints 1 and 2 black, 
1 quadriannuJated with stramineous, 2 with a median ring and the apex very narrowly stramineous, 
3 and 4 ferruginous ; the basal joint of the rostrum, the femora, and the basal halves of the tibia narrowly 
annulated with black; the pleura and the sides of the venter each with a row of tomentose white spots, the 
basal portion of the head, the posterior lobe of the pronotum in front, and the scutellum with similar spots 
or streaks. Head moderately long; antenne with joint 1 about twice as long as 2, 2 and 4 subequal, 
3 much longer than 2, Pronotum smooth, sulcate down the centre from the middle of the posterior lobe 
to the apex; the anterior angles with a long tooth; the lateral angles with a long, slender, outwardly 
directed spine; the base subtruncate at the middle and sinuate at the sides, the margin rather broad and 
reflexed. Scutellum with the apex narrowly foliaceous. Legs moderately elongate. 
3. Terminal genital segment armed with a short tooth ; the genital lobes slender, with a long curved bristly 
hair at the tip. 
Length 93-104, breadth 24-3 millim. (¢ @.) 
Hab. Mexico, Dos Arroyos in Guerrero, Atoyac in Vera Cruz, Teapa in Tabasco 
(H. H. Smith), San Lorenzo, near Cordova (M. Trujillo). 
Twelve specimens, one only of which isa male. Distinguishable by the long slender 
spine at the lateral angles of the pronotum, resembling that of 1. punctipes, but less 
elongate; the scutellum is also narrowed at the apex, as in that insect. In fresh 
examples there is a row of conspicuous spots of white tomentum down the pleura and 
sides of the venter, as well as others on the head, pronotum, and scutellum.
