248 HEMIPTERA-HETEROPTERA. 
with a row of tomentose white spots. The males have the apex of the last genital 
segment produced in the middle and armed with a sulcate, pointed spine of variable 
length ; the outer genital lobes are narrow and the short inner lobes blunt at the tip. 
Our specimens vary from 103-15 millim..in length. 
6. Milyas infuscatus, n. sp. 
Elongate, rufo-testaceous or reddish-ochreous, pilose; the head with a spot between the ocelli, two oblique 
marks between the eyes, and a spot in front, reddish; the pronotum piceous or black, with the anterior 
angles, some marks on the anterior lobe, and the basal margin, except for a short space towards the sides 
and in one specimen a spot on each side near the lateral angles and another on the disc behind, reddish ; 
the base of the scutellum and the elytra piceous or black, the membrane smoky; the abdomen above and 
beneath broadly banded with black, the black in some specimens so extended on the venter as to enclose 
four rows of large transverse spots of the ground-colour, the pleura also spotted with black; the antennze 
with joints 1 and 2 black, 1 triannulated with rufo-testaceous, 2 with a reddish median ring, 3 and 4 
obscure ferruginous ; the legs and the basal joint of the rostrum broadly annulated with black; the pleura 
and the sides of the venter each with a row of tomentose white spots. Head moderately long ; antenne with 
joint 1 about twice as long as 2, 2 and 4 subequal, 38 much longer than 2, Pronotum smooth, deeply 
sulcate down the centre from the middle of the posterior lobe to the apex, the anterior and lateral angle 
each armed with a short tooth ; the reflexed basal margin sinuate on each side. Scutellum with the apex 
strongly foliaceous. Legs moderately elongate. 
3g. Terminal genital segment produced in the middle at the apex and armed with a rather long stout spine, 
which is deeply sulcate down the middle and blunt at the tip; the genital lobes moderately stout, the 
short inner lobes somewhat angular at the tip. 
Length 13-14, breadth of the pronotum 33-3? millim. (d 2.) 
Hab. Guaremaa, Zapote, Capetillo, Duefias (Champion), Guatemala city (Salvin). 
Nine specimens, most of which are in a bad state of preservation. /. infuscatus is 
probably an extreme form of the very variable MM. zebra, but as it appears to be 
localized in Guatemala I have ventured to name it. In some examples the black 
markings on the venter are so extended as to enclose four series of large transverse 
pale spots. 
7. Milyas rufofasciatus, n. sp. (Tab. XV. figg. 8,3; 84a, last genital seg- 
ment, ¢ .) 
Elongate, pilose, pale stramineous ; the head maculated with black above, the post-ocular portion black, the 
sides in front and a spot between the ocelli excepted ; the anterior lobe of the pronotum faintly variegated 
with black, the posterior lobe with a broad rufous band—extending from the apex to near the base, to 
the lateral spines, and also on to the pleura; the elytra testaceous, with the membrane subhyaline ; the 
abdomen above and beneath narrowly banded with black; the antennz with joints 1 and 2 black, 
1 quadriannulated with stramineous, 2 with a stramineous median ring, 3 and 4 ferruginous; the basal 
joint of the rostrum and the legs narrowly annulated with black; the pleura and the sides of the ventral 
segments each with a row of small tomentose white spots, the head with an oblique fascia of white hairs on 
each side behind the ocelli. Head moderately long; antenne with joint 1 about twice as long as 2, 
2 and 4 equal, 3 much longer than 2. Pronotum smooth, sulcate down the middle from the centre 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 with the reflexed margin slightly sinuate and forming a rather 
prominent lobe on each side of the median emargination. Scutellum with the apex rounded and strongly 
foliaceous. Legs moderately elongate.
