In this genus the posterior margin of the pronotum is truncated and the scutellum 
is distinctly punctate. 
1. Miris affinis. 
Miris affinis, Reuter, Ofv. Vet.-Ak. Férh. 1875, p. 59. n. 1’.

Hab. Nort America, Wisconsin 1, Pennsylvania !, Colorado 2.—Mextico (coll. Dist.). 
I have felt little hesitation in identifying a single Mexican specimen as belonging to 
the above species ; and there seems little doubt that both Dr. Reuter’s and Mr. Uhler’s 
description refer to the same insect. Both their publications bear date 1875, but I 
give the priority to the first as being the earliest received, at least in this country. 
2. Miris guatemalanus, n. sp. 
Allied to M. affinis, but larger ; the colour pale ochraceous; antennz with the basal joint finely but strongly 
pilose, the second joint with its apex more or less distinctly infuscated. Head obscurely pilose, the central 
sulcation distinct and narrow, with a longitudinal fuscous fascia on inner side of eyes, and the extreme 
base also more or less distinctly fuscous. Pronotum coarsely punctate, the lateral margins and a central 
longitudinal line levigate and pale luteous; a fuscous submarginal fascia on each side, broadest and badly 
defined near anterior margin ; the lateral angles subprominent, subnodulose, and pale luteous. Scutellum 
somewhat obscurely punctate and pilose, with a central, longitudinal, levigate pale luteous line, moderately 
widened at base and apex, the basal angles fuscous. Corium densely but finely pilose, the lateral margins 
broadly pale luteous, widening on each side towards the cuneus, which is also pale luteous. Membrane 
pale smoky ochraceous. Body beneath and legs pale ochraceous; sternum with a submarginal fuscous line 
on each side ; abdomen with a marginal series of small fuscous spots ; intermediate and posterior femora 
also spotted with fuscous, the last most prominently. 
Long. 8-10 millim. 
Hab. GUATEMALA, Quezaltenango, Volcan de Agua (Champion). 
3. Miris roseus, n. sp. (Tab. XXIII. fig. 20.) 
Body above purplish red. Antenne fuscous, the basal joint not prominently pilose. Head with a broad central 
longitudinal luteous fascia, and a fuscous, but narrower, fascia on inner side of eyes. Pronotum ochraceous, 
coarsely and darkly punctate, anterior area with two purplish rugosities on each side; the anterior and 
lateral margins and a central longitudinal line levigate and pale luteous. Scutellum with the basal angles 
fuscous, and with the apex luteous*. Corium and cuneus with the lateral margins pale luteous; the clavus 
punctate, with its outer margin luteous. Membrane pale smoky hyaline. Body beneath and legs ochra- 
ceous ; margins of head and sternum broadly purplish; central base of head and a broad central fascia to 
sternum dark fuscous; abdomen with a submarginal stigmatal purplish fascia on each side, and the base 
* Owing to the scutellum being mutilated by the pin which impales it, a further description is impossible,
