Genus Macrotyloides, n. gen. 



Elongate, ovate, widest near apex of clavus. Head strongly 

 produced, subhorizontal, with eyes as wide as pronotum at trans- 

 verse incisure and a little more than half its basal width, its 

 length about equal to the median length of pronotum. Vertex 

 sometimes flattened or impressed before the base, leaving the 

 edge obtusely prominent, but scarcely carinate as in OrtJwtylus. 

 Vertex and front together when viewed from above scarcely 

 longer than wide, but slightly convex. Clypeus prominent, 

 arcuated before, its base well distinguished from the front and 

 on a line with the antennal sockets. Inner cheeks prominent, the 

 outer narrow. Eyes rather small, their inner margins feebly 

 divergent; viewed from the side oval, a little oblique, reaching 

 over half-way to gula ; gula nearly horizontal. Antennae long, 

 inserted close to lower angle of eyes, first joint with two setae 

 within near their apex. Rostrum long, attaining middle of 

 venter. Pronotum trapezoidal, its anterior margin about halE the 

 posterior ; sides rectilinear, obviously carinated ; callosities large, 

 little elevated. Basal lobe of seutellum exposed. Prosternal 

 xyphus Math margins carinate. Elytra rather short, with costa 

 quite strongly arcuated. Wing-cell without a hamus. Legs rather 

 long; tibiae with short, feeble bristles. Hind tarsi linear, joints 

 but slightly distinguished, basal shorter than the other two, 

 which are subequal ; claws short, arolia rather large, free and 

 connivent, not equalling the claws. Vestiture not very dense, of 

 soft white hairs sometimes intermixed with stifPer fuscous ones. 



Type of the genus Macrotyhis vestitus Uliler. 



This genus includes rather large green Capsids suggesting 

 Lahopidea Uhler, but with smaller eyes and a produced oblique 

 head as in Macrotylus ; the tylus less prominent and the claws 

 large, with their arolia free and approaching at apex. AVhen 

 the elytra are closed the body is conspicuously narrowed both 

 before and behind. Our species may be distinguished as follows : 



Membrane about equally and lightly infuscated vestitus Uhl. 



Membrane with the apex abruptly fuscous apicalis u. sp. 



Macrotyloides vestitus i Uhler) 



Long ovate, narrower before; pale grass-green, becoming 

 yellowish when dry ; membrane very faintly and uniformly en- 

 fumed. Length 5 to 6 mm. 



Head nearly horizontal. Vertex hardly flattened, more than 

 twice as wide as the eyes in the male, its basal margin appearing 

 a little thickened in some individuals; front, feebly convex
