48 NOTES ON JAMAICAN HEMIPTERA 



March 25th. These are tiny little things measuring scarcely- 

 more than a millimetre in length. In the color and characters 

 of the vertex, pronotum, scutellum, antennae and legs they 

 agree with them exactly except that the lateral carinas of the 

 pronotum are much more strongly divergent as is usual in the 

 brachypterous forms. The elytra, which are considerably 

 shorter than the abdomen, are smoky with the margins whitish 

 hyaline interrupted by a conspicuous black mark on the apex of 

 the clavus, and with the hyaline border sometimes expanded 

 over the . basal field of the clavus. In the solitary female 

 example the elytra are nearly hyaline with a fuscous cloud fol- 

 lowing the claval suture and returning around the apical mar- 

 gin, and the lower surface of the abdomen is mostly testaceous- 

 yellow, It may seem strange to place this insect as the 

 brachypterous form of a species nearly twice its size and I do so 

 with some misgivings, but most of their characters are similar 

 and the moist mountain habitat of the larger form may account 

 for the difference in size. 



Liburnia hurnilis n. sp. 



Macropterous form : Pale brownish testaceous. Eyes, tarsal claws, 

 oviduct of the female and abdomen of the male in large part black; elytra 

 subhyaline, nervures testaceous becoming fuscous toward the apex. Vertex 

 subquadrate, deflected before, basal fovse hardly distinguished, apical very 

 small. Front moderately wide, a very little broader toward the apex which 

 is feebly angularly emarginate at the clypeus. Antennae rather long; second 

 joint much longer and broader than the first, distinctly crenulated on the 

 edges, apex of the first joint slightly embrowned. Pronotum short with the 

 hind margin strongly, angularly concave, lateral carinse strongly curved. 

 Scutellum large, deeply sinuated on the sides, lateral carinas nearly parallel, 

 placed near together, tip broad and obtuse. Elytra as in pellucida. Length 

 to tip of the elytra 3 mm. 



Brachypterous form: similar to the macropterous but with the front 

 somewhat broader toward its apex and the lateral carinae as usual more 

 strongly divergent. Length 2 to 2^ mm. 



Pygofers of the male quite deeply excavated below, the sides sinuated; 

 plates broad, strongly arched and almost meeting above near the anal tube. 



Described from five macropterous examples representing 

 both sexes taken at Mandeville, and seven brachypterous speci- 

 mens from Rock Fort. This plainly colored little species may 

 be distinguished by the large tibial spur, the broad straight 

 uncolored front and the large second antennal joint.
