beyond the middle. In the other extreme the elytra are 

 hyaline with a fuscous ray through the middle from base to 

 apex toward which it is more or less extended inwardly, nerv- 

 ures punctate. 



The only female in the lot differs in being fuscous in place 

 of black, with the narrow edges of the pleural and ventral seg- 

 ments, hind edge of the pronotum, carinae of the vertex, prono- 

 tum and scutellum, and the cheeks, pale. Antennae and legs 

 yellow as in the male. 



Liburnia albolineosa Fowler. (Op. cit. p. 135, pi. 13, fig. 14.) 

 I took three examples of this pretty species at Kingston. 

 Two of these were swept from a patch of a fine grass growing 

 m a damp railroad ditch. Fowler's description of this species 

 is very inadequate but his figure is excellent and leaves little 

 question about the identity of the species. There seems to be 

 much variation in the amount of black on the elytra. In one 

 example the whitish hyaline areas on the clavus and apex of the 

 costa are so extended as to cover most of the surface. In all 

 my specimens the deflected sides of the pronotum are pale yel- 

 low* and the frontal carinas are blackish for most of their length. 



Liburnia culta n. sp. 



Allied to pellucida. Black, somewhat polished; facial carinas, slender 

 margin and carinae of the pronotum, apex of the scutellum, commissure of 

 the elytra on the basal half of the clavus; basal fovee of the vertex, carinae 

 and slender margins of the scutellum, nervures of the elytra in part, antennae 

 and legs, testaceous. 



Vertex as in pellucida, almost square, scarcely produced before the 

 eyes, rounded to the front, the apical triangular fova more acute and elon- 

 gated. Front narrow, sides almost parallel, fovae deep black; second joint 

 of the antennae hardly longer than the first, scarcely expanded, almost 

 smooth. Pronotum as long as in pellucida, the lateral carinae less oblique, 

 the included area more or less invaded with white. Scutellum a little 

 shorter, more convex, with a more slender apex and less distant carinae. 

 Elytra almost hyaline, a little smoky toward the base and interiorly at apex, 

 the nervures mostly pale becoming blackish along the disk of the corium 

 and toward the apex of the clavus, punctate and forked as in pellucida. 

 Abdomen piceous, touched with pale along the margins and on the edges 

 of the segments in places; the metapleura largely pale. Length to tip of 

 the elytra 3^ mm. 



Described from two macropterous females swept from a 

 cultivated field at Mandeville, March 31st. 



Another form that I believe to be the brachypterous form 

 of the above I took in both sexes at Rock Fort near Kingston,
