54 NOTES ON JAMAICAN HEMIPTERA 



abundant at Mandeville but I took them also at Balaclava, St. 

 Margaret's Bay, Hope Bay, Richmond and Kingston. These 

 are all smaller than the species as found in the United States, 

 {2% to 3 mm.), the clypeus is narrower toward the apex, and 

 the sinus of the last ventral segment of the female is much more 

 shallow with the outer apical angles more produced, forming a 

 prominent blunt tooth. The colors vary as widely as in our 

 northern form but the dark males differ from the northern 

 males in having the disk of the pronotum before the middle 

 marked with a more or less extended pale spot bisected by a 

 rather broad black longitudinal line. In novella- from the 

 United States there is a narrow black median line bordered 

 either side by pale which may be so extended as to cover nearly 

 the whole surface. In the dark Jamaican males the elytra are 

 almost black with a costal area, broadest at the middle, the 

 claval suture, an oval spot at its base, an elongated angular 

 mark on the claval commissure near its apex and the claval 

 surface within the inner nervure, pale yellow, or subhyaline on 

 the costal area. In even the palest females the rounded apex 

 of the clypeus, the lateral sutures of the front and clypeus, the 

 antennal pits, two dots on the vertex, two on the disk of the 

 pronotum, and the basal angles of the scutellum are black; the 

 frontal arcs, the sutures of its base with an abbreviated median 

 line from its angle, a spot on the ocelli, the median line on the 

 pronotum anteriorly and a cloud on its anterior margins behind 

 the eye are ferruginous, and in darker examples become black. 

 In the paler examples the elytra are yellowish hyaline, faintly 

 smoky at apex, with pale nervures, between which are indica- 

 tions of fuscous lines. 



The study of material from intermediate localities may 

 make it advisable to raise this form to specific rank but its 

 present assignment will serve to show its affinity with novella. 



Agallia lingula n. sp. 



Allied to novella but with the vertex perhaps a little more angulated 

 and the pronotum shorter. Front a little broader than in novella with the 

 sides more strongly arcuated, the basal sutures meeting in a more obtuse 

 angle, and wanting the. short median line running from the apex of the 

 angle toward the hind edge of the vertex ; clypeus a little shorter and more 

 ovate and the lorae broader than in the Jamaican form of novella. Last 

 ventral segment of the female short, truncated, with a slender ligulate pro- 

 cess, fully as long as the basal, portion of the segment; plates more slender 

 than in novella, their sides parallel and apices acute. Length scant 3 mm.
