44 NOTES ON JAMAICAN HEMIPTERA 



Macrotomella n. g. 



Form broad and stout. Head broad, considerably narrower than the 

 mesonotum. Vertex short, strongly declivous, rounded to the base of the 

 front. Front broad; middle keel forked for its entire length the two 

 branches passing over on to the vertex where they are curved outwardly and 

 meet the lateral keels at the hind margin; clypeus tricarinate. Antennae 

 short, basal joint not longer than broad. Pronotum tricarinate, about as 

 long as the vertex, truncated behind, lateral carinas very oblique, straight, 

 reaching the hind edge much exterior to the scutellar carinas. Scutellum 

 rather short, tricarinate. 



This genus seems to be most nearly related to Jassideus 

 but the vertex is not at all five angled, being truncated before, 

 and the lateral carinae of the pronotum attain the hind margin. 

 All the carinae are strongly distinguished. 



Macrotomella carinata n. sp. 



Yellowish testaceous; carinae of the head, pronotum and scutellum 

 white, bordered with black; deflexed sides of the pronotum deep velvety 

 black narrowly edged with white; pleural pieces with some brown spots. 

 Legs lineate with brown which becomes black on the outer face of the 

 tibiae. Abdomen black marked with pale on the venter. Elytra whitish 

 hyaline; nervures slender punctured with brown, the apical margin slenderly 

 brown. Wings almost as long as the elytra, whitish hyaline; apical nervure 

 brown, discal slender and white. 



Vertex almost square, scarcely surpassing the eyes; carinae very prom- 

 inent, basal fovas obsolete but in their place a short median carina. Front 

 broad, sides well rounded, disk divided into three almost equal compart- 

 ments by the forked median carina. Median carina of the pronotum con- 

 tinuous with that of the vertex; lateral running parallel with the hind mar- 

 gin of the eyes. Sides of the scutellum rather deeply arcuated; lateral 

 carinas moderately divergent. Elytra but little longer than the abdomen. 

 Oviduct of the female not exceeding the pygofers, pale. 



Described from four macropterous females taken at Rock 

 Fort near Kingston, March 25th. 



Pissonotus delicatus Van Duzee. 



This species was described from a single brachypterous 

 female from California. Later 1 received a fine series of 

 macropterous and brachypterous females from Mr. Howard E. 

 Weed taken at Agricultural College, Miss., and have myself 

 taken the brachypterous females at Grand Junction and Pueblo, 

 Colorado, Riverton, N. J. and Washington. D. C. All those 

 from Colorado and Mississippi have the apex of the head con- 

 col orous, the basal joint of the antennae in part black, and the 

 femora lineated with brown. Those from New Jersey are 

 darker in color with the abdomen piceous, but do not differ
