502 HEMIPTEROIvOGICAI, GLEANINGS 



2, Lamenia obscura Ball. 

 Can. Ent. xxxiv, p. 262, 1902. 

 A widely distributed species differing from vulgaris in 

 being- smaller, in having the vertex shorter with the frontal 

 carinae less prominent over the apex of the head, and the hind 

 margin of the pronotum more deeply subangularly emarginate. 

 Usually the carinae of the head and pronotum are all more or 

 less distinctly pale. The base of the front has a transverse 

 carina in this species but it is less conspicuous than in vulgaris. 

 In some males of this species there is a distinct reentrant angle 

 on the inner margin of the plates but I cannot otherwise dis- 

 tinguish them. In the more typical examples these margins 

 are almost straight and approximate except for a short space 

 at base. The last ventral segment of the female is shorter and 

 more rounded at apex with the sides feebly sinuated near the 

 basal angles. 



My material for this species is from Me., Mass., N. Y., 

 N. J., N. C, Fla. and Kansas. 



3, Lamenia californica Van Duzee. 



Can. Ent., xxm. p. 169, 1891. 



This species is about the size of obscura but is distinct in 

 having the head, pronotum, pectus and legs pale yellowish tes- 

 taceous. The inner margins of the male plates are excavated 

 so they meet only at base and tip. The types were from Cali- 

 fornia but Mr. H. G. Barber has recently sent me a specimen 

 taken at Phoenix, Ariz., July 25th, 1902. It probably occurs 

 throughout the hot arid regions west of the Rocky Mts. 



4, Lamenia prascox n. sp. 



Near vulgaris but a little smaller with the head, pronotum, 

 mesonotum and pectus fulvo-testaceous. Length \y 2 mm. 



Vertex broader than in vulgaris with the frontal carinae more prom- 

 inent over the apex. Front very little contracted at base, median carina 

 nearly obsolete, lateral laminate above. Pronotum a little longer than in 

 the allied species, the anterior and posterior margins parallel, regularly 

 arcuated. Plates of the male meeting only at the middle, strongly retreat- 

 ing to their base and apex, their apical hooks slender and a little curved 

 upward. Color smoky black, pruinose ; head, pronotum, mesonotum, entire 

 pectus and edges of the abdominal segments fulvo-testaceous or inclined 

 to ferruginous. Legs pallid becoming greyish or brownish on the tibiae 

 and anterior femora; apex of the rostrum and tips of the tarsal joints 

 blackish. Transverse veinlets at the base of the apical elytra! areoles white. -
