172 HEMIPTERA-HETEROPTERA. 
Division SERINETHARIA. 
Serinetharia, Stal, En. Hem. iii. p. 97 (1873). . 
In this division the anterior portion of the lateral margins of the pronotum are 
distinctly and angularly emarginated, a character which will alone separate the 
_ Serinetharia from the Corizaria. Three genera are included, two of which are here 
enumerated; the third, Serinetha, is found in the Ethiopian, Oriental, and Australian 
Regions. 
LEPTOCORIS. 
Leptocoris, Hahn, Wanz. Ins. i. p. 200 (1831). 
Pyrrhotes, Westwood in Hope, Cat. Hem. ii. p. 6 (1842), ad partem. 
Serinetha (part.), Spinola, Ess. Hém. p. 247 (1837) ; Dallas (part.), List Hem. i. p. 459 (1852). 
A reference to the diagnostic characters of the following genus will serve to separate 
_ Leptocoris. 
But one species is known from Central America, and is recorded from Mexico. 
1. Leptocoris trivittatus. 
Lygeus trivittatus, Say, Journ. Acad. Philad. iv. p. 822. 2°; Compl. Writ. ii. p. 246. 2. 
Leptocoris trivittatus, Stal, En. Hem. i. p. 226.1; Uhler, Hayden’s Surv. Mont. pt. iv. Zool. & 
Bot. p. 404°; Bull. U.S. Geol. & Geogr. Surv. ii. p. 8301‘; ib. iii. p. 408; Town. Glover, Ill. 
Ins. Ord. Hem. p. 438, t. iv. f. 24. 
Hab. Norta America, Missouri! 4, Kansas +, California * 4 (coll. Dist.), Colorado ° 4, 
Arizona ? #.—Mexico 2 4, 
Of this species Prof. Uhler remarks that, although very common in Arizona and 
Califcrnia, he did not find many specimens in Colorado. In the month of August he 
met with it at the roots of cacti and yuccas. 
JADERA.

p. 99 (1873)?. 
Stal? thus abstracts his diagnosis of this genus :—‘ Bucculis basin capitis attingentibus; 
segmento ventrali sexto feminarum mihi cognitarum apice truncato.” Of seven recorded 
species three are found in Central America. 
1. Jadera obscura. (J. lateralis, Tab. XV. fig. 21.)
