 rufous at tip : hemelytra on the lateral and terminal margins 

 pale rufous : abdomen pale rufous on the margin : pectus, ante* 

 rior and lateral margins pale rufous. 



Length over three-tenths of an inch.

 and posterior edge sanguineous ; scutel black : hemelytra san-

 whitish : pectus and postpectus fuscous ; feet black ; venter san-

Length over one-fifth of an inch. 



Allied to hicrucis nob., but is not half so large, and the coloring 

 of the thorax is quite different. 



4. L. RECLiVATUS nob. Var. a. enotus. Destitute of the 

 white spot of the membranaceous portion of the hemelytra. 



Inhabits Mexico. 



5. L. LEUCOPTERUS [Chinch bug.] Blackish, hemelytra white 

 with a black spot. 



Inhabits Virginia. 



Body long, blackish, with numerous hairs : antennae, rather 

 short hairs : second joint yellowish, longer than the third; ulti- 

 mate joint rather longer than the second, thickest : thorax tinged 

 with cinereous before, with the basal edge piceous : hemelytra 

 white, with a blackish oval spot on the lateral middle ; rostrum 

 and feet honey-yellow : thighs a little dilated. 



Length less than three-twentieths of an inch. 



I took a single specimen on the Eastern Shore of Virginia. 



The whiteness of the hemelytra in which is a blackish spot 

 strongly contrasted, distinguishes this species readily.
