sharp, not wholly decumbent, ones from back of vertex along inner mar- 

 gins of eyes. 



General color stramineous to light reddish brown ; eyes and callosities 

 black; basal and apical joints or whole antennae infuscated; veinlets across 

 discoidal region of hemelytra (especially on costa) and on membrane more 

 or less embrowned. Head spines, margins of rostral sulcus, and collar 

 paler than ground color. Spots on pleurae below callosities and mesoster- 

 num darker than remainder of lower surface. 



This, the largest of the species here considered, has a very 

 wide costal area in which there are two full series of large 

 areoles from humerus to or nearly to the point where elytron 

 begins to curve to form the apex. 



Several specimens, labelled simply Texas, in the National col- 

 lection, of which a male is selected as type. Mr. Heidemann's 

 cabinet name is discreta.

Length of an average specimen (excluding antennse), 2.9 mm.; length 

 of pronotum, 1.35 mm. ; width, .98 mm. ; greatest width of elytra, .99 mm. ; 

 length of antennal joint's: i, .13 mm.; 2, .099 mm.; 3, .49 mm.; 4, .23 mm. 



Form oblong, a little constricted across bases of elytra and somewhat 

 narrowed behind. Surface coarsely punctured ; areoles in subcostal area 

 tending to be arranged in three series; a single series of large areoles on 

 membranal margin, merging into the uniseriate costa which can be seen 

 from above only to a point just short of widest part of hemelytra. Me- 

 dian pronotal carina distinct, lateral ones traceable, if at all, only on pos- 

 terior extension. Spines on front of vertex convergent, appearing almost 

 fused, short, sometimes nearly obsolete, spines from back of vertex decum- 

 bent along inner orbits, of variable length, sometimes reaching front of 

 eyes. 



General color usually reddish brown, pruinose at various points, espe- 

 cially on head and anterior part of thorax. Eyes dark, callosities black ; 

 veinlets infuscated about discoidal areas and on membrane. Cephalic 

 spines, collar and disc of membrane paler. Some specimens are very prui- 

 nose, even the antennae being covered, while others become very dark, 

 sometimes almost black. The areas which most persistently remain light 

 are collar, apex of pronotal extension, and areas at humeral and cuneal 

 portions of elytra. Lower surface usually of uniform ground color except 

 for pale rim of rostral sulcus, and scattered pruinosity. 



In L. mutica and L, brevicornis the costal area, according to the point 

 of view, is obsolete or defiexed anteriorly. The species are therefore more
