BB. Areoles in more than one series at some part of the costal margin. 

 C. Two series of areoles extending about as far as apex of pronotal 



extension costata Parshley. 



CC. Two series of areoles in all but the posterior fourth or less of 



the costal margin elliptica n. sp. 



AA. Costal margin not explanate, deflexed; subcostal area forming outer 

 anterior margin of hemelytron. 

 D. Length over 2}^ mm.; third joint of antenna nearly four times as 

 long as basal joint, total length of antenna nearly i mm., 



mutica Say. 



DD. Length less than 2j/^ mm.; third joint of antenna distinctly less 



than four times 'as long as basal joint; total length of antenna 



.75 mm. or less brevicornis Champion. 



Leptoypha minor n. sp. — Length* (excluding antennse) 1.81-1.82 mm.; 

 length of pronotum, 1.05-1.08 mm., width, .72-79 mm.; greatest width of 

 elytra, .84 mm.; length of antennal joints: i, .099 mm.; 2, .13 mm.; 3, .39^ 

 mm. ; 4, .23 mm. 



Form elliptical; antennse rather short and thick, upper surface coarsely 

 punctured ; punctures not arranged in definite rows except on uniseriate 

 costal margin. Three short blunt spines on front and two straight ones 

 from back of vertex along inner eye margins close to surface of head. 

 Median carina of pronotum distinct; lateral carinae obsolete. 



General color light reddish brown, more or less infuscated as follows : 

 Apical joints of antennse; head black, vertex, inner orbit's, and two closely 

 applied spines with short silvery hairs; region of pronotal callosities; 

 faintly on disc of pronotum and an indistinct U-shaped mark (base for- 

 ward) on posterior half of pronotum ; an irregular band of irrorations 

 across elytra through the posterior half of discoidal areas and another 

 across membrane before apex. Spines on head, edge of rostral sulcus, 

 collar and membrane distinctly lighter than ground color. Ventral surface 

 deeply infuscated on pleurae, mesosternum and most of venter. Legs light 

 reddish brown ; tarsi dark. 



Similar, to L. costata Parshley but much smaller. These two 

 species have more extensive dark markings than is usual in the 

 other species here treated. 



L. minor is easily distinguished by its size, and by the posses- 

 sion of distinct and reflexed though narrow costal margins, in all 

 parts of which there is but a single series of areoles. 



Type. — A male from Siskiyou Co., California, collected in 



* Measurements taken with eyepiece micrometer with combination of 

 eye-pieces No. i and objectives A2 in Zeiss Binocular Microscope; magni- 

 fication 20.
