August ; allotype female with same data. Both in collection of 

 U. S. National Museum. I am adopting Mr. Heidemann's cabi- 

 net name for this species. 



Leptoypha costata Parshley. — Leptoypha costata Parshley, H. M. Psyche, 

 24, No. I, February, 1917, pp. 16-17 (Marshall Hall, Md.) ; Leptoypha dis- 

 tinguenda Heidemann, Otto. Proceedings of the Entomological Society 

 of Washington, 18, No. 4, Dec. 1916 (June 1917), PI. 17, Fig. i, p. 218 

 (Washington, D. C, Rock Creek, D. C, Marshall Hall, Md., Mf. Ver- 

 non, Va.). 



Length of a well-developed male specimen (excluding antennae), 2.83 

 mm.; length of pronotum, 1.38 mm.; width, 1.05 mm.; greatest width of 

 elytra, 1.1 mm.; length of antennal joints: i, .13 mm.; 2, .16 mm.; 3, .57 

 mm. ; 4, .22, mm. 



Form oblong elliptic, hemelytra expanded across discoidal areas and 

 rather narrowed toward apex. Body surface coarsely punctured, the 

 areoles not in definite rows except in costa and margin of membrane. 

 Percurrent median and shorter lateral carinse on pronotum distinct. Three 

 short converging tubercles on front and two rather long curved spines 

 from back of vertex reaching past middle of eyes. 



General color reddish brown, eyes black, cephalic spines pale. Region of 

 pronotal callosities, indistinct clouding on remainder of pronotum and 

 irrorations across discoidal, and central membranal areas of the elytra 

 fuscous. Lower surface darker than upper ; infuscated on pleurae, pectus, 

 and sides of abdomen. In pale specimens the collar, lateral margins of 

 pronotum, apex of pronotal extension, and costa are distinctly lighter than 

 the ground color. 



This species has a distinct, reflexed costal margin of moderate width in 

 which there are two series of areoles from humerus nearly to point where 

 greatest width of elytron is attained, and a single series for the remainder 

 of the length. The lateral carinse of pronotum are more conspicuous than 

 usual, being readily traceable from point just back of callosities to pos- 

 terior margin of pronotum. 



The only specimens thus far seen are those cited in connection 

 with Mr. Heidemann's description. 



Leptoypha elliptica n. sp. — Length of an average male specimen (exclud- 

 ing "antennae), 2.93 mm.; length of pronotum, 1.32 mm.; width, .92 mm.; 

 greatest width of elytra, 1.22 mm.; length of antennal joints: 1, .13 mm.; 

 2, .099 mm. ; 3, .89 mm. ; 4, .33 mm. . 



Form broadly elliptical ; hemelytra unusually expanded at middle, broadly 

 rounded at apex. Body coarsely punctured; the areoles in regular rows 

 only on costa and margin of hemelytra; median pronotal carina distinct; 

 lateral ones barely traceable on pronotal extension. Three short but sharp, 

 and convergent, almost fused spines on front of vertex, and two short,
