angle, set on a paler spot. Pleural pieces fuscous, bordered 

 with pale yellow, the sternal segments and coxae greenish 

 yellow. Legs piceous, minutely pubescent, pale yellow on the 

 knees, tip of tibiae and tarsi. Wing-covers blackish piceous, 

 with a large hyaline spot at the basal inner angle, a hyaline 

 band, widening exteriorly, behind the middle, a shorter band 

 of like color next the tip of membrane, and the marginal 

 expanded border likewise hyaline with the cross veins mostly 

 invaded by brown stains ; veins dark brown, but generally 

 paler, or interrupted with pale piceous where crossing the pale 

 bands. Ventral segments more or less widely bordered with 

 greenish yellow, tergum with a yellow dorsal line of interrupted 

 marks and with series of obscure spots each side. 



Length to tip of wing-covers ? 5, 6 millims. To tip of 

 venter 9 4J-5 millims. Width of pronotum 2 millims. 



Five specimens have thus far passed through my hands, and 

 most of these were captured by Mr. Coquillett in the vicinity of 

 Los Angeles, Cal. A single specimen, labelled simply Cali- 

 fornia, was sent to me by Mr. Henry Edwards. 



I have failed to observe wings in any of the foregoing genera 

 or species. 



Dictyonia. New genus. 



Blunt and wide; wing-covers transparent, carried almost 

 vertical, as long as broad, flat, wide, ovoid, with exceptionally 

 few and large areoles. Head blunt, subtruncate, set so deeply 

 that the eyes almost touch the base of the wing-covers ; vertex 

 transverse, very short, carinate on the anterior margin, the pos- 

 terior margin more prominently carinate and broadly sinuated, 

 surface sunken, indented each side ; front a little curved, 

 middle line with a blunt carina, and the lateral margins dis- 

 tinctly carinate, inferior margin deeply sinuated, the epistoma 

 strongly convex. Pronotum bluntly lunate, depressed, a little 

 longer than the vertex, enclosed each side by the eyes. Scu- 

 tellum short, triangular, somewhat sinuated each side. Tibiae 

 grooved and carinate edged as in Neaethus, the posterior pair 

 with spines exteriorly, and the posterior tarsi depressed, with 

 the angles of the two basal joints produced into spines. Wing-
