spurred, in a line with R2+3 ; a strong cross-vein in cell R3 at about two- 

 thirds of the length of the cell ; cell ist Mg rather elongate ; basal deflec- 

 tion of Cui at the fork of M. 



Abdomen : tergum pale yellowish white, apical fourth dark brown ; 

 apex sternum similar, but the dark apex not so clearly defined.

Ç . — Head : rostrum and palpi dark brown. Antennae, basal seg- 

 ments very dark brown ; basal five flagellar segments lighter brown, apical 

 segments dark brown. Front, vertex and occiput dull gray, with a black 

 mark on vertex along inner margin of the eye. 



Thorax : pronotum dull greenish gray poUinose, with a broad black 

 stripe on the side of the scutum. Mesonotum, prsescutum dark brown, 

 thickly grayish pollinose, with a black stripe on either side of the narrow 

 median gray line, running from the anterior margin of the sclerite almost to 

 the suture. Lateral stripes short, broad, beginning behind the pseudo-

 scutum in middle and along the caudal margin dark brown ; scutellum 

 and postnotum dark brown. Pleurae black, greenish gray pollinose.

 extending down over the fork of Rs ; cells 2nd Ri and R3 with large 

 brown spots filling most of the cells ; cells R5 to Cu^ suffused with lighter 

 grayish brown and with hyaline spots ; basal and anal cells with smaller 

 brown spots ; a series of abDUt four in cell ist A. Ends of veins Cuj,

 and R yellow, except where located in the brown markings, where they 

 are black. Venation: (See fig. j.) Sc long, ending far beyond the 

 origin of Rs, but slightly before its middle ; Rs long ; basal deflection of 

 Cui far before the fork of M.
