on account of its less-stalked abdomen, which, moreover, lacks 

 the lateral black spots. 



Panay, Antique Province, Culasi (McGregor), June, 1918. 

 Type, a single female specimen, in my collection. 



Female. — Length of body, more than 9 millimeters; of ovi- 

 positor, 1.5 ; of wing, 8. Occiput of a shining, pale reddish color, 

 with a broad, pale-yellowish border. Frons parallel-sided, one 

 and one-half times as long as broad, opaque, with shining ver- 

 tical plates; dirty reddish with yellow sides, a broad, rounded, 

 darkish spot, clothed with erect pubescence on its front half; 

 dark orbital spots indistinct ; lunula very broad, shining reddish 

 yellow. Face short and broad, flat in the middle but prominent 

 at mouth border, shining yellow, with a broad black spot on in- 

 ner apical side of each antennal groove; cheeks rather broad; 

 jowls broader than breadth of third antennal joint. Antennae 

 with third joint wanting in the type, but to judge from the 

 two basal joints they must be very long, much longer than face ; 

 first joint as long as elongate second joint, both yellowish in 

 color. Palpi yellowish; proboscis dirty reddish. Cephalic 

 bristles black, even the rather strong genal one; two pairs of 

 well-developed lower orbitals; postvertical short and yellowish, 

 hairlike. 



Thorax broad and robust, rather convex above; on back of 

 mesonotum punctate and clothed with proportionally long, pale- 

 yellowish pubescence; opaque black on middle, reddish in front, 

 on sides, and before scutellum. Yellow markings as follows: 

 Entire humeral calli; notopleural calli; and a broad transverse 

 stripe in front of the suture, as broadly interrupted in the middle 

 as thoracic suture. Pleura punctate and less shining, with 

 whitish pubescence; reddish, broadly black in the middle, with 

 the following yellow markings: A mesopleural stripe, con- 

 tinued with a not much larger yellow spot on upper border of 

 sternopleuron ; a double hypopleural spot. Mesophragma en- 

 tirely black like postscutellum, gray dusted, hardly reddish 

 brown in the middle. Scutellum proportionally small, punctate 

 and pubescent like back of mesonotum, yellow, with a narrow 

 brownish basal stripe; bearing only the apical pair of bristles, 

 the latter black. Thoracic bristles black, scapular bristles very 

 strong and long, even those of middle pair ; one anterior supra- 

 alar; no prescutellar ; pteropleural weaker than mesopleural. 

 Squamulse and halteres whitish. 



Abdomen rather elongate and convex ; not properly stalked at 

 base, first segment being not much restricted and not cylindrical ;
