laterad of the metascutellum ; antennal segments i and 2 marked with 

 white; fore femora marbled dorsally with white; femora of second 

 and third pairs and all tibiae, with an apical white blotch. General 

 color (by transmitted light), blackish brown, with maroon hypodermal 

 pigmentation; antennal segments i and 2 nearly concolorous with body; 

 segments 3 and 5 yellow, the former clouded near apex with gray ; 

 segments 4, 6, 7 and 8 nearly black, 4 and 6 with their pedicels yel- 

 low ; extremities of tibiae nearly transparent. 



Head about as wide as long; 

 cheeks swollen, dorsal and lateral 

 surfaces with many short sub- 

 clavate spines; postocular bristles 

 wanting. Eyes reniform, finely 

 faceted. Ocelli present, moderate 

 in size. Antennae about one and 

 three-fourth times as long as 

 head ; fully developed sense cones 

 on segments 3 and 4 large, stout ; 

 those on segments 5-7 moderately 

 slender; formula*: 3, o-i ; 4, 

 i-i i; 5, i-i 1; 6, i-i 1; 7 with 

 one on dorsum near apex ; seg- 

 ments 1-3 with infundibuliform 

 bristles. Mouth-cone large, attain- 

 ing base of prosternum; labium 

 broadly rounded and slightly sur- 

 passing the labrum, which is nar- 

 rowed at apex. 



Prothorax nearly .6 as long as 

 head, and (including coxae) about 

 2.4 times as wide as long; spines 

 dilated apically, scarcely visible.! 

 Pterothorax wider than prothorax 

 and slightly wider than long; sides 



subparallel for half their length, then roundly converging to base of 

 abdomen. Wings present, reaching base of tube. Legs rather short 

 and stout; fore tarsi armed with a small acute tooth. 



*The explanation of the formula for the antennal sense cones has 

 been given in Ann. Ent. Soc. Am., Vol I, No. 4, p. 285, and in Ent. 

 News, Vol. XX, No. i, p. 29, foot note. 

 6, i-i 1 ; 7 with one on dorsum near apex; segments 1-3 with infundi- 



fThe prothoracic bristles are so nearly transparent that they can be 

 seen only after a very careful adjustment of the light. In the figure, 

 the bases of several have been shown, although the bristles themselves 

 could not be made out.
