BBITISH HTMENOPTERA ANTHOPHILA.. 425 



seen to be set with rows of fine short golden hairs. Lingua loug, 

 not cousti-icted at the base ; on the membranous covering of the 

 upper surface of the meatum are two elongate, subparallel, narrow, 

 slightly sinuate sclerites extending almost to the junction of 

 the labial palpi ; beyond these at their apical ends are two others, 

 which diverge rather rapidly and apparently terminate near the 

 base of the lingua ; these latter seem to me to be a portion of 

 the paraglossae, and to represent the broad basal portion of those 

 organs so largely developed in the short-tongued bees ; the rest 

 of the paraglossfe, i. e. their apical portion, appears beneath the 

 membrane which invests the root of the lingua and extend as 

 two straight narrow sheath-like bodies to about the apex of the 

 1st joint of the labial palpi. Mentum beneath slightly widened 

 to the apex, three times or more as long as wide; 2tid joint of 

 labial palpi twice as long as the 1st, with its inner margin sub- 

 membranous ; 3rd and 4th very short, cylindrical. Submentum 

 very elongate and narrow ; lora short and wide ; cardines much 

 curved, and widened about the middle.

Labruin shaped much as in Goelioscys, longer than wide, with 

 nearly parallel sides and abruptly truncate apex ; epipharynx 

 hidden beneath it ; scales at the base of the maxillae stipitate, 

 their blades about four times as long as wide, parallel-sided, and 

 truncate at the apex, inner margins set with bristly hairs ; maxil- 

 lary palpi 2-jointed, blades of the maxillae as in Coelioxys, 

 and all the upper sclerites of the mentum, paraglossse, &c. 

 scarcely diftering from those of that genus ; the first joint, how- 

 ever, of th' "abial palpi is longer, almost equalling the 2nd. 

 For the me um &c. the description of Coelioxys will practically 

 apply.

In this genus again the cibarial aj)paratus is almost identical 

 in form with the preceding, but the maxillary palpi are only one- 

 jointed; and the outer half of the blades of the maxillae are more 

 deeply striate and set with stronger bristles ; the sclerites also, 

 which connect the mentum with the maxillae and form the con- 

 tinuation of the sclerites of the hypopharynx, are much curved, a 

 large portion of the curves showing on each side, and unite with
