BEITISH HTMENOPTEEA ANTHOPHILA. 421 



with exceedingly short hairs. Paraglossse truncate at the base ; 

 the inner margin of the basal portion nearly straight, and almost 

 uniting over the base of the lingua ; apices produced into elon- 

 gate pointed sheaths in shape something like the maxillse. 

 Lingua elongate, a little more than seven times as long as wide, 

 finely ridged transversely, and with whorls of short bristly hairs ; 

 apex simple, with apical spoou-like lobe. Beneath, with the 

 mentum widened towards the apex, about three times as long as 

 its greatest width ; labial palpi 4-jointed, the joints narrow and 

 rounded, basal joint very long, longer than the 2nd and 3rd to- 

 gether. Submentum short, pear-shaped, and hyaline. Maxillse 

 with a tuft of long feathery hairs at the base ; lora very feebly 

 developed, formed, as in Prostopis, Colletes, &c., merely by the 

 chitinized arch of the membrane investing the space between the 

 cardines. 



The feebly developed lora and subcylindrical labial palpi, 

 associated with the long pointed paraglossae and elongate lingua, 

 characterize this genus as one of the most peculiar in our list, 

 especially when it is remembered that in the J genital armature 

 it is also unlike all its congeners.

Of this rare genus I have only one specimen with its tongue 

 extended, which only shows some of the sclerites, but they evi- 

 dently are arranged very much as in Panurgus. The maxillse have 

 some long hairs at the base ; the lingua hardly extends beyond 

 the apices of these organs. The maxillary palpi are 6-jointed ; 

 the labial 4-jointed, all of which are more or less cylindrical, as in 

 the short-tongued genera ; the basal joint is almost as long as the 

 two following together. The submentum is short and subhyaline 

 as in Panurgus, but there appears to be no thickening of the 

 membrane between the cardines at its apex, as in that genus, and 

 therefore nothing to correspond to the lora ; the cardines them- 

 selves are very long and straight.

Labrum transverse. Epipharynx triangular, somewhat rounded 

 at the apex. Maxillary palpi long, 6-jointed; blades of the 

 maxillse rather short, pointed, bearing on their surface some 

 semierect hairs, internal margin membranous. Paraglossse at the
