some Oenera of Bees. 2H1 



Heriades truncorum (L.). 



Lahiul palpi. — 1 much sliorter than 2. 

 Maxillarij jio-^pi 3-jointed. 



Chelostoma campanalarum (Kirby). 



Labial palpi. — 1 extremely short, 2 very long; last juuit 

 only diverging from the straight line. 

 Maxillary palpi 3-jointed. 



Phileremus mesilloij Ckll. 



Labial pilpi. — 1 longer than 2; palpi shorter than in 

 Dioxys productus) 3 + 4 more than half length of 2. 



Tongue very broadly fimbriate, the lateral fiinbiitc towards 

 the tip longer than breadth of tongue at that point. 



Maxillary palpi 2-jointed ; 1 a low broad tubercle, 2 long- 

 oval, rather large. The pulpi look as if 1-jointed. 



Galea. — Comparatively short and broad, broadly rounded 

 at end, inner margin not ciliate ; stri^ longitudinal. 



The galea is wholly unlike that of Coelioxys^ MerjachUe, 

 IHoxys, &c., and resembles that of Epeolus. It seems likely 

 that this and the Epeolus-Vike outward appearance of the 

 bees are indications of real relationship. 



This appears to fall in Phileremus as defined by Taschen- 

 berg, but it is by no means an Ammobates, of whicii Phile- 

 remus has been lately regarded a synonym. It accordingly 

 finds no place in Ashmead's tables. 



Coclioxys fjilensis, Ckll. 



Labial palpi. — 1 shorter than 2 ; 3 + 4 not half length of 2. 



Maxillary palpn 3-jointed ; 1 a rounded tubercle ; 2 broad, 

 subquadrate viewed laterally; 3 rather small but stout. 



Galea. — Long-falciform ; strije oblique, decussating ; inner 

 margin ciliate. The mouth-parts confirm the view that this 

 genus is closely related to Megachile. 



Megachile apicalis, Spinola. 



Labial jial pi. — 1 and 2 about equal, very much broadened, 

 each with a row of strong bristles. 



Maxillary jtalpi 'd-jointed ; 3 much longer than in Cwlioxys. 



Galea. — Broad and tapering, with a margin on each side 

 of the double rib. I'he inner area is rather narrow, decus- 

 sated, and strongly ciliated on the edge ; the outer area is 

 broad, plain (not striated), and its edge is not ciliated. The 

 rib bears a row of long bristles and shuws some hyaline dots.
