agrees with the description, except that the scape is black, 
not yellow, and there is a broad dark brown band across the 
occiput. Noteworthy features are the thick ferruginous 
flagellum, the canary yellow face (with a little black band 
down each side of supraclypeal area and extending a little 
way down sides of clypeus), the dark mesothorax with two 
yellow bands, the yellowish wings with large pale orange 
stigma, the basal nervure falling considerably short of nerv- 
ulus, and the abdomen with alternate bands of black and 
yellow. The legs are yellow, the hind femora and troch- 
anters black beneath. The nearest relative appears to be 
0. mexicanus Cresson. 
I have a note that Radoszkowsky’s figure (not now avail- 
able to me) shows a very short marginal cell, but Friese 
examined the type in the Berlin Museum, and found it to 
be an Osiris, as indeed the description sufficiently indicates. 
It was considered to represent a new genus Euthyglossa. 
Anthidiellum apicale (Cresson) 
One female; Amapala, Rep. Honduras, March 29, 1931 
(D. M. Bates). Described from Mexico, as Anthidium api- 
cale. 
Stelis ( Protostelis ) costaricensis Friese 
One female ; Moca near Guatalon. It differs slightly from 
Friese’s description, based on specimens from Costa Rica, 
in that the venter of abdomen is entirely black, the first ter- 
gite has a slender transverse yellow stripe on disc, while the 
second has no yellow on disc, but a yellow spot (cuneiform 
in shape) at each side. The second recurrent nervure goes 
nearly as far beyond second cubital cell as the first is from 
the base of that cell. 
Halictus sericeus Friese 
One female ; Sa. Emilia near Pochuta. Friese described 
this from a female collected at San Carlos, Costa Rica. The 
description agrees so closely with the Guatemala specimen 
that I cannot doubt the identity, though the hair at end of 
abdomen is pale fulvous rather than brown, and the hind 
tibiae have pure white anteriorly.
