somewhat dusky, stigma and ner\uires pale sepia; alHinmcn orange- 
ferruginous, without markings above or below, hair at ajicx pale 
ochreous. 
Habitat: Claremont, California {Raker; Pomona coll. 227 
part). Unfortunately the habits of this remarkable bee are un- 
known. Glnssopcrdila could be considered a subgenus of Pcrd'ita, 
but it seems distinct enough to deserve generic rank. 
The other specimens collected by Baker at Claremont sent under 
227, are marked as from flowers of Rhus latir'nui. They consist of 
Pcrdita rhnis Ckll., and a single male P. hypnxautha Ckll., the lat- 
ter presumably a stray, as the species is attached to Adenostoma. 
Also under 227 is a female of P. alhipenuis Cress., collected by 
Baker at Los Angeles, and bearing his number 691. 
Pcrdita nificauda, sp. n. 
5 Length about 5.5 mm., moderately robust, pubescence scanty; 
head and thorax dull oli\-e green; head ordinary, inner orbits paral- 
lel; mindibles pale yellow suffused with reddish, the apex black; 
clypeus black, sparsely punctured, with a broad pale yellow median 
band, failing below; no supraclypeal mark; lateral marks pale yel- 
low, trianeular, produced abo^'e. ending in a sharp point on orbitnl 
margin at le\el of antenna' ; flaffellum pale fulvous beneath; tuber- 
cles vello^^• w'xth a dark dot, and a pair of cuneiform yellow marks 
on upper border of nrothorax; mesooleura shinino-; legs piceous, 
w\th anterior a?id middle knees, tarsi and tibia^ yellow, the latter 
dark behind; tesukT pellucid; wings faintly reddish, stifrma and 
ner\'urcs reddish-brown; stigma small and slender; marLrinal cell 
Inrtre, oblinuelv truncate at end; abdomen bright orange-ferrugi- 
nous abo\e and below, without markings, except a narrow dark 
stripe alone lateral maro-ins of second segment. ^Tovlth-parts not 
especially elongated; labial nalpi with first ioint about 690 microns, 
the other three totrcther about 290 microns. Maxlllar\- palpi long 
and well-developed. 
HaJt'ital: Claremont. California (Baker: Pomona coll. 229. 
199). This superficially resembles GInssnpcrdita. Tn mv tables 
of Pcrdita it falls near P. chamaesaraclue, from which it is at once 
known by the face-marks anti the palpi.
