somewhat dusky, stigma and nervures pale sepia; abdomen orange- 

 ferruginous, without markings abov^e or below, hair at apex pale 

 ochreous. 



Habitat: Claremont, California {Baker; Pomona coll. 227 

 part) . Unfortunately the habits of this remarkable bee are un- 

 known. Glossoperdita could be considered a subgenus of Pcrdita, 

 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 Rims laiiriua. They consist of 

 Pcrdita rhois Ckll., and a single male P. hvpoxantha Ckll., the lat- 

 ter presumably a stray, as the species is attached to Adenostoma. 

 Also under 227 is a female of P. alhiponiis Cress., collected by 

 Baker at Los Angeles, and bearing his number 691. 



Pcrdita ruficauda, sp. n. 

 ? Length about 5.5 mm., moderately robust, pubescence scanty; 

 head and thorax dull olive green; head ordinary, inner orbits paral- 

 lel; mandibles pale yellow suffuseci with reddish, the apex black; 

 clypeus black, sparsely punctureci, with a broad pale yellow median 

 band, failing below; no supraclypeal mark; lateral marks pale yel- 

 low, triangular, produced abo^'e, ending in a sharp point on orbital 

 margin at level of antennre; flagellum pale fulvous beneath; tuber- 

 cles yellow with a dark dot, and a pair of cuneiform yellow marks 

 on upper border of prothorax; mesopleura shining; legs piceous, 

 with anterior and middle knees, tarsi and tibine yellow, the latter 

 dark behind; tegula? pellucid; wings faintly reddish, stigma and 

 nervures reciciish-brown ; stigma small and slender; marginal cell 

 large, obliquely truncate at end; abciomen bright orange-ferrugi- 

 nous above and below, without markings, except a narrow dark 

 stripe along lateral margins of second segment. Mouth-parts not 

 especially elongated; labial palpi with first joint about 690 microns, 

 the other three together about 290 microns. Maxillary palpi long 

 and well-cieveloped. 



Habitat: Claremont, California {Baker; Pomona coll. 229, 

 199). This superficially resembles Glossoperdita. In my tables 

 of Pcrdita it falls near P. ehamaesaraclue, from which it is at once 

 known by the face-marks and the palpi.
