22 Mr. T. D. A. Cockerell — Descriptions and 



each side of first segment^ aud small yellowisb-wliite tufts on 

 sides of segments 3 to 5. 



Distinguished from the North-American species by the 

 colours of the pubescence ; also as follows : — Compared with 

 P. tricolor, Franklin, it is rather less robust, and the hair of 

 the abdomen is considerably shorter ; the wings are much 

 redder; malar space shorter (its length perhaps a trifle 

 greater than width of mandibles at base, but in tricolor vi\\xc\i 

 greater) ; mandibles much more slender; third antennal 

 joint shorter ; hair of hind tibise and basitarsi very much 

 shorter, mcstly not louger than half diameter of leg. (The 

 male of the European P. quadricolor, Lep., has even shorter 

 hair on hind basitarsus, but long hair on the tibia. The male 

 of the European P. cumpestris (Panz.) has the hair on hind 

 tibia and tarsus practically as in P. guatemalensis.)

Anthophora usticauda, sp. n. 



$ . — Length about 10^ mm. 



Black; tarsi reddish at apex ; eyes green ; antennae black : 

 clypeus with a rather broad, subapical, transverse, yellow 

 band, interrupted in middle ; labrura densely and strongly 

 punctured, yellow except narrow apical margin and a large 

 spot at each upper corner ; mandibles with a large more or 

 less bilobcd yellow mark ; malar space almost obsolete ; hair 

 of face and cheeks white, stained with ochreous on front; 

 hair of vertex long and black (not going so far forward as 

 anterior ocellus), of occiput ochreous: hair of thorax above 

 mixed pale fulvous and black, at sides and behind a livelier 

 fulvous, without black, but on lower part of pleura white ; 

 ■ tegulse rufo-piceous. Wings smoky, nervures black ; ante- 

 rior femora and trochanters with long white hair behind. 

 Hair on outer side of legs fulvous (that of hind tibiae abun- 

 dant, shining), but brusii on end of hind basitarsus black ; 

 hair on inner side of middle and hind tibiae and basitarsi 

 black ; spurs ferruginous. Abdomen ornamented with 

 appressed, scale-like, rufo-piceous pile, with black hairs inter- 

 mixed ; the rufo-fulvous parts include rather narrow apical 

 nuirgiu of first segment, broader margin of second, most of 

 third except a narrow longitudinal median band and a large 

 basal area on each side, fourth except a median stripe and 

 a little space at extreme sides, fifth (the colour paler) except 

 a large black median triangle ; beneath, the abdomen has
