THE CANADIAN ENTOMOLOGIST 407 



next four combined; hair of head entirely fulvous, very bright 

 and abundant on occiput; prothorax with dark seal-brown hair; 

 mesothorax densely punctured, covered with short, black hair, 

 which imperceptibly shades into dark brown anteriorly, the ex- 

 treme hind margin with a little ochraceous hair; scutellum and 

 metathorax covered with ochraceous hair, fulvous laterally; scu- 

 tellum dark reddish, bigibbous in middle, the bosses rounded and 

 polished, free from hair; pleura with black hair, except anteriorly 

 below, where it is long and fulvous; tegulae large and black; wings 

 fuliginous, paler and yellower basally; first r. n. meeting second 

 t. c; b. n. falling far short of t. m.; legs dark red, with rich, fulvous 

 hair; abdomen dullish, with very minute punctures and scattered 

 larger ones; surface appearing black and nearly nude (though with 

 appressed black hair on third segment) as far as middle of fourth 

 segment, but beyond that the abdomen is covered with long, 

 fulvous hair; venter dark reddish, the segments fringed with fulvous 

 hair. 



Miarinarivo, (Queensl. Mus. 17). A beautiful species, nearest 

 to P. heydenii Sauss., but differing by the lack of fulvous hair on 

 first abdominal segment. It is also appreciably smaller, although 

 it is a female and heydenii was described from a male. It is named 

 after the author of the great work on Madagascar, in which Saussure 

 described several species of the same genus. 



Crocisa subcontinua Saussure. 



Miarinarivo, (Queensl. Mus. 49). — I have also a specimen 

 collected in Madagascar by Hildebrandt. 



Anthophora antimena Saussure. 



Miarinarivo, (Queensl. Mus. 47). — The specimen, a female, 

 is so grey in tone as to appear almost greenish, and the wings are 

 dusky. Possibly it represents a distinct race, but more material 

 is desirable. 



Megachile piliceps Saussure. 



Miarinarivo, (Queensl. Mus. 51). — This species (male) is 

 superficially almost exactly like M. perbrevis Cress., from Texas.
