56 Psyche [April 



Hub. — Porto Velho, Rio Madeira, Brazil {Mann & Baker). 

 This little species resembles the Mexican M. bidentis Ckll., but 

 differs in the color of the wings, dark fuscous nervures, and some- 

 what larger head. They are however closely related. The color 

 of the nervures and tegulse w411 also separate M. microsoma from 

 the South American M. jpilosa Sm. 



Megachile permunda sp. nov. 



Male. Length about 9 mm.; black, the femora and tibiae a rather Hvely chest- 

 nut red, all the tarsi light yellow; a short compact species, superficially like the 

 Australian M. sequior Ckll.; eyes light green, the lower part tinged with red; man- 

 dibles and antennae black, the flagellum very faintly reddish below; face densely 

 covered with shining golden hair; lower part of cheeks, and under side of thorax, 

 with pure white hair; the broad vertex, and thorax above, with long erect dark 

 fuscous hairs, but mesothorax margined all round, and scutellum in front and behind, 

 with dense fulvous tomentum, the edge of the fulvous area in front of mesothorax 

 trilobed or tri dentate posteriorly; abdomen with entire pale fulvous apical hair- 

 bands, but band on fourth segment broadly interrupted, while fifth has no apical 

 band, but its basal third or more is densely covered with appressed fulvous hair; 

 sixth segment densely covered with creamy-white hair, except the projecting mar- 

 gin, which is broadly emarginate, but otherwise simple; ventral segments with white 

 hair-bands; apical antennal joint slightly broadened; mesothorax and scutellum 

 dull, densely granular; tegulse dull ferruginous; wings dusky; anterior coxae with 

 strong black spines; anterior tarsi hardly broadened, but with a long white fringe 

 behind, on the inner side of the fringe is some black hair; middle tarsi posteriorly 

 with extremely long white hair; hind tarsi with long white hairs in front; spurs 

 yellowish- white. 



Hab. — Natal, Brazil, two males (W. M. Mann). Except for 

 the almost simple anterior tarsi, this much resembles the Mexican 

 M. veraecrucis Ckll. 



Exomalopsis paraguayensis manni subsp. nov. 



Female. Length about 8 1 mm.; black, the mesothorax, scutellum and abdomen 

 shining; agrees with the description of E. paraguayensis Schrottky, except 

 as follows : mesothorax shining, not very densely punctured, the anterior third with 

 scanty pale hajr, the posterior part with very scanty black hair, easily overlooked; 

 scopa of hind legs creamy- white, the basitarsi densely black-haired behind; wings 

 dusky at apex; stigma large, amber-color, nervures more dusky; tegulae rufo- 

 piceous. The head is broader than long, and the abdomen is elongate, not sub- 

 globose as in many Exomalopsis. The base of the metathorax is roughened. The 

 mandibles are black, with a bright red spot about the middle. The b. n. goes 

 basad of t. m., and second s. m. is very small.
