surface 1)ct\vcru tlio i)uncturos shining ; tliorax above with 

 very thin and short jjalc oclircous hair, and no distinct 

 sutural bands : area of nietathorax granular at base and 

 sides ; teguhe rulo-piceous. Wings hyaline, dusky apically, 

 stigma large, dark ferruginous. Legs with short pale hair. 

 Abdomen finely and closely punctured, the bases of the 

 segments deeply impressed ; first segment with lateral pale 

 apical hair-patches, third and fourth with conspicuous basal 

 bands of glittering scale-like pubescence, fifth with the basal 

 lialf thinly covered with pale hair, aud sixth with even more, 

 the hair pale ochreous-tiutcd and glittering; hind margins 

 of second aud following segments very narrowly fuscous; 

 sixth segment vertical, the keel feeble, not or harely de- 

 pressed in middle, a short tooth on each side of apical 

 margin of segment. 



Hub. Cuernos Mts., Negros, Philippine Is. {Baker, 31-17, 

 = type) ; Dapitan, Mindanao [Baker, 3139). 



This minute species recalls some of the Australian forms, 

 but does not resemble them in detail. I do not know^ any 

 near relative. The small size and red tarsi readily dis- 

 tinguish it in the Philippine fauna. 



Megachile indianorum, Cockerell, variety a. 



A male from Jacksonville, Texas, at Helenium tenuifoUum, 

 Aug. 11, 1906 (Bishopp), represents a new variety with 

 black legs. It differs in the pubescence and the colour of 

 legs from Cressou's description of M. dejiexa, but it is not 

 improbable that both this insect and true indianonaa repre- 

 sent varieties or races of dejlexa. It also seems jjossiblo 

 that M. megayyna, Cockerell, is the female of tlie present 

 variety, although it has darker wings, and the strong coarse 

 sculj)ture of the clypeus is entirely different. A female 

 M. megagyna was taken at Ardmore, Okla, July 11 (Jones). 



Megachile arnica, Cresson. 



The male closely resembles that of M. integra, Cresson, 

 but is certainly distinct, being smaller, with no band in the 

 suture between scutellum and metatliorax, while tlie apex of 

 the abdomen beneath presents a sharj) median spine, wanting 

 in Integra. The curious claviform hairs beneath the white 

 fringe on anterior tarsus are characteristic. The species, 

 liowevcr, appears to be remarkably variable. One from 

 Cotulla, Texas, on Verbesina encelioides, April 27, 1906 

 (F. C. Pratt)., is scarcelv 85 mm. long, and has the hair of
