The apical half of the mandibles is mainly red, and the 
slender teeth at sides of base of sixth abdominal segment are 
red. It therefore seems evident that taurus is at least a valid 
subspecies. ‘True polycentris gets as far east as the Caucasus. 
I have not seen the female of taurus, but from Nurse’s 
description it would seem that the apical ventral plate is not 
nearly so long as in polycentris. 
Paracelioxys rufiventris nurset, subsp. n. 
? .—Mandibles bright ferruginous, black at apex; legs 
red; abdomen entirely red, truncate and emarginate at 
apex ; vertex thinly hairy. 
Length about 10 mm. 
Deesa, India, March 1900 (Nurse). 
Friese labelled this rufiventris, Spin., but the typical ruj- 
ventris, from Egypt, is larger and has black legs. ‘The male 
of nurset is not known, but it probably has a black abdomen, 
as in rufiventris. 
Paracelioxys resembles Liothyrapis in having bare eyes, 
but the structure of the abdomen is quite different. The 
genus is new to India. 
All the new Indian bees described above are represented in 
the Nurse collection at the British Museum. 
Megachile diodontura, sp, n. 
g.—Length about 7°5 mm., anterior wing 7 mm. 
Black, with head almost as large as thorax and short broad 
abdomen; mandibles black; antennal joints 4 to 10 chestnut- 
red beneath, the apical part of 10 blackened ; clypeus exposed, 
convex, shining, with scattered strong punctures; long black 
hair at sides of clypeus and below antennee, but hair of face 
and front mainly cream-colour, with a long beard from lower 
margin of clypeus; vertex with short, thin, pale hair, and 
some longer hairs interspersed ; a band of dark hairs across 
front just above antennee ; vertex dull, very finely rugoso- 
punctate, the former with a short smooth line on each side ; 
hair of mesothorax short, thin, pale yellowish, the hind 
margin (scutello-mesothoracic suture) with a narrow but very 
distinct pale band; scutellum with stiff black hair; pleura 
with dull white hair; tegule ferruginous. Wings dilute 
orange, with clear ferruginous stigma and nervures, but 
apically broadly infuscated. Legs very dark reddish, nearly 
black, with short pale hair; anterior tarsi simple; anterior
