1. PAKTTRGUS. 107 



Male. Length 3-4 lines. — Very closely resembling the female, bu^ 

 having the head larger than the thorax, sometimes half as wide 

 again ; the flagellum, except two or three of the basal joints, pale 

 rufo-testaceous ; the posterior femora have an obtuse tooth towards 

 their base beneath ; the posterior tibiae clavate, bent inwards ; the 

 tibiae and tarsi have a scattered pale fulvous pubescence ; the cal- 

 caria and apical joint of tbe tarsi pale ferruginous. B.M. 



This species appears towards the end of June or the beginning of 

 July, is much more local than P. banksianus, and frequents the 

 mouse-ear hawk weed (Ilicracinm). It has occurred at Blackheath 

 and at Darenth ; it is plentiful on the cliffs at Bournemouth, also at 

 Bonchurch and Luccomb Chine, Isle of Wight ; at Budleigh -Salterton, 

 South Devon ; and at the Land's End, in Whitesand Bay. At night 

 males may be found enclosed in the petals of the hawkweed near 

 the colonies, usually three or four in a single flower ; the females 

 pass the night in their burrows : very large-headed males may be 

 occasionally found. 



2. Panurgus dentipes. 

 P. ater, nitidus, glabriusculus, pedibus posticis fulvo hirsutissimis.

Female. Length 3| lines. — Black and shining ; the pubescence on 

 the head and thorax black ; the antennae black ; the legs nigro- 

 piceous ; the apical joints of the tarsi rufo-piceous ; the pubes- 

 cence on the tibiae and tarsi thin and fulvous, that on the posterior 

 pair long, dense, and fulvous ; wings hyaline, their nervures fuscous. 

 Abdomen ovate, margins of the segments depressed, with the apical 

 fimbria fuscous. 



Male. — This sex closely resembles the same sex of P. cdlcaratus, but 

 has black antennae and a blunt spine on the posterior trochanters. 



B.M. 



Having found this species mixed with P. calcaraius in the British 

 collection, I feel obliged to include it among our indigenous bees ; 

 future investigation must decide its right to a place in the list. The 

 locality (Salisbury) may be the means of establishing it when that 

 place and neighbourhood are carefully searched. 



The female is described from a continental specimen.
