In July last (1887), after the last part of this Supplement bad been sent to 

 press, I found three males of this species (which has not yet been recorded as 

 British) at Baslow, near Chatsworth in Derbyshire. It bears a close resemblance to 

 both P.fulgens and P. vittigera, but is decidedly distinct from either. The scales 

 of the alulets are rather small, but unequal in size ; therefore it must be placed in 

 my first division of the second section of this genus. 



The palpi are entirely yellow. The thorax is reddish-brown on the dorsum, 

 covered with grey tomentum, and having the shoulders and sides, as well as the 

 front edge, yellowish-white. The scutellum is yellow. Tlie halteres and alulets are 

 pale yellow. The abdomen is oblong, narrow and flat, brownish-yellow (testaceous) 

 in colour, somewhat paler and translucent at the base, and becoming nigrescent 

 t-owai'ds the end. It is hairy, and furnished beneath the apex with large, black, 

 globular genital appendages. The legs have the tarsi black, and there is also a black 

 patch (Wisch) on the upper surfaces of the ends of the femora ; all the rest of the 

 limbs is pale yellow. This species differs from P. fulgens by having the alulets 

 rather smaller, the palpi wholly yellow (without black tips), and the femora blackened 

 on their upper extremities. It may be known from P. vittigera by its having the 

 whole dorsum of the thorax grey, instead of its being only marked by a longitudinal 

 grey stripe ; and by the femora being blackened upon their upper ends, not sur- 

 rounded near their apices with a black ring as in /'. vittigera. 



I do not know the female. 



CAEICEA, E. Desv. 

 C. EXSUL, Zett., and Scbin.* 

 Both males and females of this fine species were sent to me last year by Miss 

 R. Prescott Decie, of Bockleton Court, Tenbury. She had captured them in Devon- 

 shire. The antennae and palpi are black. The arista is sub-plumose. The frontal 

 space is much narrower in the male than the female, being about one-fourth of the 

 width of the head in the former and more than a third in the latter sex. The face 

 is rather prominent, and of a silveiy-white colour, which extends up the sides of the 

 frontal space, the middle of which is occupied by a bluish-grey stripe. The thorax 

 and abdomen are clear ash-grey ; the former is marked by two narrow longitudinal 

 stripes placed near together, and has the shoulders and sides white. The abdomen 

 is oblong and sub-cylindrical in the male, ovate and pointed in the female ; it is 

 marked on the back by four reddish-brown spots ; the ai^ex in the male is but little 

 thickened, and the genitalia small. The legs are black, wilh the exception of the 

 four posterior tibiae in the male, which arc testaceous, as well as the front knees and 

 the points of the other femora. In the female the fore tibiae are also brown. The 

 tibiae are surrounded at their extremities by a gi'oup of strong spines as in C. tigrina. 



* Schiner sytlls tUe name of this species exul, but I think that Zetterstedt in correct.
