 This appears to be a rare species. I have onlj seen one specimen, which I 

 captured some years ago upon Shirley Heath. It is characterized by having the 

 palpi yellow with black tips, as in P. nigritarsis, Zett., which species it a good deal 

 resembles, but from which it differs by having the shoulders and scutellum yellow, 

 and the abdominal segments of the female marked by transverse black lines. 



P. HYOSCYAMI, Panz. 



I bred two females of this species from larva; which liad mined, or rather 

 blotched, the leaves of garden beet in August, 1886. This shows that phytophagous 

 insects do not always confine themselves very closely to plants of the same family.

P. EPHiPPiUM, Zett., Schm. 



In July last (1887), after the last part of this Supplement had 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. The 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 

 towards 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 P. vittigera. 



I do not know tho female.
