ABNORMAL COLEOPTERA. 457 



With regard to the number of British species of Stylops at present 

 known there is considerable doubt ; the type of the genus is regarded as 

 Stylops melittce, Kirby ; Westwood figures a species (Classification, 

 Frontispiece, fig. 6) as Stylops Spencii, Pck. ; while Curtis (Brit. Ent., 

 fig. 225) describes and figures a species as Stylops Dalii, Curt. ; Mr. C. 

 W. Dale (History of Glanvilles Wootton, p. 117) mentions two species 

 with their localities as follows : 



1. Stylops Dalii, Curt. Vciy rare. Taken by my father, flying over the gardtn 

 hedge, May 3rd and 23rd, 1S27, and May 10th, 1829. The females are only to be 

 found inside the tails of Andrena labialis. 



2. S. Kirlii, Leach, rare. Taken by my father, Mny 7th, 1827, May, 10th, 12th, 

 mid 14th, 1828, May 9th, 10th and 23rd, 1829, May 12th, 1836, and May 12th, 1840. 

 The females are only to be found inside the tails of Andrena barlilalris. 



The figure of S. Dalii given by Curtis (fig. 226) differs from that of 

 S. Spencii given by Westwood (Classification, Frontispiece, fig. 6) in 

 having the wings considerably more narrowed behind, the base of the 

 antennae shorte.r, and the post-scutellnm more produced over the abdo- 

 men, but these differences may be more or less accidental ; in a com- 

 munication I received from Professor Westwood (March 29th, 1889) he 

 says : " As to the species of Stylops, I believe there has never been an 

 opportunity of comparing the type specimens, so you must rely on your 

 own judgment, founded upon the only materials which now exist for 

 identification," and he further refers to one of the existing figures as 

 probably not very accurate ; under the circumstances I prefer to consider 

 that we have only one British species. 



S. melittae, Kirby (? .Dalii, Curt., Spencii, Pck., Kirlii, Leach). 

 Male of a deep velvety black colour, with the base of the scutellum and 

 the sides of the abdomen yellowish or yellowish-brown ; legs and pseud- 

 elytra fuscous ; wings ample, milky white and iridescent, with the sides 

 comparatively straight and produced in front into a broad blunt rounded 

 angle, nervures rather well marked, black or blackish, anterior edge dark 

 and thickened; female larviform. L. 3 mm. 



Parasitic on species of Andrena, ; male rare ; female not uncommon in some districts ; 

 the male flies with an undulatory motion very early on hot summer mornings ; London 

 district, Ueigate and Shirley (Champion) ; Woking (E. Saunders) ; bred from 

 Andrence taken at Hammersmith (S. Stevens) ; near London (Enock) ; Hastings; 

 Glanvilles Woottou ; Oxfordshire ; it probably occurs in many other localities. 



ELENCHUS. Curtis. 



This species differs from Stylops in having the antennce in the male 

 much longer and five-jointed ; they are inserted in a cavity on each side 

 of the front of the head and are slender and pubescent, with the first 

 and second joints short and the third produced on the side and forming 

 a long lanceolate appendage ; the eyes are almost sessile and composed of 

 only about twenty lenses ; the pseudelytra are clavate and longer than in 

 Stylops; the postscutellum is scarcely produced over the abdomen which is
