Stylops. ] 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 melitte, 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. sie, 
W. Dale (History of Glanvilles Wootton, p. 117) mentions two species 
with their localities as follows : 
1, Stylops Dalii, Curt. Vey rare. Taken by my father, flying over the garden 
hedge, May 8rd and 23rd, 1827, and May 10th, 1829. The females are only to be 
found inside the tails of Andrena labialis. 
2. S. Kirbii, Leach, rare. Taken by my father, May 7th, 1827, May, 10th, 12th, 
and 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 barbilabris. 
The figure of S. Dalit given by Curtis (fig. 226) differs from that of 
S. Spencti given by Westwood (Classification, Frontispiece, fig, 6) in 
having the wings considerably more narrowed behind, the base of the 
antenne shorter, and the post-scutellum 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. melitte, Kirby (? Dalit, Cut., Spencii, Pck., Kirbii, 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, Reigate and Shirley (Champion) ; Woking (E. Saunders); bred from 
Andrene taken at Hammersmith (S. Stevens); near London (Enock) ; Hastings; 
Glanvilles Wootton ; Oxfordshire ; it probably occurs in many other localities. 
ELENCHUS, Cutis. 
This species differs from Stylops in having the antenne 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 eyesare 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
