436 TABANID^ 



localities are known in Kerry, Cork, and Galvvay. The specimens from 

 Kenmare, Co. Kerry, have been noticed above in the remarks about the 

 variation of the species. My dates range from May 24 to August 26. 

 It is recorded from North and Central Europe. 



Synonymy. — Tahanus nuhilosns of Moses Harris (1782) is usually given as a 

 synonym of C. relicta, but his figure is uncertain and as he said "The legs are 

 " black " it may be taken that he had C. cceciitiens before him, and consequently no 

 question of priority can arise. C. melaiiojyleura Wahlb. is now believed to be a 

 variety of C. relicta in which the pubescence on the pleuree is all black. Pandelle's 

 ridiculous statement that C. ccecutiens, C. qtiadrata, and C. relicta are only varieties 

 of one species merely serves to show the superficiality of his work. 



4. C. sepulcralis Fabricius. Entirely black in both sexes. 

 The smallest British species of the genus, easily known by 

 the absence of orange markings about the base or basal 

 corners of the abdomen. 



$. Face and jowls almost entirely covered by the shining black calli, so that 

 only a narrow brownish orange middle line remains, though in good specimens 

 there may be a little grey dust on the sides of the face (between the facial 

 and buccal calli) extending rather broadly about half-way across the disc 

 of the face ; the ground colour of the face may be rather obscurely ferruginous 

 at the place where the grey dust commences near the eyemargins, and the 

 sides of the mouth may be obscurely dark ferruginous, and in fact in some 

 lights all the sides of the face may be broadly though obscurely dark 

 ferruginous from near the antenna to the sides of the mouth, leaving only 

 the spaces down the sides of the brownish orange middle line shining black ; 

 pubescence on all the head (face, jowls, vertex, and antennae) black or rusty 

 black ; back of the head slightly hollowed out behind the eyes right away 

 from jowls to top, and with a minute black postocular fringe ; vertex dull 

 black, elevated, and bearing rather dense long pubescence ; frons bare, shining 

 black, but dusted brownish orange all across just above the antennae, and this 

 dust extends all round the antennae so as to connect with the similar middle 

 line of the face. Proboscis long, black, and rather shining about the tip ; 

 palpi black, and bearing long pubescence. Eyes with the facets on about the 

 upper two-thirds larger than those on the lower part, but only contrasted in 

 a line across the middle of the disc (not near the front or back margin of the 

 eyes) ; in life the eyes are brilliant blue green with three purple spots and a 

 faint streak, two of the purple spots and the intermediate streak being on the 

 forepart of the eye, and the upper spot scarcely above the middle of the 

 eye and not close to the foremargin, while the third spot is a small one near 

 the hind part of the eye in a line with the streak. Antennae dull black but 

 the third joint rather brownish ; basal joint longer than the second, and both 

 bearing long and rather abundant black pubescence. 



Thorax and scutellum all black, only moderately shining and not at all 

 striped • pleune rather obscured by brownish dust. Pubescence all black or 

 rusty black, long, erect, and fairly abundant ; pleurae bearing rather dense 

 black pubescence even to the lower part. 



Abdomen all deep black and very little shining ; pubescence abundant and 

 all black, some of the erect hairs on the disc of the two or three basal 

 segments fairly longj even the ends of the genital lamellge dull black or 

 only slightly brownish. Belly black and very little shining, with the 

 pubescence rather less dense than on the dorsal side. 



Legs black, almost dull ; pubescence on the coxae and femora long and 

 black but not dense ; hind tibice thickened and bearing dense black 

 pubescence. 



_ Wings (fig. 240) mainly blackish, but with a small middle part and a large 

 apical part almost hyaline and with the hind angle (including the anal cell) 

 rather washed out; the middle hyaline part consisting of a space iiear the
