TAXnNTS FLETttHKKT. 205 



mandibles darker ; the black eyes are placed in the 

 pale-coloured part of the head. Legs glassy 

 white, with pale brown claws. The upper part of the 

 body to the spiracles is dark drab-green, which has a 

 lighter tint when the food canal is filled ; the lower 

 part is white ; the skin is closely wrinkled. When 

 full fed the colour of the body has a yellowish tinge. 



The pupa is glassy green, with the limbs white. 



The larvae bore into the stems of brambles and other 

 plants with pithy stems in order to pass the pupal state. 



A very common and universally distributed species. 



Its European distribution is the same as that of 

 jUguiseti. 



As already remarked (antea, p. 30), I succeeded in 

 getting virgin females of T. glabraius to lay eggs, and 

 I am now able to add (June, 1882) that three males 

 were reared from these unfertilized eggs. 



4. TAXONUS FLETCHEKI. 



Ta.tonus Fletcheri, Cameron, E. M. M., xiv, 266 (1878). 



Black, shining, covered with a scattered pubescence ; labrum, edge of 

 pronotum and tegulse white ; legs reddish, pale at the base, and at the 

 anterior tibia? in front ; apex of the tibia) and tarsi black. Wings 

 almost hyaline ; costa and stigma black ; the transverse radial nervure 

 is almost interstitial. . 



Length 2 lines. 



An easily recognised species. It is three-quarters of 

 a line shorter than the smallest male I have seen of 

 T. '/hilratiis, and its body wants the coppery hue of 

 the last-mentioned species, while it has also the tegulas 

 and edge of the pronotum white. 



The T. albipes of Thomson comes near to Fletcher*, 

 but it has the pronotum black, the body almost gla- 

 brous, legs yellowish- white, the four anterior tarsi and 

 apices of tibia3 are not black, while Albipes is likewise 

 larger than our insect. 



The only specimen known was taken by Mr. J. E. 

 Fletcher, of Worcester, near that place on 30th July 

 on alder.
