104 NEMATUS TUEGIDTJS. 



breast smooth and shining. Mesonotum with three black spots of a 

 variable size, sometimes wide apart, sometimes almost continuous; 

 scutellum luteous, the metanotum also luteous, but sometimes marked 

 with black. Breast black, and there is a black line below the wings ; 

 the post-sternum is also black ; the cenchri are large, white. Abdomen 

 a little longer than the head and thorax, cylindrical, tapering at the 

 apex ; the last segment thin, leaf-like, arching over the saw ; luteous, 

 sometimes marked with black transverse spots ; the cerci are longish, 

 thin, darkest at the apex, the sheath black; the saws very broad. 

 Legs pale luteous, the coxse faintly marked with black ; the tibiae 

 whitish ; apex of tarsi fuscous ; the anterior tarsi are shorter than the 

 tibia3 ; calcari short. Wings almost hyaline, but with a faint smoky 

 tinge; the costa and stigma pale yellow, nervures blackish, except at 

 the base, where they are faintly yellowish. The first transverse cubital 

 nervure is very faint; the second cellule is more than double the 

 length of first, and angled where it receives the recurrent nervures ; 

 the second recurrent nervure is received a little in front of second 

 transverse cubital. 

 Length 3% lines. 



This species is not difficult to separate from the 

 other species of the group through the light reddish 

 colour of the body and legs, the amount of black on 

 it being very little. The abdomen and legs are some- 

 times without any black, while the thoracic marks as 

 well as that on the vertex are often very small, and 

 the mark on the breast is divided in the middle. 

 With the darker coloured aberration the femora are 

 lined with black at the base. The ^ is unknown. 



Brischke bred it from a larva which he found in 

 the earth on June 28th preparing to pupate, having 

 already moulted. It was smooth, wrinkled, with 

 padded sidefolds, and of a uniform carmine-red colour, 

 the eyes and mouth only being blackish-brown. The 

 imago appeared on August 4th. 



Turgidus seems to be rather rare. I have only 

 seen two specimens taken at Glanville's Wootton by 

 Mr. Dale, and two or three taken by myself in 

 Clydesdale. 



It is also rare in Prussia and Sweden. 



Obs. There can, I think, be no doubt that the pallicercus of Hartig 

 is a variety of capreae ; and I think also that the pallicercus of 

 Thomson is the present species, although his description does not 

 agree in some slight particulars with the specimens I have seen, but 

 considering how variable the species is these slight discrepancies can 

 scarcely be regarded as of very great importance. The pallicercus of
