GENUS TENTHREDOPSIS. 151 



line is a smaller darker stripe. Head shining, shortly 

 haired; eye-spots black; antennas and mandibles 

 brown. At the last moult it becomes shining, grass- 

 green. 



It is not very clear what this (brevispina, Brischke) 

 species may be. Brischke says that not only did he 

 breed T. brevispina from these larvsD, but also P. tilise, 

 Pz., and a $ of P. nassata ; the latter being the 

 nassata of Thorns. = cor data. 



He further describes (1. c, 107, pi. vii, fig. 6) the 

 larva of T. scutellaris, Pz., as a feeder on Anthriscus 

 sylvestris, Artemisia eampestris, and on grasses in 

 September and October. It is 15 mm. long, becoming 

 attenuate posteriorly, transversely wrinkled, with a 

 comparatively large head. The ground colour is 

 greyish- white. On the back is a brown central line ; 

 on each side of this is a line of light brown spots, 

 then a line of smaller brown spots, followed by a clearly 

 separated, broader, deep brown lateral stripe; on which, 

 on segments 3 — 4, are white warts arranged obliquely. 

 Over the feet is a brown mark. Stigmas brown. 

 The anal segment bears about five hairs, and has only 

 the middle and the broad lateral stripe. Head shining, 

 shortly haired, light brown, and bears the dorsal, 

 the narrow, and the broad lateral body stripes. In 

 front there are five lines converging to the centre, 

 the oral region having a triangular line. Mandibles 

 and claws brown. At the last moult it is shining 

 without warts, with the dorsal stripe lighter and 

 narrower, and the head without the dark markings. 



Brischke says that sometimes the larvsG have green 

 instead of brown markings. 



Our species, on Konow's views, will now stand 

 thus: 



1. (2) Antennae longer than the abdomen ; spurs reaching to the 



middle of the abdomen ; hypopygium very long. 



T. cor data, Fourc. 



2. (1) Antennae not longer than the abdomen ; spurs not reaching to 



the middle of the metatarsus ; hypopygium moderate or 

 small.
