NOTES ON TENTHREDINID2E. 

 " BY P. CAMERON. 



{Continued from vol. xvii, p. 67). 



Tenthredo scotica, sp. n. 

 Black ; clypeus, labrum, a line round the lower part of the eyes, one on the 

 pronotum, two spots over the posterior coxse, apical three-fourths of the under-side 

 of the front coxse, and an irregular spot on the apex of the two hinder ones, white. 

 Legs pale yellow, except the greater part of the coxae, which is black, and the ex- 

 treme apex of the posterior tibiae and the tarsi, which are dull fuscous. Wings 

 almost hyaline, costa dull reddish, stigma black. ? . Length, 5f lines. 



Similar to T. disbar in size and form, but having (apparently) the 

 antennae and metatarsi shorter, the head more opaque and punctured, 

 and differing otherwise in the coloration of the legs and face ; the 

 saw also differs. 



Rare. Taken near Dumfries, in June. 



THE BRITISH GREEN SPECIES OF NEMATUS. 

 With the valuable assistance of Mr. J. E. Fletcher, I have sub- 

 jected our green species of Nematus to a revision, and have satisfied 

 myself that we possess seven, if not eight, species. These are : 



1. N. JBergmanni, Dbm , sec. Thorns., = prasinus, Htg. 



2. iV! glutinoscB, sp. n. 

 G-reen, or testaceous-green ; the 6pace enclosing the ocelli, the usual marks 



on mesonotum (as in miliaris), a ring surrounding the cenchri, a small one behind 

 them, and a row of transverse marks on back of abdomen (becoming narrower to- 

 wards the apex), black. Antennae somewhat shorter than the body, filiform, black, 

 fuscous beneath, the 3rd joint a little longer than 4th ; the head bulges out dis- 

 tinctly behind the eyes ; looked at from above, the front projects sharply from the 

 surrounding parts, and is furrowed between the antennae. The frontal (pentagonal) 

 area is well defined and square at the apex ; the antennal fovea is indistinct, but a 

 well-marked furrow comes down on either side of it from the outer side of the 

 frontal area, and curves round the base of the antennae. The central furrow on 

 vertex is well defined, broad in front, narrow behind. Spurs a little more than one- 

 fourth of the length of the metatarsus, being as long as the cerci. Stigma greenish- 

 white. 



The S has the antennae longer than the body, with the 3rd joint shorter than 

 the 4th ; the lower part of the body and the sides of the abdomen above are 

 rufescent ; the upper part black, the thorax entirely so, save an incomplete ring on 

 scutellum, the central part of which is black. The hinder tarsi are fuscous-black ; 

 the stigma fuscous. Length, 1\ — 3 lines. 



Very similar to miliaris, ¥z., = viridis, Htg.,= microcercus, Thorns., 

 but the front is wider between the antennae, and does not project so
