NEMATUS ASTUTUS. 77 



would seem to be a broader and stouter insect than 

 breadalbanensis, and the posterior tarsi are of a blacker 

 testaceous, the band on pronotum is broader, and the 

 apical segments of abdomen broad and dirty testa- 

 ceous. 



Breadalbanensis would appear to be an Alpine 

 species. I captured it on a mountain in Rannoch in 

 June, at an elevation of about 3000 feet. Near where 

 it was captured I found in moss a good many 

 cocoons of a Nematus presumably of this species. 

 Similar cocoons I have seen in like situations and at 

 the same altitude on many of our Scotch mountains. 

 I discovered both sexes in numbers on Ben More, Mull.

Nematus carinatus, Htg., Blattw., 199, 28; Kalt., Pfl., 700; 



Andre, Species, 1, 148, 147. ? 



Black, thick ; head as broad as the thorax ; antennae thick, as long as 

 the abdomen, the third and fourth joints about equal, the apical 

 joints thinner; labrum white, mandibles piceous, palpi dirty white; 

 apex of abdomen, cerci, tegulte, and a thin line on pronotum close to 

 te guise brownish-testaceous. Wings hyaline, costa and stigma yellowish- 

 white, iiervures pale at base of wing, darker at apex. Legs black, 

 apical half of anterior femora, the knees of posterior tibiae and tarsi, 

 brownish-testaceous, apex of posterior tibiae and tarsi fuscous black ; 

 the extreme apex of coxae and trochanters on underside testaceous. 

 Cerci as long as second joint of posterior tarsi ; sheath pilose, 

 projecting.

I formerly considered the species above described as 

 the ? of N. pallipes, but I now think it must be distinct. 

 It is much broader, the head is much thicker, the 

 clypeus black, cenchri larger, while the coloration of 

 the legs is darker, and the clypeus is not so sharply 

 truncated at the apex. The furrow on the middle lobe 

 of the mesonotum is very deep, and there is a raised 

 ridge running down the centre of the scutellum, which 

 is not visible in pallipes. In the latter, also, there is a 

 transverse furrow running across the apical third and
