536 Mr. P. Cameron's descriptions of ten new 



line, bordered on either side by a narrower white one. 

 On the side runs another white line ; all the lines end on 

 the 2nd last segment, which with the last is of a lighter 

 green colour, and bear a broad white mark on the top. 

 The skin is beset with numerous little black points. 



Nematus glottianus, n. s. 



Dark reddish-luteous ; the hinder edge of vertex and a 

 longitudinal line on each of the lateral lobes of the 

 mesonotum black. Antennae pale testaceous, not much 

 longer than the abdomen ; metathorax stout, attenuated 

 at the apex ; the 3rd and 4th joints equal ; the apical 

 joints are slightly fuscous ; mesonotum finely punctured. 

 Wings yellowish hyaline ; stigma and costa testaceous ; 

 3rd cubital cellule one-fourth longer than broad. Tarsi 

 nearl}^ as long as the tibi^, extreme apex of all the 

 joints fuscous ; metatarsus not double the length of the 

 2nd joints ; spurs one-third of the length of the meta- 

 tarsus. Length, 3 lines. 



The larvae feed gregariously on the leaves of Salix 

 cinerea in the autumn. The head is a little narrower 

 than the 2nd segment, is intensely black and slightly 

 punctured ; the sides of the mouth are greenish. Legs 

 glassy white, slightly tinged with green ; claws black ; 

 claspers light green. The body is of a beautiful dark 

 sea-green. On the sides are ten large oval orange spots, 

 divided by a fold of the skin in two, but still remaining 

 continuous. Below there is a line of roundish, irregular 

 black dots, and below these again and over each clasper 

 is • a longish, oblong, black sjjot ; while there are two 

 rows of small black dots, these, however, forming the 

 commencement of the middle line of black dots. Over 

 the orange marks is a line of close continuous black 

 dots, irregular in shape, but, if anything, pblong, and 

 which proceed from the 2nd to the 12th segment. On 

 the back are, at the termination of each segment, two 

 rather small roundish dots. Directly over the anal 

 • segment is a large round black mark, much larg^- than 

 any of the others. The first orange spot is directij over 

 the 2"nd pair of legs. Length about 1:|- inch. 



The cocoon is of the usual form and colour, is double, 

 and is spun in the earth. 



Seemingly a rare species. I have only met with the 

 larvae once in the autumn near Port Glasgow.
