each side of the body as far as the commencement of the fourth abdominal 

 segment where it becomes somewhat interrupted; the interval between 

 this line and the margins of the dorsal arcs of the body is silvery white ; 

 below, the insect is of an uniform light yellowish green ; above, between the 

 brown lateral lines, darker green ; the meso- and meta-notum are indistinctly 

 carinate down the middle, and under a moderately powerful lens appear to 

 be marked with delicate wavy transverse striae ; the striation becomes less 

 distinct on the abdominal segments. The abdomen is slightly expanded 

 at the junction of its 4th and 5th segments from which latter it sensibly 

 decreases in width to the apex of the seventh, whence it widens to a trifling 

 extent ; seventh segment equal to about 1^ times the 8th, exactly twice 

 as long as the 9th which is obtusely rounded at the extremity and above 

 presents a median and two lateral less distinct ridges ; these latter curve 

 inwards at their apical ends, enclosing a shield-shaped area. Posterior 

 margin of the terminal ventral segment slightly emarginate. 



Legs simple, of excessive tenuity ; anterior very slightly longer than 

 the posterior pair ; intermediate shorter by the length of their own tibia 

 than the former. Cerci long, obtuse, porrected beyond the apex of the ab- 

 domen, slightly forcipated and grooved at the sides. 



Total length 22 lines ; head 1^, prothorax 1, mesothorax 4|-, meta- 

 thorax 3|, abdomen d\ -f- 2\ = llf ; antennae 3i.

$ Filiform, slender, sordid, with a dark-green median dorsal streak, 

 extending from the apex of the mesothorax to the extremity of the abdomen. 

 Head sub-ovate, with the sides slightly convergent posteriorly, antennae 16- 

 jointed, joints very distinct ; first joint depressed but not expanded ; second 

 twice as long as broad, cylindrical, its proximal end the broader. Mesothorax 

 hardly narrower in front than behind. Meso- and meta-notum with a 

 raised median line and a few minute tubercles on their lateral margins. 

 Abdomen cylindrical and filiform to the apex of the 6th segment, whence 

 it suddenly expands to the junction of the 7th and 8th, whence it narrows to 

 its truncate extremity which appears to be constricted between the 8th and 

 9th segments ; six basal segments slightly expanded at their articular ends ; 

 9th segment strongly carinate ; the cerci curved and projecting at its postero- 

 lateral angles. 



Legs long, slender, and simple ; first joint of anterior tarsi greatly 

 ehmgated ; rather more than twice as long as the remaining joints taken 

 together. 



Total length 241 lines, antennae 4, head 1|, proth. 1, mesoth. 5^-, 

 metath. 4i, abd. 10\ -f 2i = 12^ lines.
