234 [September, 



(under) edge of the Ist pair being regularly ciliated ; tlie other joints barer; the 

 few hairs on tibiae and tarsi of 2nd and 3rd pairs mostly of very great length. The 

 inner side of fore-legs armed with a number of spines, of which there are also a few 

 on tibise and tarsi of 2ud pair ; there is also a row of minute spines on the inner 

 side of femora of 2nd and 3rd pairs. 



First abdominal segment broadest of all, the usual processes (dorsal and lateral) 

 well developed ; from it the body gradually tapers to the anal extremity, the 9th 

 segment being rather conspicuously smaller than the others. No lateral fringe of 

 the ordinary character ; it is represented on segments three to eight inclusive by a 

 row of minute hairs, a slight modification occurring on the anterior part of 8th 

 segment, where, instead of hairs, there are small, closely set, bifid processes. The 

 anal limbs are rather long ; proximal joint large, the smaller distal joint bears the 

 claw, which has two hooks, a large and a small one, the latter being bifid ; both joints 

 carry some extremely long hairs. 



Brandiial tracheae occur on abdominal segments one to seven, placed anteriorly 

 on the latero-dorsal and latero-ventral surfaces, segments one and two having them 

 also on the lateral surfaces. In the posterior segments they take the form of single 

 filaments or groups of two, but the dorsal filaments of the first three segments are 

 strongly developed, and consist of a short and broad basal part carrying many (5 — 8) 

 filaments, which are turned inwards over the back, so that the filaments of one side 

 almost meet those of the other. 



Colours : pale green ; head above olivaceous-brown with two pale lines, which 

 converge posteriorly, forming a sort of U (these lines mark the outline of the 

 clypeus), the eyes placed on large pale patches ; pronotum beautifully marked with 

 thickly set, small, round, blackish or brown dots, which become larger and less 

 closely set in the posterior part ; mcsonotum greenish-fuscous, with darker points. 

 Legs clear yellowish, anal hooks yellowish. 



Nymph : very long and slender ; head transverse ; labrum much as in Beraa 

 maurus, but more rounded and hairs different (compare figs.) ; mandibles longer 

 and more slender than in Bercea. 



Middle pair of legs with tarsi provided with dense fringes of long silky hairs ; a 

 slight fringe also on tarsi of anterior pair. Wing-cases reaching end of 5th segment, 

 acute. 



Abdomen : 3rd to 6th segments inclusive with two anteriorly placed small oval 

 plates, each of which bears a backward-directed hook ; 5th segment with two pos- 

 terior transverse plates, each bearing two or three forward-directed hooks. Branchial 

 tracheffi on segments two to six at least ; they are placed on the pleura; on the an- 

 terior part of each segment ; two fa.^cicles on either side, one towards the dorsal and 

 the other towards the ventral surface. The appendages are long, upturned towards 

 the tip, which slightly before the extreme apex is notched beneath, and in the notch 

 is a short spine ; the appendages are covered with fine points, and each carries on its 

 upper surface three long hairs. 



The cases of S. miniita are not unlike those of B. maurus, but 

 are more slender ; length, 7 — 9 mm. The tail end is hardly truncate, 

 and consequently there is usually no distinct membrane visible. All
