182 [July, 



rather smaller than the others, has, above, a partially hardened plate, with a row ot 

 strong hairs arranged nearly in a semicircle ; it also bears the anal limbs, which are 

 short and strong, with a large blunt simple claw ; the claw has a number of strong 

 hairs, as have also the contiguous parts of the anal limbs (while these limbs are 

 probably two-jointed, the second joint appears to me to be little more than the claw). 

 The branchial tracheae are strongly developed, and occur in dense fascicles on the 

 anterior part of each segment from 2nd to 8th inclusive on the latero-dorsal and 

 latero-veutral surfaces ; the Ist segment has in addition two latero-ventral fascicles, 

 and the 2nd and 3rd segments a fascicle on either side in a line with the lateral 

 fringe. These fascicles, as far as I can make out, are not composed of simple fila- 

 ments, but consist of two or three main trunks, whence arise branches, which in 

 turn break up into minor subdivisions. 



Colours : greenish ; head almost white on the vertex, with a dark brown or 

 fuscous a;-shaped marking on the clypeus ; two lines, composed of fuscous dots or 

 clouds, converging posteriorly. Pronotum yellowish, with darker nebulae, and mar- 

 gined behind with black. Blesonotal plate yellowish, with light fuscous bands 

 running lengthwise and transversely, and a few small darker dots ; also margined 

 behind with black. Metanotal plates pale fuscous, with a few darker dots at either 

 end ; posterior plate dark in the middle. Legs yellowish, basal parts with black 

 lines and black dots on the proximal ends of the joints. The anal claws are also 

 yellowish, with black lines on the adjoining hard parts. Abdomen purple-grey 

 above, green beneath, respiratory filaments pinkish. 



Nympli cylindrical, stout (especially in the ?). Head transverse; inter- 

 antennal sulcus (so conspicuous in the perfect insect) distinctly marked. Antennae 

 long (as is usual in the longicorn LeptoceridcB), apical portion wound round the 

 posterior end of abdomen. Fore part of labrum transverse ; base broader and 

 sloping, with three hairs or so on either side ; a number of hairs at fore-angles and 

 on the disc ; anterior margin beset with a close row of points. Mandibles with a 

 sti'ong basal part, which passes into a flat blade-like sharply dentate part, ending in 

 a hook ; seen from the side only the broad base with a long slender hooked process 

 is visible. Maxillary palpi incurved ; the two basal joints short, of about equal 

 length ; the three other joints become gradually more slender. Labial palpi with 

 first two joints short, third longer. 



Thorax robust, the round scutelium of mesonotum distinct in nymphs nearly 

 mature. Wing-cases long, the pointed apices reaching fith abdominal segment. 

 Tarsi of anterior legs sparingly, and those of median legs strongly, fringed on their 

 inner side. Tibiae and tarsi externally with minute blunt points at the joints. 



Abdomen stout, after 7th segment becoming narrower. The 3rd to 7th seg- 

 ments inclusive have each anteriorly two dorsal plates, which bear a single, strong, 

 backward directed, flattened, blunt tooth ; 5th segment posteriorly with two trans- 

 verse and more closely approximated plates, each with three hooks directed forwards, 

 one hook being placed at each hind angle and the other between (the last is smaller 

 than the other two hooks, and may only occur in the $). Branchial trachse in 

 •dense tufts on the anterior part of each segment, from 2nd to 7th inclusive, on the 

 pleura;, one tuft above and the other below the lateral line, and on tlie 2nd and 3rd 

 segments an additional tuft placed intermediately. Lateral fringe short, just indi- 

 cated on 6th segment, strong on 7th and 8th, passing to the ventral surface of the
