Type in the Paris Museum. 



This is one of the largest species of the genus ; it is distin- 

 guished by its size, fuscous colour, and the form of the penultimate 

 ventral segment of the male. 



In a larva, the length of tiie basal segment of the cerci was 

 2-5 mm. ; the whole cercus 13 mm., composed of 15 segments ; 

 the body measured 10-5 mm.

G-eneral colour dark greyish brown, not very pubescent. 

 Antennae with 16 segments ^ greyish brown. Head dark reddish 

 brown, not very tumid between the eyes, this part passing 

 o-radually into the depressed occiput, as the transverse suture is 

 not very distinct ; median suture very short, with a few faint 

 blunt short ridges on each side ; postocular ridges sharp, about as 

 long as the diameter of the eyes. Pronotum a trifle longer than 

 broad, broad anteriorly, narrow posteriorly, the sides straight and 

 posterior margin truncate ; median suture distinct ; prozona 

 tumid and occupying greater part of the area ; metazona flat, 

 very short, sides flattened and somewhat reflexed ; dark greyish 

 brown. Scutellum very small. Elytra long and broad, smooth, 

 reddish-brown, convex at the posterior margin. Wings long and of 

 the same colour (membranous part clearly hyahne). Legs with the 

 femora fuscous, the carinulse obsolete, just perceptible on the pos- 

 terior pair ; tibise and tarsi very slender, pale and typical. Abdomen 

 browii, with a bronze sheen ; gradually increasing in girth towards 

 the apex ; last dorsal segment large, scarcely broader than the 

 abdomen, tumid, smooth, quadrate, the median sulcus faint; postero- 

 external angles rectangular. Penultimate ventral segment ample, 

 quadrate, posterior margin slightly emarginate, with a short 



1 Owing to the fragility of these organs, it is difficult to be certain what is 

 the normal number of segments even in living specimens : the antennae often 

 differ in this respect in the same individual. Green has counted as many as 17 

 and as few as 13 segments ; probablj 16 is the normal number.
