48 Dr. M. Burr — Notes on the Forficularia. 



Size small ; general colour dark cheslnut, varied with 

 fulvous; shining; not very pubescent. 



Atiteinue greyish brov/n, with 14-15 segments^ cylindrical, 

 fourth a little shorter than the third. 



Head broad, smooth, sutures obsolete, tumid, dark chestnut- 

 brown. 



Pronotum a little broader than long, very slightly broader 

 posteriorly than anteriorly, alike in macropterous and brachy- 

 pterous forms, deep chestnut-brown, paler at tiie sides, which 

 are gently convex, as also the anterior margin ; posterior 

 margin truncate. 



Elytra ample, smooth, dark chestnut-brown, with a promi- 

 nent orange spot in the anterior portion, which sometimes 

 occupies the whole of the disc and is sometimes nearly 

 obsolete. 



Wings black, sometimes well developed, sometimes abbre- 

 viated. 



Legs yellow. 



Abdomen rather broad, subparallel-sided, deep red, very 

 finely punctulate, almost smooth- 

 Last dorsal segment J" transverse, smooth, truncate poste- 

 riorly, feebly depressed in the middle ; inflated at each angle 

 to a tubercle, which is sometimes merely tumid, sometimes 

 developed into a mammteform tubercle : in the ? simple. 



Penultimate ventral segment S ? ample, broad, very 

 gently rounded posteriorly. 



Pygidium c? very short, not protruding, broad, posterior 

 margin sinuate ; ? hidden. 



Branches of the forceps remote ; strong, trigonal, and 

 dilated at the base itself, then abruptly attenuate, bent down- 

 wards, somewhat bowed, and arcuate, to meet at a small 

 nearly obsolete tooth just before the apex: in ? simple, 

 contiguous. 



Western Abyssinia : Kuhne, in the mountains, on the road 

 from Harrar to Adis Abba, many specimens [G. Kristensen). 



This species is closely allied to the West-African S. tnber- 

 culataj Borelli, and H. rubra, Borelli ; the coloration is 

 diiferent, and the forceps, though of the same general type, 

 are different in detail. In these species the last dorsal 

 segment is furnished at each angle with a very prominent, 

 sharp, stout, conical tubercle, quite different from the some- 

 times mammteform tumid elevation of S. kristenseni. 



Mr. Kristensen sent me a good number of specimens ; the 

 commonest form is brachypterous, with the elytra almost 

 entirely orange-yellow on the disc ; a few males are macro- 

 pterous, and they have the yellow spot much feebler, smaller.
