Genera and Species of Longicorn Coleoptcra, 257 



linea media elevata plus minusve distincta ; eljtris fulvo tenuis- 



sime pubesceiitibus et sparse setosis. 

 Long. 27-31 tiiillim. 



Hah. Valley of the Tigris and Euplirates. 



Prothorax rather strongly and sonievvhat rugosely punc- 

 tured at the sides ; the disk sometimes rather smooth, espe- 

 cially posteriorly, and provided with a median, slightly elevated 

 line or carina, which in some examples is almost obsolete. 

 The elytra each bear one or two feeble or almost obsolete 

 longitudinal costse, and are furnished with small punctures 

 of two kinds : — 1st, the very minute pits from which the 

 short hairs of the pubescence arise, and, 2nd, the somewhat 

 larger and sparser pits from which the longer setae spring; they 

 are of a testaceous colour, somewhat darker towards the base. 

 The female of this species, which was taken at Fao, on the 

 Persian Gulf, has been presented to the Museum by Mr. W. D. 

 Cumming ; for the male, taken at Bussorah, I am indebted to 

 the liberality of Mr. R. Wylie Lloyd. A much damaged 

 specimen, which has long been in the Museum collection, was 

 brought from near the ruins of Nineveh. 



Niphona tibialis^ sp. n. 

 N. ciilindraceo' similis, sed prothorace lateraliter minus valde den- 

 tate, tibiis intermediis ( J ) versus apicem intus crassatis et valde 

 spinosis. 

 Long. 22 raillim. 



Hah. Canara, South India {Bell). 



Pubescence greyish, with a number of small scattered rust- 

 coloured spots. Prothorax rather darker than the rest of the 

 uppcrside, with two short feeble ridges running close together 

 along the middle of the disk, and, external to these, two or 

 three small tubercles on each side of the disk. There is a 

 rather small but distinct tooth low down on each side a little 

 behind the anterior margin of the prothorax, and a larger 

 blunter tooth or tubercle higher up and nearer to the middle. 

 The elytra are thickly and strongly punctured, though the 

 punctures are to some extent obscured by the close pubescence ; 

 each has at the base a few small tufts of dark brown hairs, 

 and, just below the shoulder, two very short dark brown 

 vittse ; a pubescence of a paler grey forms two somewhat 

 irregular and ill-delined bands crossing the elytra, one before, 

 the other behind, the middle. In the male the fifth abdominal 

 sternite has a peculiar form ; the posterior half is marked by 

 two grooves, which divide off two lateral poitions from a 

 median portion ; the median part is flattened, and is trans- 

 versely truncate behind j the lateral portions are slightly 

 curved downwards, and are produced behind into two pro- 

 cesses, which arch over and meet in the middle line. The 

 second abdominal segment has a narrow transverse depression
