having a slight curve. Base of niesopleurse coarsely longitudinally 

 striated ; the upper part, except at the apex, obliquely and longi- 

 tudinally striated. Upper part of metapleuraj closely reticulated, 

 the lower stoutly obliquely striated. Abdomen smooth and shining, 

 the 2nd and 3rd segments closely punctured. 



The posterior coxse may liave a yellow mark on the 

 base and apex. Characteristic are the three yellow marks 

 in a triangle, on the metanotum.

 vertex, mandibles, except the teeth, palpi, two lines on the prothorax 

 next to the head, a line on the centre of the pronotum, tegulte, 

 scutellum, the apex of post-scutellum, two large elongated marks on 

 the apex of the metanotum, including the spines, and the ajiices of 

 the abdominal segments, yellow. The 5th to 12th antennal joints

Length 15-16 mm. 



Front and vertex stoutly striated in the middle, the strife stout, 

 irregular, semi-oblique, in places forming irregular reticulations ; 

 smooth and shining. Face and base of clypeus coarsely punctured ; 

 the apex of the clypeus smooth, serai-circularly depressed. Middle 

 lobe of the mesonotum closely punctured in the centre, the sides, 

 especially towards the ajiex, coarsely striated, the centre with a 

 broad shallow, but distinct, longitudinal depression ; the outer lobes 

 on the base and inner-side stoutly irregularly striated — scutellums 

 smooth, sparsely haired. Median segment strongly reticulated, 

 except at the base, where, in the centre, there is a small smooth space 

 behind the transverse keel ; the reticulations on the base laterally 

 are much weaker than on the rest of the segment. The teeth are 

 large, stout. Propleura), except at the base, strongly irregularly 

 striated ; the base of the meso- aljove coarsely rugosely punctured

Mesostenus caligatus, sp. nov. 



Length 9 ; terebra 2 mm. 5 . 



Very similar to M. salutator, but smaller ; there are no white 

 marks on the pleuras, the median segment is not so strongly reticu- 

 lated, but its base is distinctly punctured, almost as strongly as its
