apex, the triangular surface shining, witli large scaftererl 

 punctures, the a[jical margin transverse. Eyes separated on 

 the vertex by a distance equal to twice t!ie length of the 

 second joint of tiie flagellani ; the third joijit of the flugellum 

 about as lono- as the liist and second combined. Head and 

 thorax very finely and closely punctured; median segment 

 opaque, very finely granulate, the sides not striated; the 

 posterior slope transversely &ti iolate towards the apex, with a 

 deep depression at the base. Abdomen highly polished; 

 pvgidial area elongate, rather sparsely and finely punctured. 

 The long spur of the hind tibiai distinctly shorter than the 

 basal joint of the hind tarsus; spines of the fore tarsus 

 forming a comb, slender and fairly long. Radial cell longer 

 and narrower than in T. pectimpes ; the second abscissa of 

 the radius scarcely shorter than the third.

The sculpture of the median segment resembles T. lati- 

 frons, Kohl, from which it differs in other details. The eyes 

 are further a| art on the vertex than in T. pectinipes^ to 

 which it is allied in the form of the pygidiul area.

This Mediterianean species occurs at Harar {G. Krif^ten- 

 seu). A subspecies occurs at Salisbury, Maslionaland 

 (tr. A. K. Marshall), in which the sculpture of the median 

 segment is much coarser, there being very distinct divergent 

 strioe at the base, whereas tlie strife, as far as they are deve- 

 loped in Ji<icornis, are parallel. For this I suggest tlie name 

 Tacliyspliex Jilicornis excerptus, subsp. n. 



I do not regard the sculpture of tiie median segmeiit as a 

 very reliable character in this genus, considering that it is 

 liable to considerable variation in some species.
