apex, the triangular surface sliining, with large scaftererl 

 punclures, the apical margiu transver.se. Eyes separated on 

 the vertex by a distance equal to twice the length of the 

 second joint of the flagellmn ; the third joint of the flagelluni 

 about as long as the first and second conibined. Head and 

 thorax very finely and closely punctured; median segment 

 oijaque^ very finely granulate, the sides not striated; the 

 posterior slope transversely striolate towards the apex, with a 

 deep depression at the base. Abdomen highly polished; 

 pygidial area elongate, rather sparsely and finely punctured. 

 Tlie long spur of the hind tibiaj 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 nariower than in T. pectinipes ; the second abscissa of 

 the radius scaicely 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 2\ pectinipes^ ta 

 which it is allied in the form of tliC pygidial area.

This Mediterianean species occurs at Harar (6^. Kiisten- 

 sen). A subspecies occurs at Salisbury, Mashonaland 

 (6^. A. K. Mar.sltall) , in which the sculpture of the median 

 segment is much coarser, there being very distinct divergent 

 striae at the base, whereas the strise, as far as they are deve- 

 loped mjiicornis, are ))arallel. For this I suggest the name 

 T(ic/itjSj/he,i\filiconiis excerptas, subsp. n. 



I do not regard the scul[)ture of tlie median segment as a 

 very reliable character in this genus, considering that it is 

 liable to considerable variation in some species.
