c? . Niger ; segmentis abdoininalibus margine apicali anguste 

 brunneis; tegulis tcstaceis ; feinoribus apice extremo, tibiis 

 tardisquo fulvo-ferrugiiieis; alis tlavo-hjaliiiis, venis ferrugiiieis; 

 froiite clypeoque pallide aureo-pubesceiitibus ; thoraco seg- 

 mentoque mediaiio griseo-aureo pubescontibus ; segmentis dorsal- 

 ibus 4 basalibus fascia interrupta apicali argenteo-pubescente ; 

 area pj'gidiali pallide aureo-pubesceiite ; galea modice elongata, 

 scapo dimidio longiorc. 



Long. 11 mm. 



cJ. Clypeus very broadly rounded at tlie apex, -with three 

 minute teeth on each side ; vertex rather closely punctured ; 

 eyes sejiarated on the vertex by a distance not quite equal 

 to the length of the second joint of the flagellum ; secoiid 

 and third joints of the labial palpi subequal. Thorax closely 

 microscopically punctured ; median segment about half as 

 long again as the scutellum. Second sternite finely but not 

 very closely punctured, thinly clothed with long fulvous 

 hairs ; seventh tergite broadly rouuded at tiie apex; eighth 

 ventral segment strongly emarginate, the apical angles 

 bluntly produced. Basal joint of fore tarsi with four spines ; 

 spur of hind tibiae as long as the basal joint of the hind 

 tarsus. Radial cell narrowly rounded at the apex ; third 

 abscissa of the radius a little longer than the second, but 

 slightly shorter than the space between the recurreut 

 nervures on the cubitus.

In the length of the galea this species is nearly allied to 

 T. separabilis^ from which it is separated by the smaller 

 size, the rounded apex of the seventh tergite, and the lesser 

 number of spines on the basal joint of the fore tarsus. In 

 the latter case it is possible that the normal number of 

 spines in this species may be five, as they are liable to be 

 broken, but certainly not six as in separabilis.
