3. Apical joint of the flagellum longer than the penulti- 
mate, moderately curved and blunt at the apex; the penulti- 
mate and two preceding joints bluntly produced at the apex 
beneath; the seventh and eighth joints with a minute 
tubercle at the base beneath. Fore tarsi not dilated; the 
basal joint with eight spines, the six basal spines stout and 
black and of uneven length, the first and sixth being much 
shorter than the others, the two apical spines short and 
yellow, widely separated from the basal row. Intermediate 
femora strongly serrated beneath, intermediate tibie not 
produced at the apex, basal joint of the intermediate tarsus 
normal. Second sternite with a prominent carina on the 
apical half; sixth sternite with a triangular prominence at 
the apex; seventh with a longitudinal carina. Seventh 
tergite narrowed to the apex, where it is narrowly truncate. 
Claspers broad, concave above, ciliate on the outer margin, 
the apex narrowed and deflexed, not pointed or hooked. 
Fore wings a little more than twice as long as the breadth of 
the thorax ; one vein only emitted from the apex of the 
median cell. 
2. Second sternite very closely and finely punctured, not 
shining in the middle ; sixth tergite rather narrowly rounded 
at the apex. Basal joint of the fore tarsus with eight black 
spines, the spines in an even row, long and stout, the basal 
one only short.

This very distinct species is perhaps nearest to albofasciata, 
Sm., though differing much in the structure of the antenne 
and genitalia, and in the spines of the fore tarsus. The 
genitalia somewhat resemble those of B. bubalus, Handl. 
Subfamily Larrivz. 
Tachytes exclusa, sp. n.
