Near T. secluloides Turn, but the hypopygium is differently 
shaped, resembling that of T. abstinens Turn. The colour of the abdo¬ 
men is very similar to T. rubellus Sm. 
Agriomyia bisecta sp. nov. 
5 . Clypeus finely punctured, without a carina, truncate broadly 
anteriorly; a short, shallow, longitudinal sulcus between the antennæ. 
Head flattened, nearly twice as broad as long, strongly rounded at the 
posterior angles ; the front opaque and finely shagreened, separated from 
the vertex by a delicate strongly arched carina, the vertex more polished 
and sparsely punctured. Pronotum much narrower than the head, mo¬ 
derately narrowed posteriorly, as long as the breadth on the posterior 
margin, convex, the anterior angles prominent, the anterior margin 
raised with a very short and obscure sulcus on the middle. Scutellum 
and pronotum shining, very sparsely punctured, the scutellum as long 
as broad, rounded at the apex. Median segment closely punctured and 
clothed thinly with long pale brown pubescence, nearly as long as the 
pronotum, narrow at the base, much broadened posteriorly and obli¬ 
quely truncate. Abdomen much broader than the thorax, shining, the 
first segment truncate anteriorly, broadly depressed at the apex, the 
raised portion before the apex not bilobed or emarginata posteriorly, 
a few scattered punctures above the truncation at the base ; second 
segment with five strong transverse carinæ including the raised apical 
margin; segments 3—5 delicately aciculate at the base, sparsely punc¬ 
tured near the apex, the extreme apex smooth. Pygidium almost verti¬ 
cally depressed, more than twice as long as the greatest breadth, elon¬ 
gate ovate, narrower at the base than at the apex, narrowly truncate 
at the apex; the dorsal plate with the sides raised and with a low 
median carina, truncate at the apex, the ventral plate extending much 
beyond the dorsal. Fourth and fifth ventral segments coarsely punctured 
and thinly clothed with long golden pubescence. Tarsal ungues bifid.
