GG Mr, R. E. Turner's Notes on the Thynnidss, 



Thynnus siccus, n. sp. 



(J. Clypeus much produced, broadly truncate at the apex and 

 irregularly longitudinally striated. Labrum narrowed to the apex, 

 projecting much beyond the clypeus. Antenna) as long as the head 

 and thorax combined. Head rather small, narrower than the thorax, 

 closely and finely punctured, the interantennal prominence broadly 

 V-shaped and a short longitudinal carina between the antenna). 

 Thorax finely and clo.sely punctured ; the pronotum very broadly, 

 but slightly, emarginate anteriorly ; the scutellum rounded at the 

 apex, the postscutellum covering the median segment which is 

 vertically truncate. Abdomen closely punctured ; the three basal 

 segments of about equal breadth, the first vertically truncate an- 

 teriorly. A very short spine on each side at the apical angles of the 

 sixth ventral segment. Dorsal plate of the epipygium produced 

 from the base and longitudinally striated. Hypopygium longitudin- 

 ally striated above, with a spine on each side near the base, thence 

 narrowly produced, subtruncate at the apex, with an acute apical 

 spine. 



Light yellow ; the antenn,-c, a broad band on the vertex between 

 the eyes, advanced in the middle and surrounding the ocelli, con- 

 nected on each side with a longitudinal line reaching the base of the 

 antennae, a spot on each side of the clypeus below the base of the 

 antennae, the short frontal carina, a small oblique sjDot on each side 

 of the pronotum, the sides of the raesonotum and a large semi- 

 circular mark on the anterior margin, the mesosternum, the basal 

 and ajiical margins of the six basal abdominal segments and the 

 whole of the seventh segment black. Wings hyaline, nervures 

 fuscous. 



Length 17 mm.

Tchphoromyia 2Jcrnvic(7U( , n. sp. 



(^ . Mandibles very broad, slightly but very broadly emarginate 

 on the basal half of the outer margin, curved inwards near the apex 

 and terminating in an acute tooth ; a tooth on the inner margin at 

 the base of the apical tooth and another above it near the middle of 

 the inner margin, the margin between the two teeth forming a sharp 

 cutting edge ; another ])rominent tooth above, the mandible from 

 the outer margin to the tooth nearly half as broad as the total length, 

 the inner margin slnu'iily angulated at the last tooth, the apical
