Fulvous orange; scutellum, postscutellum, median segment, 

 basal segment of the abdomen, second and third ventral segments, 

 pleura?, thorax beneath, coxa?, trochanters, and base of the femora, 

 black. Wings flavo-hyaline, very faintly clouded at the apex. 



Length 19 mm. 



Hah. Mackay, Q. (Turner). December. 



Resembles G. darivinii in colour, but the legs and antennae are 

 much shorter. The mesonotum is also much smoother and the 

 median segment is striated. 



Cryptocheilus sathanas, sp. n. 



9 . Clypeus convex, more than twice as broad as long, opaque 

 and sparsely punctured, the apical margin depressed and very 

 narrowly shining. Inner margins of the eyes almost parallel, 

 slightly diverging towards the clypeus ; posterior ocelli as far 

 from each other as from the eyes, the eyes touching the base of 

 the mandibles. Antenna? moderately stout, as long as the thorax 

 and median segment combined ; the second joint of the flagellum 

 more than half as long again as the third. Head opaque, almost 

 smooth, a short longitudinal sulcus between the antenna?. Pro- 

 notum more than half as long as the mesonotum, the anterior 

 angles strongly rounded. Thorax opaque ; the mesonotum with 

 an impressed, longitudinal, median line which is continued on the 

 base of the scutellum. Median segment nearly twice as broad at 

 the base as long, vertically truncate posteriorly, rectangular, with 

 a deep median sulcus, indistinctly transversely striated on the 

 apical half. Abdomen opaque, pruinose, the apical segment de- 

 flexed, rounded at the apex. Anterior tarsi with very short spines 

 on the basal joint, posterior tibia? serrate ; tarsal ungues with one 

 tooth on the inner margin. Radial cell pointed at the apex ; first 

 recurrent nervure received at two-thirds from the base of the 

 second cubital cell, second at the middle of the third cubital cell ; 

 second abscissa of the radius shorter than the third ; cubitus of 

 the hind wing originating before the transverse median nervure. 



Entirely black : wings dark fuscous without coloured reflections. 



Length 25 mm. 



Hah. Port Darwin (Turner). November. 



Cryptocheilus erythrothorax, sp. n. 



2 . Clypeus short, much broader than long, slightly convex, the 

 apical margin very feebly and widely emarginate, almost trans- 

 verse. Eyes scarcely separated from the base of the mandibles, 

 converging a little towards the vertex, where they are separated 

 by a distance about equal to the length of the third joint of the 

 flagellum ; posterior ocelli considerably further from the eyes than 

 from each other. Antenna? rather slender, as long as the head, 

 thorax and median segment combined ; the second joint of the 

 flagellum a little longer than the third. Pronotum narrowed and 

 rounded anteriorly, the posterior margin arched, more than half 

 as long as the mesonotum. Median segment as long as broad,
