as wide, the collar very short, the parapsidal furrows indicated 

 anteriorlj, convergent ; axillae small, indistinctly separated from 

 the parapsides. "Wings hyaline, tegulse and venation pale

Described from a single specimen. 



Chetsogltphe, gen. nov. 

 Allied to Glyphe, Walker, but with the following diflFerences : — 

 Head very wide, with the eyes nearly twice as wide as the 

 thorax, the vertex very broad, the ocelli subtriangularly arranged 

 and rather close together, the laterals being only one and a half 

 times their diameter from the front ocellus, but full three or four 

 times their diameter from the border of the eye. Eyes very large, 

 occupying nearly the whole side of the head, and leaving only a 

 short space between them and the mandibles. Both mandibles 

 4-dentate. Antennae 13-jointed, filiform, pilose, the pedicel a 

 little shorter than the first f unicle-joint ; ring-joints 2, minute ; 

 funicle 6- jointed, the joints a little less than twice as long as 

 thick ; club 3-jointed. Thorax ovate ; pronotum visible from 

 above only as a slight transverse Hne, but in reality it is trian- 

 gular, the triangular portion being usually hidden in the occiput 

 of the large broad head ; mesonotum about twice as wide as long, 

 with only slight indications of parapsidal furrows anteriorly ; 

 axillae large and projecting obliquely forward into the field of 

 the parapsides a little beyond the base of scutellum ; meta- 

 thorax short, but with a prominent punctate neck, as in Ptero- 

 malus, to which the abdomen is attached, the petiole being 

 exceedingly short ; spiracles oval, close to the metathoracic band, 

 and with a sulcus. Wings pubescent, the marginal vein long, 

 fully two thirds as long as the submarginal, or twice or more than 

 twice as long as the stigmal, the latter clavate, very slightly curved; 

 postmarginal almost twice as long as the stigmal. Abdomen 

 conic-ovate, the venter towards base usually acutely triangularly 

 carinated, the first body-segment the longest, as long as 2, 3, 

 and 4 combined, these about equal, 5th a little longer than 4th, 

 6th almost as long as the basal segment, 7th conic, a little 

 shorter than the 6th ; sheaths of ovipositor slightly prominent.
