12 Mr. Cameron on a 



vertical part rugosely punctured ; while in IFrtZ(vr/ the apex 

 is concave, with indistinct lateral tubercles, the perpendicular 

 part not rugosely punctured. The wings hardly reach to 

 the end of the metathorax, and seem to be infuscated in 

 the middle. 



Betyla, gen. nov. 



Eyes hairy. Antennae 15-jointed; the basal joint as 

 long as the six following united ; joints 2 — 7 longer than 

 broad ; joint 8 thicker than 7th, nearly longer than broad ; 

 the 9th still thicker ; 9 — 14 much broader than long ; the 

 15th twice longer than broad; sharply conical. Head 

 forming a broad snout before the antennse ; narrowed before 

 and behind the eyes. Thorax narrow, ant-like, narrowed 

 between the meso- and metathorax ; the former bearing in 

 front a stout tooth on either side, the scutellum not defined ; 

 parapsidal furrows absent ; metanotum without keels or 

 furrows.. Apterous. Abdomen much broader than the 

 thorax, the petiole longer than broad, stout ; the second 

 segment very large, occupying dorsally the greater part of 

 the entire abdomen, and with a distinct margin at its junction 

 with the ventre. The third and fourth segments together 

 the length of the petiole. There are apparently five ventral 

 segments. Petiole on lower side projecting into a large, 

 stout, tooth-like process. Femora clavate. 



This genus belongs to the Belytidce. The only genus 

 with which it could be confounded is Miota, which has an 

 abdomen with three dorsal segments, of which the second is 

 very much lengthened, and reaches near to the tip. Miota 

 is winged, has only three dorsal segments, and no mention 

 is made of any peculiarity in the form of the thorax ; nor 

 of the absence of ocelli. In fact, Foerster's analytical 

 tables are hardly capable of being used for the identification 

 of the extra European genera ; and so far as I know the 

 type of Miota has never been described.
