426 Mr. D. Shai*p's description of a neiv yenus, ^'c. 



with the 6th, 7th and apical segments yellow, rather 

 sparingly and not coarsely ]iunctured. Legs tawny, with 

 the coxiv iniiiscate. The middle of the sternum also infus- 

 cate. 



The male has the hind coxre armed with an elongate 

 spine, projecting backwards and slightly curved outwards ; 

 the ventral plate of the 6th segment of the hind body has 

 in the middle, near the base, two small patches of pale 

 pubescence, separated by a narrow shining space, while 

 tlie hind margin of the folloAving segments has a mode- 

 rately large excision in the middle.

Obs. — This is a very distinct s]iecies, to be placed at 

 one extremity of the genus, with G. vcstitus and its allies 

 at the other; the only individual I have seen has lost its 

 antennte, except the three basal joints. 



Sel^ia (n. gen. Staj)hylininorinti). 



Corpus pubescens. 



Antennae intus subseiTatfc. 



Palpi omnes articulo ultimo dilatato. 



Thorax lineis lateralibus hand conjunctis. 



IVIandibles rather short, sinuate on their inner margin 

 towards the base, but without distinct tooth. ]N[axillai-y 

 palpi with the first joint very short, 2nd stout, longer than 

 broad, 3rd a good deal shorter than 2nd, but not quite so 

 thick, 4th longer than any of the others, and a good 

 deal dilated. Labial palpi with the two basal joints short 

 and stout, the 3rd quite as long as the other tAvo together 

 and dilated from the base towards the apex ; mentum very 

 short and very broad. Thorax Avith the side ])iece broad, 

 and much produced inwardly over the spiracle, which is 

 hence hidden ; its lateral margin fomied by the upper line, 

 which is a good deal deflexed at the front angle, but only 

 joins the lateral line on the front margin at the side of the 

 neck. Middle coxai widely separated, and with a wide 

 space between the meso- and meta-sternal ])rocesses. 

 Dorsal segments of hind body without curved lines. Front 

 tarsi dilated ; front tibia? also broad and without spines ; 

 middle and hind tarsi rather broad and flattened from 

 above. 



The peculiar insect for which I propose this generic 

 name has caused me great hesitation as to its affinities. 

 I think on the whole the most probably correct place I can
