160 SHUCKARD ON THE 



The male. I can detect no difference between the insect I possess, 

 as the male of this species, and the male of the preceding, with 

 the exception of the slighter exsertion of the fifth abdominal 

 segment, and the colour of the head and thorax being more blue. 



The female has the head bronzy, inclining to coppery ; the scape of 

 the antennae bronzy above, red beneath ; and the two first joints 

 of the flagellum also red, the rest black ; vertex and face with 

 scattered deep punctures : prothorax testaceous ; mesothorax 

 bronzy black, both slightly punctured ; metathorax blue and 

 rugose ; legs testaceous : the intermediate and posterior coxae, 

 trochanters, and femorae, of a bronzy black : abdomen shining 

 testaceous, with the posterior half of the third segment black, and 

 the fourth steely-blue : ovipositor exserted. 



I believe this species has not occurred near London ; it has 

 been found in Suffolk, by Mr. Rudd, and it has also occurred 

 in the New Forest, Hants. The male is not yet fully or well 

 determined ; the difTerences between the one I have received as 

 such fi'om my friend, the Rev. G. T. Rudd, and the preceding 

 species, are too slight to admit of my considering it determi- 

 nate, for I have carefully examined it under a lens of high 

 power. 



Genus II. — Chrysis, Litm. 



Head transverse, as wide as the thorax, which is truncated anteriorly 

 and posteriorly, and the metathorax has a minute tooth on each 

 side : abdomen consisting of three segments, the third being 

 sulcated towards its extremity, and along the margin of this sulca- 

 tion it has a row of minute fossulets : the apex frequently dentate, 

 but the teeth, in some species, obsolete, or entirely deficient : the 

 superior wings with a marginal and first and second discoidal 

 cells complete, and a first apical cell nearly complete : the radial 

 iiervure forms an angle (except in Chr. cyanea, where it is 

 rounded,) and the second discoidal is quadrangular (except in 

 Chr. neglecta, where it is triangular) : legs moderate. 



The insects of this genus possess the power of rolling them- 

 selves up into a ball upon the approach of danger. They are 

 supposed to be parasitic, but their history is not known, as 

 their earlier stages have not been ascertained. They are to be
