upper-winii; " contracted." Though not a very large insect, its general 

 appearance is rather striking ; and there is nothing for which it could 

 be easily mistaken by any one fortunate enough to captin-e it. 



Pachijjjrotasis, Htg. — This is a genus whose characters, once 

 grasped, are easily recognised in all its species, viz., the extremely 

 elongate hind coxae, which ally it with Macropliya, and the long, 

 slender antennae, which at once distinguish it from that genus. One 

 of its species (rapfe) is abundant in almost every district ; another 

 {antetmata) is local, but not at all uncommon in the New Forest ; 

 a third (variegata) seems to be rare — my only British specimens of 

 it, all of which are ? ? , were taken long ago by Dr. Capron. Our 

 fourth and last species, simulans, is exceedingly rare ; in fact, I only 

 know of two British captures of it. Mi-. Bridgman's J* from Norwich 

 (recorded in the Monograph), and a v , taken by Mr. Donisthorpe at 

 Darenth in June, 1909, which he has very kindly added to my 

 collection. 



These insects, at least in dried specimens, have a characteristic 

 " piebald " coloration — black and white, the white sometimes inclining 

 towards yellow. But sometimes, at least, in life the pale parts are of 

 a beautiful (but sadly evanescent) green. My first captures of 

 antemmia while fresh exhibited this tint to perfection, and I felt quite 

 distressed when, within a few days, they faded to a dirty white !
