occasionally happens, are excessivel}' like Evagetes, but easily dis- 

 tinguished by the greater length of the second cubital cell, which is 

 about twice as long as its greatest height — in Evagetes much less than 

 twice- — and by the very strongly curved outer ti-ansverse cubitus — in 

 Evagetes nearly straight, but oblique.] 



PSAMMOCHARES Latr. 



P. pectin /j)es, as may be inferred from the remarks above, is 

 practically an Evagetes with (normally) three cubital cells and has thick 

 antennae in both sexes unlike any of our other red-bodied species, the 

 third joint in the $ being only subequal in length to the scape. 



The two red-bodied species viaticus and chalyheatus and the three 

 black species approximattis, nigerrimus, and cardui are thrown together 

 by the structure of the claws in the 6 , these being cleft, the lower tooth 

 shorter and in some aspects often blunt or truncate. The females of all 

 these have a comparatively densely-haired 6th dorsal segment, the hairs 

 bristl}', denser than and unlike thohiC on the 6th ventral. 



The two red-bodied species have a perfectly developed pecten to the 

 front tarsi, the second joint having an elongate .spine on the outer edge 

 towards the middle, as well as the one at the ajjical angle. 



The black species have no proper pecten, and there is no elongate 

 spine on the outer side of the second tarsal joint. 



P. nigerrimus is, according to Ashmead, the type of the genus 

 Anoplius Lep., and no doubt sooner or later the generic distinction of 

 these black-bodied species will be recognized. 



P. rujipes is isolated ; the S has cleft claws like the preceding, but 

 otherwise it differs greatly both in superficial appearance, in its peculiar 

 vestiture, and other respects. The females lack the dense hairiness of 

 the 6th ventral segment and the pecten is more developed than in any 

 other of our species, the long spines of the 2nd and 3rd tarsal joints 

 being longer than the elongate joints themselves. 



Ashmead cites ruftpes as being the type of Episiiron Schiodte, and 

 this genus (with probably many foreign allied species) will no doubt be 

 accepted as distinct fi'om Anoplius, etc. The characters given by this 

 author are some of them incorrect and some of no value. 



All the rest of our British Psammochares have only a small tooth 

 on the 6 claws beneath, the tooth being often difficult to see. 



P. spissus and minutulus are red-bodied and allied, the $ $ with 

 only short spines on the front tarsi and no proper pecten.
