Phacemastix poultoni, sp. nov. (Plate LXVII. fig. 2.) 



Long. 64-7i, lat. 2|-3| mm. 



Colour black, j)rothorax with a ring of sparse white or yellowish 

 scaling round the entire apical margin and a small patch of 

 similar scales at each basal angle ; elytra dark red, v.^ith the base 

 and apex broadly black and with two broad transverse bands of 

 white scales, one at the extreme base and the other dividing the 

 red from the apical black ; under parts black, with more or less 

 sparse white scaling, forming denser patches on the meso- and 

 metasternum. 



Head subconical, closely punctured ; eyes large, convex and 

 meeting dorsally in both sexes. Rostrum as long as prothorax, 

 curved and strongly deflected, its sides subparallel ; apical portion 

 flattened, bare and coarsely punctured throughout ; basal portion 

 somewhat compressed superiorly, with three dorsal carinfe, the 

 two outer ones uniting near base with the central one, which is 

 more elevated and ascends the forehead, the sides rugosely punc- 

 tured and with sparse white scaling. Antennce dark ferruginous, 

 with white setfe ; the club fuscous, shorter, about equal to the 

 last three joints of the funicle. Prothorax as broad as long, sides 

 scarcely rounded, broadest at base and gradually narrowed to near 

 apex, where there is a sharp constriction, base deeply bisinuate, 

 apical margin shallowly sinuate dorsally ; upper surface moderately 

 convex, with deep subreticulate punctviation throughout and with 

 only a trace of a central carina. Elytra jointly sinuate at base, 

 broadest at shoulders, which are roundly prominent, and thence 

 gradually narrowed to apex ; upper surface almost plane, depressed 

 near the scutellum, which is black, bare, and rugosely punctured ; 

 the strige broad and deep, containing rows of large shallow punc-

-l-t is with much pleasure that I dedicate this species to my 

 kind friend Prof. E. B. Poulton, F.R.S., the Hope Professor of 

 Zoology at Oxford, to Avhom I am deej)ly indebted for much 

 invaluable aid in my entomological work. 



P. haridioides Fahr. is the only other described species of this 

 genus, and has a strikingly diflferent coloration from any of the 

 foregoing insects.
