an. Posterior transverse silvery line of clavus and corium dislocated and 



projected forward on commissure. 



b. Joint 2 of antennas shorter than the distance between tip of tylus 



and basal margin of pi-onotum; smaller, length not exceeding 



3.5 mm. 



c. Beak scarcely reaching hind margin of mesosternum; inner por-

 transverse line with that on clavus. 864. walshii. 



cc. Beak reaching middle of hind coxae; inner portion of interrupted 

 posterior silvery band projected forward and forming a trans-

 bb. Joint 2 of antennae as long as or longer than distance between tip 

 of tylus and basal margin of pronotum; larger, length 4 or more

d. Clavus of the same brown color as corium; joint 2 of antenna? 



subequal in length to distance between tip of tylus and base of 

 pronotum. 866. brunneus. 



dd. Clavus distinctly darker bordering scutellum and commissure; 

 joint 2 of antennae distinctly longer than distance between tip 

 of tylus and base of pronotum. 867. clavatus. 



863 ( — ). Pilophorus perplexus Douglas & Scott, 1875, 101. 



Head, pronotum and scutellum fuscous-brown to blackish ; elytra 

 uniformly dark brown clothed with minute yellow pubescence, the poste-

 of vertex; 2 brown, darker toward apex, nearly five times as long as 1; 

 3 and 4 fuscous, paler toward base, 3 two-fifths as long as 2, male, four- 

 fifths as long as 2, female; 4 slightly shorter than 3, male, one-half the

Hollington and Woodstreet, England, August (British Mus.

Head in great part dull reddish-yellow, the base of vertex fuscous; 

 pronotum fuscous-brown, subopaque; scutellum dark brown, shining, with 

 a row of silvery scales each side; elytra dull yellowish, sometimes darker, 

 with two narrow silvery bands as in amoznus, the hind one projected 

 slightly forward on claval commissure, the inner half of the area behind 

 it of the same hue, the outer half and cuneus a polished fuscous-brown; 

 inner basal angle of cuneus with a silvery spot; membrane dusky; legs 

 and under surface in great part dull reddish-yellow, coxae paler; hind
