the prothorax, scutellum, and elytra, the elytral strie broader, deeper, more coarsely 
punctate. 
2. Psomus quadrinotatus, sp. n. (Lab. VIII. figg. 7, 7a.) 
Subrhomboidal, very convex, shining, piceous, the eyes black, the rostrum, antenne, tibie, and tarsi flavo- 
testaceous; the prothorax with a large triangular space on each side, extending down the flanks, the 
scutellum, a large subtriangular spot beyond the middle of each elytron, and a patch on the mesosternal 
side-pieces, densely clothed with coarse white scales, the rest of the vestiture of the upper surface 
brownish, sparse, fine, and hair-like, that of the rostrum, legs, and under surface coarse and white. 
Head finely punctate. Prothorax conical, closely punctate. Elytra finely punctate-striate, the interstices 
uniseriate-punctate and almost flat. 
Length 1,%,, breadth 1 millim. 
Hab. Panama, Bugaba (Champion). 
The large dense white spot on each side of the prothorax and on the outer part of 
the disc of each elytron, the closer hair-like vestiture on the rest of the upper 
surface, and the flattened uniseriate-punctate elytral interstices readily distinguish 
P. quadrinotatus from P. caseyi and P. politus. 
3. Psomus violaceus, sp.n. (Tab. VIII. fig. 8.) 
Subrhomboidal, very convex, shining, black, the elytra violaceous, the antenne, tibia, and tarsi rufo- 
testaceous ; the elytra clothed with a few scattered brownish, curled, decumbent, bristly hairs, the scutellum 
with white scales, the vestiture of the under surface and legs very fine, sparse, white, and hair-like. 
Head finely punctate. Prothorax conical, closely punctate, except along the smooth median line. 
Elytra finely and narrowly punctate-striate, the sutural stria broader and deeper, the interstices flat 
and with a few scattered minute punctures. 
Length 13, breadth 1 millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
Recognizable by the sparse, fine vestiture, the violaceous, finely-striate elytra, and 
the flat elytral interstices. 
PHILINNA, gen. nov. 
Head globose; rostrum long, filiform, strongly arcuate throughout, the antenne inserted far from the base 
the funiculus 6-jointed, joint 2 nearly as long as 1, the others shorter, the club stout, acuminate-ovate, 
with its basal joint short, not longer than the second; eyes oval, in great part exposed, rather large, 
narrowly separated; prothorax short, convex, subconical, bisinuate at the base; scutellum small; elytra 
broad, rounded-subquadrate, separately rounded at the apex, leaving the vertical pygidium exposed, the 
humeri prominent, but obtuse; rostral canal deep, confined to the prosternum ; anterior coxe unarmed, 
narrowly separated, the prosternum with a short truncated ridge behind each of them; mesosternum 
vertical, slightly swollen on each side between the middle coxe, the latter widely separated, the meso- 
metasternal suture sinuate; metathoracic episterna very broad; ventral segments gradually ascending, 
3 and 4 short ; legs short; femora unarmed, the posterior pair not reaching beyond the apex of the 
abdomen ; tibie unguiculate at the inner apical angle in the g only, the intermediate and posterior pairs 
with a fringe of short sete at the outer angle ; third tarsal joint strongly bilobed ; tarsal claws simple ; 
body subovate, strongly setose, and also clothed with piliform and pectinate scales.
