TRTCHOMAGDALIS new genus. 



Very similar in general aspect and general structure to 

 Magdalis, differing as follows : Upper surface moderately to 

 rather densely pubescent, form more cylindrical, the elytra 

 not at all widened posteriorly ; beak straight, much shorter 

 than the prothorax, the latter strongly convex in profile, the 

 hind angles not produced or expanded ; elytra transversely 

 impressed before the apex ; fifth ventral segment as long as 

 the two preceding or nearly so. The claws are simple and 

 the femora unarmed, as in some species of Magdalis. 



Three Californian forms are known to me, all apparently 

 very rare. The first to be described [fasciatus) may be re- 

 garded as the type of the genus, but they are perfectly homo- 

 geneous in all essential characters. 



T. fasciatus n. sp. — Brown, integuments rugose and dull, rather 

 densely clothed above with coarse recumbent hair, which is bright 

 red-brown on the elytra, orange-red at the anterior margin of the pro- 

 thorax ; the basal half of the prothorax, base of elytra about the scu- 

 tellum and beneath the humeral umbone, a transverse median fascia 

 wider at the side margins, a lateral anteapical spot, and the apex 

 whitish cinereous ; pubescence beneath whitish, the posterior half of 

 the abdomen orange-red with some pale hairs intermixed, chiefly at 

 the middle and sides. The white hairs of the under surface and those 

 on the posterior parts of the pronctum are fine and conspicuously 

 plumose. Beak rather stout, two-thirds as long as the prothorax, 

 nearly straight, gradually widened apically, coarsely densely punctate 

 and glabrous. Antennae inserted at about the apical two-fifths, scape 

 curved, barely reaching the eye, first and second funicular joints about 

 twice as long as wide, the second a little shorter and narrower than the 

 first, third to seventh gradually shorter and slightly wider, the seventh 

 a little transverse; club cylindro-conical, as long as the five preceding 

 joints. Eyes not very convex, separated by a distance equal to two- 

 thirds the width of the beak at apex ; a frontal puncture between the 

 eyes. Prothorax as wide as long, sides strongly rounded, widest at 

 middle, feebly constricted anteriorly, basal margin narrowly reflexed 

 at sides ; surface densely but not coarsely rugose-punctate. Legs 

 moderately stout, femora nearly simple, tibiae strongly unguiculate at 

 apex, the outer angle also of the front tibiae produced in a short acute 

 spur ; tarsi as long as the tibiae, penultimate joint bilobed ; claws 

 small, simple. Length, 4-4.5 mm. ; width, L6-L8 mm. 



California: Pomona; Santa Monica; vicinity of San Fran- 

 cisco.
