531. PRYPNUS TIBIALIS n. sp. 



(^. Black. Densely clothed with ashen scales, thickly interspersed 

 with more or less decumbent setoe. 



Head with small dense concealed punctures. Rostrum with a 

 strong median carina, suddenly interrupted at apical triangle; the 

 latter somewhat uneven and its sides margined in depressions. 

 Antennaj moderately thin, first joint of funicle about once and one 

 half the length of second. Prothorax moderately convex, sides 

 strongly rounded, base not much wider than apex; surface vermi- 

 culate, the raised parts with small dense punctures; median line 

 distinct on basal half. Sciitellum absent. Mt/fra distinctly wider than 

 prothorax, almost parallelsided from base to apical fourth ; with 

 series of large, regular, partially concealed punctures; third and 

 fifth interstices feebly raised, the fifth with a tubercle at summit of 

 posterior declivity. Front tibice rather strong, each with two rather 

 small teeth about middle, and a strong triangular one near apex, 

 terminal hook acute and comparatively large. Length 12-15 mill. 



$. Differs in being somewhat larger and wider, with slightly 

 shorter legs, the front tibiae thinner and more regularly curved, 

 with a number of small almost regular teeth, and without the large 

 subapical one; and the median line of the prothorax more pronoun- 

 ced.

The absence of a scutellum should distinguish from tenebvicosus, 

 C'inaliculatus and fallax, in all of which it is described as being 

 present. The large subapical tooth combined with the apical hook 

 of the front tibiae of the male are somewhat suggestive of a nut- 

 wrench, and should prevent the species from being confounded 

 with any previously described one. On some specimens the rostral 

 carina is slightly bifurcated at its apex, but on others it is simple. 

 The deciduous mandibular processes are very short and stout, and 

 are present on all the specimens (6) before me. 



532. PRYPNUS GLABER n. sp. 



Black, shining; tarsi of a more or less dull red. Upper surface 

 sparsely clothed with short indistinct setse; under surface and legs 

 with denser (but still rather sparse) and longer whitish setae. 



iiead with small, dense, normally visible punctures. Rostrum with 

 a strong median carina, abruptly terminated just before apical 

 triangle; the latter somewhat depressed. Antennae thin; first joint
