TENEBRIONHLE 183 



It is possible that the Ologlyptus planatus of Champion, may also 

 belong to this genus or that it is closely related. 



Form rather slender and graceful, dull brown, the suture and two lines 

 on each elytron faintly paler; head coarsely and closely punctate; 

 prothorax more than one-half wider than long, slightly narrower 

 between the basal than the apical angles; apex deeply sinuate, the 

 base bisinuate, the sides regularly arcuate; surface flat, the margin 

 broad and widely reflexed, the edge slightly crenulate and with short 

 hairs; punctures sparse, each with a short hair; elytra less than 

 twice as long as wide, widest at the middle, the humeri very oblique, 

 the lateral margins sharp and slightly reflexed, suddenly incurved at 

 apical fourth, thence oblique nearly to the apex; surface nearly flat 

 transversely and having sparse erect spinules of peculiar structure, 

 they being pectinate on two edges as in the tibial spurs of Priono- 

 chccta; prosternum sparsely punctate, with short and erect hairs, 

 the propleura more coarsely punctate; abdomen finely and sparsely 

 punctate and with short erect spinules; legs roughly punctate and 

 with short hairs. Length 15.0 mm. Lower California (San Jose 

 del Cabo. [Asida embaphioiiides Horn] embaphionides Horn 



Form more slender, the sides of the elytra more reflexed and forming a 

 lobe-like projection on the declivity, very slender and elongate, 

 dark castaneous, feebly shining and with short sparse fulvous hairs, 

 the elytra with short and scattered erect black setae; head very 

 coarsely and roughly punctured, the neck more finely and densely 

 as usual; prothorax slightly wider than long, the apex deeply sin- 

 uate, the sides rather strongly arcuate, very slightly sinuate pos- 

 teriorly, the base feebly bisinuate, the hind angles right; surface 

 flat medially, coarsely punctate at the sides, which are widely re- 

 flexed; elytra slightly wider than the prothorax and about three 

 times as long, the surface rather flat, rapidly declivous posteriorly, 

 the side margin acute, not widely reflexed, terminating at the de- 

 clivity in a lobe-like process, sparsely and indistinctly punctate, 

 each puncture with a fulvous [previously said to be black] hair or 

 short spine; deflexed sides sparsely spiculose; under surface sparsely 

 punctate and with very short erect spinules; prosternum concave 

 between the coxae; legs slender, clothed with short hairs, the outer 

 apical angle of the front tibiae slightly prolonged. Length 13.5 mm. 

 Lower California (San Jose del Cabo). [Asida flaccida Horn]. 



flaccida Horn 



Although Dr. Horn surmised that flaccida might be the male of 

 embaphionides, I am not convinced, on studying the very good 

 figures of these species, that they are even congeneric, but if not a 

 Platasida, there is no other place for flaccida among the genera here 

 recognized. The elytral setae appear to be simple in flaccida, or, 

 at any rate, nothing to the contrary is stated and this, together 

 with the basally sinuate sides of the prothorax, would alone show
