Coleopterological Notices, IV. 685 



Body densely dull and velvety-black above, not in the least shining, the pro- 

 notiiin not transversely grooved at base; elytral strise but just visibly 

 coarser near the base, very finely, remotely punctate through(jut, the 

 punctures only slightly less minute laterally. Length 22.0 mm. ; width 

 8.7 mm Talidlis Lee. 



Body less dull, alutaceous, not at all velvety, the head and beak polished ; 

 punctures throughout larger and deeper ; pronotum with a deep entire 

 transverse groove before the basal margin ; elytral striae fine but very 

 deep, much coarser and more strongly punctate toward base, distinctly 

 and less remotely punctate throughout, the punctures distinct by un- 

 aided vision laterally and toward base ; elytra relatively less elongate. 

 Length LS-O-IG..*) mm. ; widtli 7.0-8.0 mm. Arizona. Three specimens. 



subnitens n. sp. 



Siibnifens is not to be confonnded with the individual variation 

 doscriljed by Dr. LeConte under the name procerus, the latter is 

 dull, opaque and velvety-black like the typical forms of validus. 



The dull lustre in this genus is caused, not by granuliform re- 

 ticulations, but by a beautifully regular system of extremely minute, 

 subcontiguous but not in the least confluent punctures, which are 

 deep and with the edges abrupt. In validus these minute punc- 

 tures are finer and deeper than in siibnitens ; in the latter each of 

 the fine sparse punctures of the intervals is surrounded by a pol- 

 ished ring, caused by an obliteration of the minute ground-sculp- 

 ture, while in validus these areolae do not exist. 



CALAXDRA Clairv. 



It is possible that this genus may have originated in the hypo- 

 thetical continent, represented at present by a few islands extending 

 from Ceylon to Madagascar ; several species are, however, now 

 endemic in the East Indies and one or two perhaps on the west 

 coast of South America. From these regions a number of species 

 have been distributed throughout the world in various kinds of 

 grain. It is quite impossible, therefore, to be sure of the native 

 country of any unfamiliar forms which may occur among us, and, 

 perhaps because of this uncertainty, the genus as a whole has been 

 neglected of late by systematic writers. 



In arranging the numerous examples in my cabinet I find four 

 widely distinct species and two subspecies. The true species, one 

 of which it is impossible to identify from published descrii)tions, 

 may be characterized as follows : —
