5O MEMOIRS ON THE COLEOPTERA 



patch of denser punctures and pubescence; prosternum rather 

 strongly punctate, the punctures separated by nearly twice their 

 diameters. Length 1.5 mm.; width 0.75 mm. Georgia. [Limnichus 

 nitidnlus Lee., Proc. Acad. Phila., 1854, p. 1 17]. . .nitidulus Lee. 

 Outline, color and lustre nearly as in nitidulus but slightly narrower, the 

 sides rounded, gradually ogival posteriorly but with the tip of the 

 elytra rather more obtuse and sublobate; pubescence rather less 

 sparse, finer, shorter, rather persistent and almost uniformly dusky- 

 cinereous in color, less conspicuous; head with pliciform sculpture, 

 replaced posteriorly by rather coarse, very close-set punctures, 

 which are somewhat laterally compressed; prothorax not quite so 

 short as in the preceding and with the converging sides not straight 

 but feebly arcuate, the median line and punctures similar, the latter 

 becoming rather more notably stronger though not closer laterally, 

 where the interspaces have a very feeble and subobsolete micro- 

 reticulation, observable only with difficulty; elytra nearly similar 

 though not quite so elongate, the apex narrowly obtuse and lobiform. 

 the punctures more than twice as large as those of the pronotum but 

 relatively shallow and very broadly impressed, separated by rather 

 more than twice their diameters; abdomen with rather strong though 

 well separated punctures, the last segment (d 71 ) strongly, very closely 

 punctate throughout, the punctures gradually becoming fine and 

 very dense in a small, subapical, unimpressed opaque spot on which 

 the hairs become slightly longer and denser but scarcely paler and 

 inconspicuous; prosternum nearly as in the preceding. Length 

 1.5 mm.; width 0.7 mm. Rhode Island (Boston Neck). 



sculpticeps n. sp. 



The species named analis by LeConte, is definitely restricted 

 in the above table to those individuals, the largest of the genus, 

 occurring somewhat abundantly in the coast regions south of San 

 Francisco; several allied forms occur, also abundantly as a rule, 

 in the desert regions of Arizona and Colorado, two of which are 

 defined above under the subspecific names rugiceps and coloradensis. 

 The Colorado form is quite distinct, having sparser and more easily 

 denuded vestiture, a more oblong parallel outline and much longer 

 elytra. Both of these forms are probably specific in value, rather 

 than subspecific, but are left with the latter status for the present; 

 they were all thrown together under the name analis by LeConte 

 and in my previous revision, but it is well to have the typical form 

 fixed as a foundation for future work. The very few words forming 

 the original description of californicus are largely erroneous or 

 misleading, it being stated that the last ventral segment has no dense 

 central pubescence and that the elytra are strongly punctured; 

 relatively to perpolitus the latter statement is passably correct, but
