146 MEMOIRS ON THE COLEOPTERA 



Form and general characters almost as in illini throughout, including the 

 male sexual characters, except that the apical acute process of the 

 middle tibiae is a little stronger and more prominent, but having a 

 stouter body, with broader elytra, only one-half longer than wide 

 and fully a third wider than the prothorax, the striae being more 

 distinctly punctate, more obsolete apically and with the intervals 

 everywhere flat or very nearly so even basally and suturally, though 

 the striae become a little more distinct in the corresponding regions 

 indicated in illini. Length (c?) 16.0 mm.; width 6.0 mm. Indiana 

 (Levette collection) bispiculatus n. sp. 



Form narrower than in illini, the size smaller; surface extremely shining, 

 deep black, rather convex, the tarsi piceous; palpi obscure testaceous, 

 the antennae nearly black, becoming slightly pale near the apex; 

 head well developed, the eyes large though not quite so prominent 

 as in illini, the impressions similar but deeper and broader; labrum 

 much narrower; prothorax only about a third wider than long, 

 the sides rounded, converging posteriorly, becoming gradually very 

 distinctly sinuate, the angles nearly right and very sharp but only 

 feebly prominent; base as wide as the apex and three-fourths the 

 maximum width; surface rather convex, throughout nearly as in the 

 two preceding; elytra three-fifths longer than wide, about a fifth 

 wider than the prothorax, oblong, parallel, with feebly arcuate sides 

 and well rounded apex, the striae and intervals nearly as in illini, 

 except that the strial punctures are more distinct and that both the 

 sixth and seventh striae are subobsolete throughout the length; 

 male with the subapical tibial spine sharp though small, the apical 

 process obsolete; last ventral more broadly rounded than in illini, 

 with a finer marginal bead and with the sinus similarly very narrow 

 but extremely feeble. Length (cf) 13.7 mm.; width 4.8 mm. 

 Connecticut (Lyme), A. B. Champlain vernix n. sp. 



Possibly bispiculatus may prove to be rather a subspecies of 

 illini than a fully distinct species, but its appearance is quite dif- 

 ferent. Grams, of LeConte, is the only known species not included 

 in the above table; it is described as being black, moderately 

 shining, the elytra of the male less shining; form and, sculpture 

 as in tartaricus, except that the sides of the prothorax are simply 

 rounded, not at all sinuate near the hind angles, which are obtuse; 

 the lateral margin is rather more widely reflexed behind and the 

 length of the unique male type, which is in the Horn collection and 

 probably taken in Pennsylvania, is 19 mm. 



Diplochila Brulle. 



In my former review of this genus (Ann. N. Y. Acad., IX, p. 347), 

 the species at hand were not all correctly identified, reliance having 

 been placed too readily upon ostensibly accurate identifications in
