5*74 Coleopterological Notices, V. 



both of thepe species the spines of the intermediate and posterior 

 tibiae are nearly as in lucidulus but less close-set. 



The anterior tarsi are peculiarly modified in this and possibly 

 allied species, the first four joints each having beneath a long thin 

 transparent and spatuliform appendage ; this is a common character 

 also in the American species of Pachylopus. 



ACRITU8 Lee. 



The following species belongs near Jioridae, but differs in having 

 a distinct scutellum, of which there is no trace whatever in 

 the latter: — 



A. caBlator n. sp. — Oval, moderately convex, polished, piceous-black. 

 Head finely, sparsely punctulate, more distinctly so on the large epistoma. 

 Prolhorux but little more than twice as wide as long, the sides broadly arcuate 

 and convergent from base to apex ; marginal stria very fine, continuous along: 

 the apex ; punctures fine and rather sparse, the disk with a transverse line 

 of punctures near the base, obsolete at lateral sixth, abruptly and anteriorly 

 arched in less than median third. Scutellum equilateral, small. Eltjtra a 

 little wider than the prothorax and about twice as long, evenly rounded at 

 the sides, the apex truncate, three-fifths of the maximum width ; inflexed 

 flanks with a fine strong and entire stria ; disk without trace of striae ; punc- 

 tures fine, sparse, those toward apex each with an anterior striiform prolonga- 

 tion. Propijgidium minutely, sparsely punctulate; pygidium not distinctly 

 punctulate. Prosternum nearly twice as long as its median interstrial width, 

 the striae about equally and strongly divergent toward base and apex; meta- 

 sternum large, finely, sparsely punctate, without lateral striae, the post- 

 mesocoxal plate rounded behind. Lpgs slender ; anterior tibiae not dilated. 

 Length 0.9 mm. ; width rather less than 0.7 mm. 



Indiana ? 



A single specimen from the Levette cabinet. The species differs 

 fvom floridae in its rather more narrowly oval form, and from all 

 other species most closely allied, in the strong anterior arcuation of 

 the transverse chain of pronotal punctures. In the position and 

 extent of the antennal fossae and structure of the anterior tibiae, as 

 well as prosternal and elytral structure, this genus is wholly dif- 

 ferent from Bacanius. In the latter the antennal fossa; are not at 

 all defined, the antennge being merely protected under the folded 

 legs iii the very large crural excavations. 



I have before me several specimens from the Catskill Mts., New 

 York, which seem to be referrable to cribripennis Mars. ; the elytra 

 are more inflated toward base than in exigmis, and, if the identifi- 

 cation is correct, the two forms are specifically distinct.
