40 MANDIBULATA. COLEOPTERA. 



Sp. 2. collaris. Plate III. f. 3. — Nigro-castaneus, elytris pal- 

 lidiorihus punctato-striath, ore, antennis, pedibusgiie rufis. ( Long. 

 Corp. 21 — 3 lin.) 



Ca. collaris. Herhsf. — CI. collaris. StepK Catal. No. 46. 



Closely allied to CI. Fossor, but evidently distinct^ although reputed by modern 

 continental entomologists as a simple variety of that species : it is usually 

 smaller^ and it is of a deep chesnu't-black, with the mouth, antennte, and 

 legs rufous, or pale in some specimens ; the elytra reddish-chesnut, Avith 

 the suture sometimes dusky : they are rather deeply punctate-striated, with 

 deeper impressed dots on the third stria from the suture, as in many of the 

 Carabidse : and in general this species is winged, while CI. collaris is gene- 

 rally destitute of wings, or has them merely rudimentary or imperfect. 



I have no hesitation in referring this species to the Ca. collaris 

 of Herbst, although it must be confessed his description is rather 

 laconic and general, and his figure not very good. Dr. Leach has 

 denominated it by the MSS. name of CI. sanguinea : it is not un- 

 common in hedges in many places near London, particularly in 

 Battersea fields, and on the banks of the Thames. 



Genus XIV. — Dyschirius, Pansier. 



Lahrum gibbous, obtusely rounded in front : mandibles stout, very acute, den- 

 ticulated at the base : lahium transverse, trifid : labial palpi with the terminal 

 joint nearly cylindric : antennas filiform, the basal joint stoutest, the second 

 longest: Z>orfy elongated, subcylindric : //icraa' globose : wings Wo: anterior 

 tibiw palmated externally, rarely at the tip. 



Being unable satisfactorily to determine the species of this genus 

 by experience, from their rarity near London, and having con- 

 sequently been obliged to depend upon the collation of the few 

 " dried specimens," which I possess with De Jean's CoUopieres, 

 &c. I have adopted his descriptions in preference to working them 

 anew, in order to guard against error ; and I here take the oppor- 

 tunity of remarking that from the utter impossibility of deciding, 

 with the requisite accuracy, upon the identity of other specimens of 

 minute insects, than such as I have an opportunity of thoroughly 

 examining and comparing, minutely, with tliose which are in ray 

 own possession, it is probable that more species may be at present 

 contained in collections than 1 can possibly detect.
