248 LECONTE— SYNOPSIS OF PTEROSTICHUS. 



Georgia, rare. Wider than the two following species, less shining, and scarcely 

 iridescent ; the pectus is punctured, but the abdomen is smooth. 



43. P. sculptus, nitidissimus, cyaneo-micans, thoracis basi et margine punctate-, elytris tripunctatis, 

 profunde striatis, interstitiis convexis, abdominis lateribus punctatis. Long. -55 — -7. 



*Feronia {Abax) striata\\ Dej. Sp. Gen. 3, 390. 



Southern States, not rare. 



44. P. permundus, nitidissimus, cyaneo-micans, thoracis margine et basi punctato, elytris tripunctatis, 

 striis profundis punctulatis, interstitiis convexis, abdominis lateribus punctatis. Long. '6. 



Abax permundus Say, Trans. Am. Phil. Soc. 4, 426. 



Missouri and Illinois. This must be Say's species, although he described the striaB 

 of the elytra as impunctured ; the punctures are very small but distinctly visible 

 with a powerful lens. It is closely allied to the preceding species but is narrower 

 and more parallel. 



LOPHOGLOSSUS Lee. 



Antennae tenues, basi non carinatae ; palpi cylindrici, articulo ultimo vix breviore ; mentum dente medio 

 concavo et emarginato, ligula carinata apice subemarginata, paraglossis elongatis, linearibus ; labrum 

 leviter emarginatum ; parapleuree elongatas ; abdomen articulo l mo non inipresso ; elytra punctis 

 dorsalibus tribus, striaque scutellari notata ; tarsi posteriores extus non sulcati, anteriores maris 

 articulis 3 obcordatis, emarginatis ; tibiis intermediis maris intus versus apicem emarginatis et 

 bidentatis. 



This genus only differs from Pterostichus in the form of the ligula, and I have some 

 doubts whether it should really be separated ; but in order to leave the limits of the 

 preceding genus distinctly denned, it will be necessary to retain this as a generic 

 group, since it has no trace of a groove on the outer margin of the four posterior tarsi. 

 This genus in part corresponds to Chaudoir's Lyperus. 



The three species below described correspond in the following particulars. The 

 head is large, the eyes prominent. The thorax subtransverse, narrowed behind, a 

 little rounded on the sides, which have a strongly reflexed margin gradually 

 becoming wider behind ; anterior transverse line deep, distant from the margin ; the 

 basal angles obtuse, not rounded, the basal impressions deep and single; the elytra 

 are flattened, little wider than the thorax, deeply striate, the striae a little less deep at 

 the apex ; the margin is narrow, and the ninth stria is equidistant between the series 

 of punctures and the margin ; the humeral angles are distinct and rounded. The 

 body is oblong and winged. 



1. L. Haldemani, depressus, elytris tripunctatis, opacis, tenuiter striatis, interstitiis subconvexis, 

 pectore toto punctulato. Long. -87. 

 Lyperus Haldemanni LeConte, An. Lye. 4, 341. 



One female from Alabama, Haldeman. Distinguished from the following by its 

 opake elytra with much finer striae.
