248 LECONTE— SYNOPSIS OF PTEROSTICHUS. 



Georgia, rare. Wider than tiie 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 punctato, elytris tripunctatis, 

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



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



Southern States, not rare. 



44. P. p e r m u n d u s , nitidissimus, cyaneo-micans, thoracis margine et basi punctato, elytris tripunctatis, 

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



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



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

 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 ; parapleurse elongatae ; abdomen articulo l""" non inipresso ; elytra punctis 



dorsalibus tribus, striaque scutellari notata ; tarsi posteriores extus non suleati, 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 defined, 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.
