130 GEO. II. HORN, M. D. 



emarccinato. Mandibles slislitly prominent, arcuate, acute at tip. inner edge feebly 

 tiiurlii'd .-it iniildle, outer Iowit edge slightly expanded, the outer (ace concave and 

 uiili a di-iinct seiigeriiiis puncture. Maxillie ^Jtout, with a double row of short 

 stilt' spines within, ])alpi stout, teriuiual joint slightly fusiform and obtuse at tip. 

 Mentuui broad, deeply emarginate without tooth, basal suture distinct. Ligula 

 short, broad, aciute and bisetose at tip, the paraglossse slender slightly longer than 

 it and ciliate within at tip, palpi short, last joint slightly fusiform, obtuse at tip. 

 Thorax with two setae near the front angles and one at the posterior. Body 

 pedunculate, scutellum not visible between the elytra. Elytra slightly margined 

 at base near the hind angles, sides very narrowly inflexed, margin slightly 

 interrupted posteriorly and with a short internal plica, no dorsal punctures. 

 Prosternum obtuse, not prolonged at tip. Mesosternum oblique the coxse sepa- 

 rated, epiinera and episterna nearly equal. Posterior coxae contiguous. Abdomen 

 with posterior margins of segments 3 — 4—5 narrowly coriaceous. Legs moderate, 

 middle and posterior tibife ciliate externally, the anterior slightly broader at 

 tip, emarginate within, tlie spurs distant. Tarsi not dilated. Sexual characters 

 as in Scarites. 



As far as I can ascertain this tribe is represented by a single genus 

 Nomiua^ (Haplochile Lee), the position of which has been the cause 

 of differences of opinion. For Dejean, Duval and Schaum it was a 

 Morionide, Lacordaire (not knowing Haplochile), places Nomius in the 

 Ozenides and Haplochile in Morionides. Chaudoir properly omits it 

 from his essay on the Ozenides, while Bedel (Ann. Fr. 1879, suppl. 

 pp. 24 and 42), places it in his tribe Bembidiini which is part of a very 

 heterogeneous and impossible sub-family Bembidiidas. Under Psi/drus 

 will be found its history in our fauna. 



From the Morionini it differs in the form of the anterior tibite and 

 mesosternal epimera and the presence of a mandibular setigerous punc- 

 ture, the form of the ligula and paraglossoe and the structure of the 

 abdomen. 



The mesosternum is not narrow between the coxa3 but emarginate, 

 receiving the metasternum and in this- respect differs greatly from the 

 Ozaenini which have the mesosternum, at most, linear between the coxae 

 and never wide enough at tip to be emarginate. 



I cannot understand why Bedel is willing to place Nomius near 

 Bembidium, Patrobus, etc., the only point in which it resembles these 

 is in the presence of mandibular seta. Its affinities seem to me to be 

 best indicated by placing it between the Ozaenini and the Morionini. 



Nomius contains but one species N pi/fjmseus Dej., which occurs in 

 various parts of southern Europe, and in many places in our country 

 from Georgia to California. 



It occurs under stones, etc., in moist places, and exhales a strong- 

 fetid odor. 



To this tribe two anomalous foreign genera should be referred Mc/prniis
