angulis posticis valde obtusis (fere subrotundatis), foveis 



basalibus modicis, basi latissime leviter lobata ; elytris 



striatis, striis subsuturalibus profunde (externis gradatim 



minus profunde, 5" — 8" vix vel baud manifeste) impressis, 



interstitiis sat planis (3° puncburis magnis 3 setiferis in- 



structo). Long., If 1.; lat., ^l 1. 



A Bembidiu7n-\ike species, also resembling Trechodes gihhipennis 



in facies, but with very different palpi, non-gibbous elytra, tkc. 



The basal part of the prothorax is of peculiar shape, its lateral 



portion almost continuing the line of the lateral outline of the 



segment for a short distance so that it seems to consist of a very 



wide and very short lobe.

TRECHODES (gen. nov. Trechidarum). 

 3Ientum dente acuto instructum ; ligula setifera (?); palporum 

 articulus ultimus subfiliformis quam praecedens parum 

 brevior (fere ut Perilepii)', labrum transversura ciliatum ; 

 caput supra utrinque fortiter arcuatini sulcatum : antennae 

 elongatae, articulo basali glabro ; tarsi elongati, maris anti- 

 corum articulis basalibus 2 dilatatis ; corpus convexum, 

 glabrum ; elytra (striis subsuturali et marginali exceptis) 

 baud striata. 



T. (Bemhidium) secalioides, Blackb. 



It is necessary to found a new genus for the reception of 

 Bemhidium secalioides, Blackb., which I attributed doubtfully to 

 Bemhidium (Proc. L.S., N.S.W., 1890, p. 786), remarking that 

 it might eventually have to be so treated. In spite of its 

 Bemhiditoji-like facies I find that it is in reality allied to Trechus, 

 The palpi having their apical joint elongate (as in PeriJeptus) 

 and the frontal sulci of the head being strongly arched as in 

 Trechus. Unfortunately I have not a specimen for dissf^ction, 

 so that a satisfactory examination of the ligula is not practicable 

 but I can see that it is setiferous and I think it is considerably 

 shorter than its paraglossse. The form of its palpi associate this 

 genus with Perileptus from which however its elongate tarsi, 

 strongly convex form, and very different facies, readily separate 

 it. Be?nhidiuni hipartitum, Macl., is likely to be a member of 

 this genus.
