984 COLEOPTERA 



but obsoletely punctate, and are obsolete at the sides and apex. 

 The legs are black, the tarsi pitchy-red. 



New Zealand. Castelnau ; a single example. This insect has, 

 perhaps, more the facies of Adelinni aucklandicum, Broun one of 

 the Heteromera than of any New Zealand Carabidce. 



Ctenognathus. 



(Fairmaire; Ann. Soc. Entom. France, 1843.) 

 This genus includes such species of Anchomenidce as possess only 

 one tactile seta on each side of the thorax, placed in front of the 

 middle. This character is substituted for Fairmaire's by Dr. Sharp. 



1771. C. munroi, n.s. Robust, broad, not depressed, shining- 

 black ; tarsi and palpi pitchy-red ; the basal four articulations of 

 antennae piceous, the others pale fusco-rufous. 



Head oviform, nearly smooth ; eyes prominent ; labrum truncate, 

 or nearly so. Thorax very little broader than long, almost regularly 

 rounded laterally, but, though narrowed, nearly straight behind the 

 middle, posterior angles obtuse ; base and apex truncate ; lateral 

 margins distinct and somewhat reflexed, not angulated medially ; 

 disc almost convex, basal depressions large, prolonged forwards to 

 beyond the middle, yet separated from the marginal channels; dorsal 

 groove well marked, furcate near the front. Scutellum triangular, 

 smooth. Elytra oviform, broader than thorax, widest before the 

 middle, narrowed and sinuated apically ; apices, conjointly, with a 

 sutural, almost semicircular, excision ; humeral angles rounded ; 

 they are somewhat convex, especially the suture, which is raised, 

 and appears smooth and shining as compared with the finely 

 shagreened and rather dull but silky-looking surface, this smooth 

 sutural space widened in front and there impressed with a short 

 groove or row of punctures ; they are distinctly striate, with regular 

 punctures in the striae, interstices without punctures. 



Underside glossy, pitchy-black ; both sexes with two faint seti- 

 gerous punctures near the apex of the last ventral segment. 



Male. Tarsi estriate, or with only very feebly-marked impres- 

 sions on the anterior. 



Its nearest ally is undoubtedly No. 1455, but in that species the 

 elytral apices are much narrower and more prolonged ; the thorax 

 is shorter, broader, incurved in front, transversely strigose, and its 

 basal angles are more rounded ; the labrum is emarginate. 



<, ? . Length, 7-7f lines; breadth, 2| lines. 



Clevedon, South ; Wairoa. The name of its discoverer, Mr. George 

 Munro, has been applied to this fine species. 



45. C. latipennis (new name). (Anchomenus elevatus, Bates; 

 Ann. Nat. Hist., xiii., p. 10 (reprint), nee White. Sharp; Trans. 

 Roy. Dub. Soc., Nov., 1886, p. 363.) Robustus, latior, niger, antennis 

 palpisque runs, pedibus piceis ; prothorace lato angulis posterioribus 

 perobtusis ; elytris profunde stnatis, striis haud punctatis, interstitio 

 secundo puncto unico versus apicem sito.
