(S. Length (rostrum exclusive), 4 mm. ; breadth, quite 1| mm.

3929. Eugnomus bryobius sp. nuv. Exgnoimis Sclioenherr, Lacord, Hist. 



des Ins. Col., Tom 6, p. 500. 



Robust, moderately convex, opaque, variegate ; usually rufo-castaneous, 

 Avith a large fuscous space, sometimes reaching the suture, at or just before 

 the posterior femora, thoracic disc darker than the sides, club and terminal 

 joints of tarsi nigrescent, the scape more rufescent than funiculus; squa- 

 mosity depressed, somewhat oviform, flavescent and slender on the rostrum 

 and thoracic disc, sometimes griseous on the elytra, and in some examples 

 mingled with short slender setae. 



Kostrum moderately arched, a little expanded in front, rather longer 

 than thorax, coarsely punctate, apex nearly smooth and shining, with an 

 elongate interantennal fovea. Eyes prominent, subrotundate, the space 

 between them and the thorax rather less than their own length, with a 

 well-marked depression between them above. Thorax evidently constricted 

 in front, a little broader than long, base and apex truncate, its sides nearly 

 straight behind ; closely and moderately coarsely punctured, the squamae 

 at the sides rotundate and paler than those on the disc. Scutellum oblong. 

 Elytra somewhat biarcuate at the base, about double the width of thorax 

 there, more than thrice its length, considerably narrowed behind, with 

 singly rounded apices ; they are moderately finely and closely punctate- 

 striate, with the suture and 3rd and 5th interstices more or less obtusely 

 elevated. Pygidium exposed, finely punctate, subquadrate or elongate- 

 obconical. 



Legs moderately elongate ; femora clavate and obtusely angulate but 

 not dentiform underneath. Scape slightly flexuous, attaining the middle 

 of the eye. Funiculus 7-articulate, basal joint thicker and slightly longer 

 than elongate 2nd, joints 3-7 gradually diminish, none, however, are trans- 

 verse or moniliform. Club elongate-oval, its 1st joint narrowed towards 

 the base and much longer than the next, 3rd also elongate. 



Underside slightly convex, thickly covered with elongate grey squamae, 

 more slender and filiform on the 5th abdominal segment, which has a 

 rotundate apical fovea. Mesosternal process quadrate between the middle 

 coxae, truncate or sHghtly emarginate behind. 



Scrobes subapical, not definitely prolonged below. 



Readily distinguishable by the robust form, obtusely elevated suture 

 and alternate elytral interstices, differently formed femora, &c. 



Length (rostriim exclusive), 5-5| mm. ; breadth, 2-2^ mm. 



Moa Basin. Numerous specimens found living in moss on the banks 

 of the stream, by Mr. T. Hall, on the 20th October, 1913. There is a con- 

 siderable amount of variation amongst the individuals, but I fail to detect 

 true specific differences. 



3930. Eugnomus alternans sp. no v. 



Subdepressed, rather short and broad, opaque ; fuscous, head and 

 rostrum, the elytral suture, and the club piceous, scape and legs castaneous ; 

 irregularly clothed with depressed, greyish, elongate, setiform squamae. 



Rostrun\ only feebly arched, parallel, slightly longer than thorax, rather 

 finely punctate, subcariiuite along the niiddle. smooth at apex, witli an
