•4193. Epitimetes densus sp. nov. 



Opaque, Euscous, legs and funiculus rufo-castaneous ; densely clothed 

 with small, flat, greyish and slightly infuscate scales, and subdepressed 

 grey setae. 



Rostrum stuut, about half the length of thorax, a little dilated in front, 

 broadly bisulcate and distinctly tricarinate. Thorax of equal length and 

 breadth, a little uneven, without obvious crests or rugae, the broad channel 

 not as deep in the middle as at the base or apex, broadly bi-impressed in 

 front, its punctation invisible ; the sides are moderately rounded and 

 slightly wider before the middle than elsewhere. Scutellum small. Elytra 

 2 A times longer than thorax, nearly a fourth broader, arcuate at the base, 

 with obtusely porrect shoulders, very slightly narrowed backwards, much 

 more so and snbvertical near the extremity ; distinctly but not coarselv 

 seriate-punctate ; third interstices obtusely elevated at the base and ending 

 as moderate horizontal nodosities, with fine grey setae, on the summit of 

 the declivity, the fifth are not distinctly raised at the base, they UK 

 similarly nodiform, but below each, behind, there is a small greyish crest r 

 the suture is broadly elevated half-way down the declivity. Antennae like 

 those of E. bkolor. 



Anterior tibiae considerably bent inwardly at the extremity, fringed 

 with tine yellow hairs and mucronate there, along the inside they are 

 distinctly tridentienlate, and slightly dilated above the middle, the other 

 pairs are moderately flexuous, the posterior without denticles. 



Underside obscure rufo-castaneous. covered with round flat scales and 

 slender grey setae, some of the former are of metallic lustre. Basal ventral 

 segment broadly impressed, the next little more than half as long and 

 obtusely angulate at the middle in front, fifth nearly as long as the basal, 

 truncate and foveate behind and with a shallow groove along the middle, 

 the supplementary lunate, concave. 



Fern. — 6£ X 2| mm. Humeral angles curvedly narrow r ed and less 

 prominent. Front tibiae less bent, not denticulate inwardly, the posterior 

 pair more minutely denticulate than the intermediate. 



<$. Length (rostrum inclusive), 6| mm. : breadth, 2 mm. 



Martinborough ; 29th October, 1916. Two males and a female, the 

 latter sent separately by Mr. A. C. O'Connor. 



Obs. — In the males of E. lutosus (763) and E. cupreus (3872) the posterior 

 tibiae on the inside, near the base, are armed with a spiniform tooth, and 

 below this are obviously ciliate : the male of E. densus therefore is mani- 

 festly different. In the other sex the hind tibiae of all the known speeies 

 are more or less denticulate only, but the front pair are simple. 



Exonastus gen. nov. 



Rostrum stout, about a fourth shorter than thorax, only slightly dilated 

 in front. Scrobes deep, quite open above near the apex, extending obliquely 

 backwards but not reaching the eyes. Thorax transverse, without definite 

 ocular lobes, base and apex truncate. Scutellum distinct, quadrate. Elytra 

 Bubcordate, abruptly broader than thorax at the base, with acuminate 

 but not prolonged apices. The duplicate cilia of posterior corbels as widely 

 separated as those of Epitimetes or Plafyomida. 



It differs from Til/ones (I'lohijilniniius) Sharp by the less pterygiate 

 rostrum and the broad external truncature <>f the posterior corbels, and 

 from Platyomida by the abbreviated scrobes, &c.
