516 COLEOPTERA. 



Eleusomatus RafEray. Gen. Ins. (Wytsni.), Pselaphidae, p. 112. 



4035. Eleusomatus vidamoides sp. nov. 



Shining, indistinctly punctate ; castaneo-rufous, legs, antennae, and 

 palpi of a much lighter hue ; pubescence greyish, slender and subdepressed. 



Head as broad beliind as the middle of thorax, gradually narrowed 

 anteriorly, with obtuse hind angles, the well-marked foveac prolonged and 

 confluent in front. Eyes small and rather fiat. Thorax oviform, longer 

 than broad ; the distinct transverse groove between the rotundate lateral 

 foveae scarcely at all enlarged, not extending backwards in the middle. 

 Elytra rather broader but hardly any longer than thorax, gently narrowed 

 towards the base ; sutural striae broad and deep, at the base especially, 

 intrahumeral impressions indistinctly prolonged backwards. Hind-body as 

 broad and fully as long as elytra, only moderately narrowed posteriorly, 

 the first exposed segment with a transverse median depression at the base, 

 the following three successively diminish. 



Legs elongate. Antennae longer than those of E. ovicollis (3725), but 

 of similar structure. 



Ventral segments 2-4 diminish ; fifth shorter, truncate behind ; sixth 

 not much longer, curvedly narrowed behind. 



Of rather narrow, elongate contour, and less acuminate posteriorly than 

 other species. The head large and Vidanms-lWe in sculpture and shape ; 

 the thorax without any longitudinal groove, and the ante-basal fossa not 

 prolonged backwards. 



^. Length, quite li mm. ; breadth, fully | mm. 



Routeburn. Unique. Taken off a moss-covered tree by Mr. T. Hall 

 on the 16th February, 1914. 



4036. Eleusomatus oculatus sp. nov. 



Elongate, subfusiform, depressed, distinctly but finely jiunctate, nitid ; 

 light castaneo-fulvous, hind-body more castaneous, legs, antennae, and 

 palpi fulvescent ; pubescence subdepressed, greyish. 



In most details this closely resembles E. ovicollis (3725), but the eyes 

 are larger and more prominent, the head is broader behind and apparently 

 more contracted in front, the elytra are a third longer than the thorax : 

 the fifth ventral segment is semicircularly emarginate so that its sides clasji 

 the rotundate sixth, whereas the fifth in 3725 is truncate behind, and the 

 sixth is free and obconical. 



S. Length, 1| mm. ; breadth, nearly \ mm. 



Mistake Creek, near Mount Algidus. A single specimen obtained by Mr. 

 T. Hall along with four of E. ovicollis (all males) on the 19th October, 1913. 



4037. Eleusomatus subcaecus sp. nov. 



Elongate and narrow, subdepressed, nitid, finely and irregularly punctate ; 

 pale chestnut-red, antennae and legs fulvescent, tarsi and palpi pale yellow ; 

 pubescence greyish, decumbent, distinct. 



Head shorter than thorax, nearly as broad beliind the small eyes, 

 gradually narrowed in front of them, posterior angles obtuse ; interocular 

 foveae rather small, indistinctly prolonged forwards ; antennal tubercles 

 widely separated, somewhat elevated, smooth and shining. Thorax sub- 

 oviform, rather longer than broad, rounded and widest before the middle ; 

 ante-basal fossa angulate and extending almost to the basal margin, united 

 to the rotundate lateral foveae by the usual linear impression. Elytra
