Species of PselaplnJ£e//-o?« New Zealand. 691 



median angular prominence; fourth and fifth very sliort in 

 the middle, together shorter than the third ; sixth sliglitly 

 longer than fifth, widely yet slightly incurved, seventh rather 

 longer, transverse, rounded. 



Female. — Basal dorsal segment similarly impressed; 

 second ventral segment slightly longer than third, the next 

 two, singly, a little shorter than the third ; sixth curvi- 

 linearly triangular, about as long as the preceding two 

 combined. 



The form and sculpture of the head and thorax, the elon- 

 gate and very acuminate terminal joint of the antennae, in 

 conjunction with the remarkable second and third ventral 

 segments of the male, distinguish this species. It is entirely 

 different from the more cylindrical series, such as E. par- 

 vulus, 2727, and Reitter's E. microcephalus. It must be 

 placed at the end of the genus, as the deep thoracic sculpture 

 closely resembles that of Raffray^s Plectomorphus. 



Length If; breadth nearly f mm. 



Erua, January 1910 ; Waimarino, and also found amongst 

 leaf-mould sent to me from Makatote by Mr. W. S. Guinness. 



About a dozen specimens of this somewhat variable species. 



ViDAMUS, Raflfray.

3380. Vidamus trochanter alis, sp. n. 



Shining, castaneo-rufous, sometimes much paler, antennay 

 and legs fulvescent; the clothing rather elongate and con- 

 spicuous on the hinder parts, and mingled with a few erect 

 slender setfe. 



Head large, a 'good deal rounded behind the prominent 

 eyes, not definitely punctate ; the fovete large but not very 

 deep, on about the same plane and continuous with the de- 

 pressed frontal portion. Thorax hardly wider than the head 

 at or just before the middle, much narrowed anteriorly, a 

 little longer than broad, the disc smooth ; basal median fossa 

 somewhat angulate, the transversal linear impression between 

 it and the large lateral fovese sometimes indistinct, the basal 

 margin indistinctly tripunctate. Elytra about as long as 

 broad, wider than thorax at the base, still more so behind, 

 and obviously longer than that is ; sutural strise well marked 

 throughout and punctiform at the base, intrahumeral strise 

 deep but short ; between these striae on each elytron there is 

 a distinct basal puncture. Hind body rather narrower than 

 the elytra, the basal visible three segments almost equal.
