Mount Piiongia, December 1909. 1 fouiiJ a s-in-lc male 

 only. 



337S. Euplectcpsis mucronellas, sp. n. 



Elongate, moderately narrow, slightly convex, shinino; , 

 castanco-rufous, tarsi and ])alpi t'ulvescent ; the clothing 

 greyish, rather short, and thinly distributed. 



I/tad much smaller than the thorax, nearly straight behind 

 the rather small and hardly at all prominent eyt-s, sligiitly 

 narrowed anteriorly, antennal tubercles somewhat flattened 

 backwards; the fovese not sharply detined, prolonged and 

 convergent in front ; there are no perceptible punctures. 

 Thorax suboviform, rather longer than broad, gently rounded 

 and slightly broader before the middle; dorsal sulcus narrow, 

 extending from before the middle to the moderately deep 

 but not broad semicircular basal fossa; lateral fovete deep, 

 subrotundate, rather large, but not distinctly prolonged 

 anteriorly, the antebasal transverse impression normal. 

 Elytra a third longer than the thorax, oblong, only slightly 

 narrowed near the base ; sutural striie deep, punctiform at 

 the base, with a distinct basal puncture alongside each ; dorsal 

 impressions rather short, broad, and deep at the base, hind 

 budy almost tis broad as but rather shorter than the elytra, its 

 basal three segments equal. 



Leys elongate and moderately slender, the intermediate 

 tibiie gently aiched externally and minutely prominent at the 

 inner extremity. 



Anteiince shorter than the head and thorax, moderately 

 sKnder, their second joint fully as lung as the visible portion 

 of the thicker basal one; third smaller, rather longer than 

 broad, gradually narrowed towards its base ; joints 4-8 

 small, each about as long as broad, seventh very slightly 

 longer; ninth subquadrate, a little larger than preceding 

 ones ; tenth transverse, moniliform, but little broader than 

 ninth ; the terminal conical and acuminate, as long as the 

 preceding two united. 



Underside chestnut-red, with grey pubescence. Meta- 

 sternum unimpressed. Ventral segments 2-4 equal, fifth 

 widely incurved, not quite as long as the fourth in tlie middle, 

 sixth more deeply incurved, seventh broad, as long as the 

 penultimate. 



After a careful comparison with Reitter's types, I fail to 

 find one that accords with this species ; the nearest, but only 

 so far as the middle tibiae are concerned, is E. microcepkalus.
