4248. Somatidia origana sp. nov. 



Elongate, moderately convex, subopaque ; rather thinly covered with 

 decumbent, greyish, rather short and slender hairs ; castaneo-rufous, the 

 head, a broad space on each side of the thorax from before the middle and 

 nearly touching the other at the base, a large basal s2><-*t on each elytron 

 from the side to the middle, and a few lateral spots near the apex, are 

 nigrescent; legs testaceous, tibiae slightly rufescent above, the subapical 

 spot blackish ; antennae unspotted 



Head and eyes hardly as broad as thorax vertex coarsely punctate and 

 slightly uneven, the forehead not flattened, broadly but shghtly convex 

 along the middle. Thorax of equal length and breadth, obtusely rounded 

 and widest before the middle, more gradually narrowed behind than in 

 front ; irregularly, moderately coarsely but not closely punctate. Scutel- 

 lum very small. Elytra elongate-oval, of the same width as thorax at the 

 base, about a fourth broader than it is at the middle, twice its length ; they 

 are without crests, but on each of the dark basal areas there is a short 

 iongitudinal elevation ; their punctation near the base is as coarse as that 

 of the thorax, it becomes finer behind and almost ceases at the extremity, 

 it is not quite seriate, and is more distant than that of the thorax. 



Antennae stout, with fine greyish pubescence and some rather longer 

 hairs ; they just pass the hind thighs, their third joint barely reaches the 

 thoracic ba^e, the fourth is slightly longer than fifth, tenth shorter than 

 eleventh. 



The nearest species, S. flavidorsis (3947), has a fine groove along the 

 head, the punctation is more distant and finer, and almost seriate on the 

 elytra ; the antennae, coloration, and other details also dift'er. 



Length, 4-| mm. ; breadth, 1| mm. 



Mount St. Arnaud, Nelson. My specimen was caught by Mr. T. Hall 

 on the 15th June, 1916. 



4249. Somatidia oedemera sp. nov. 



Robust, convex, oblong, medially depressed and narrowed, without 

 crests or superficial inequalities, somewhat shining ; cupreo-fuscous, antennae 

 and femora rufo-fuscous, tibiae and tarsi paler ; pubescence greyish, unevenly 

 distributed, mingled with longer suberect hairs. 



Head about half the width of thorax, minutely and densely punctate 

 and with some larger punctures and a fine stria along the middle. Thorax 

 large, slightly broader than long, widest and rounded near the front, a good 

 deal narrowed and depressed behind ; irregularly and moderately coarsely 

 ])unctured, more closely in front than on the middle. Scutellum small, 

 triangular. Elytra of the same width as thorax at the base, hardly twice 

 its length, widest behind the posterior femora, strongly curvedly deflexed 

 behind ; their punctation subseriate alongside the suture, more distant and 

 finer than that of the thorax. 



Femora slender near the base, veiy strongly clavate beyond ; tibiae 

 stout, only slightly infuscate above ; anterior tarsi rather broad, basal 

 joint dilated and cordat<'. 



Antennae finely pubescent, immaculate, not quite the length of the body ; 

 third joint hardly reaching tlioracic base, fourtli and fifth subequal, longer 

 than following ones. 



Underside rufo-fuscous, abdomen darker but with a brassy tinge. 

 Prosternal process nearly plane, that of the mesosternum subparallel. 

 Basal ventral segment as long as the following three combined ; fifth longer
