368 COLKOPTKRA. 



Head rather narrower than front of thorax, almost sniootli, with shallow 

 frontal impressions, labrum truncate. Eyes moderately large, slightly con- 

 vex, with fine facets. Thorax subcordate. only about a fifth broader than 

 long, base and apex subtruncate, widest just before the middle, rounded 

 there, only slightly curved and gradually narrowed anteriorly, distinctly 

 and widelv sinuate towards the rectangular posterior angles ; disc impunc- 

 tate, with fine irregular striae across it. the dorsal groove reaches the front, 

 it is somewhat expanded behind, but terminates at some distance from the 

 base ; the fossae are oblong and definite but not deep ; the lateral median 

 seta at each side is distinct, that on the hind angle small and slender. 

 P]lytra oblong-oval, twice the length of thorax, a third broader in the middle, 

 just a little wider than it is at the base, with rather broad lateral margins ; 

 their striae rather slender, deeper behind, all very finely punctured, the 

 marginal pimctation irregular ; interstices nearly jjlane, the plicae normal. 



Less robust than T. puncticollis (1799), the thorax less transverse, elytra 

 relatively longer, and the whole sculpture different. The simple thoraci(' 

 fossae, the extension of the dorsal groove to the apex, scantily pubescent 

 antennae, and unusually strong contrast in coloration of the femora and 

 tibiae prevent its being mistaken for any other described species. 



Length, 5J mm. ; breadth, nearly 2J mm. 



Ben Lomond. Unique. Found by Mr. T. Hall on the 6th March. 1914, 

 at a height of nearly 4,000 ft. 



3813. Tarastethus longulus sp. nov. 



Elongate, only slightly convex, moderately nitid ; rufo-piceous, the base, 

 suture, lateral margins, and apex of elytra and the mandibles uiore rufes- 

 cent ; legs, antennae, and palpi more or less fulvescent. 



Head narrower than thorax, nearly smooth, sometimes with a few fine 

 punctures in the rather short frontal impressions, labrum emarginate ; eyes 

 moderate, not prominent. Thorax subcordate, nearly a third broader than 

 long, widest at or just before the middle, its sides rather finely margined, 

 only moderately rounded, gradually narrowed but not sinuate behind, pos- 

 terior angles slightly prominent but not acute ; base subtruncate, only very 

 indistinctly curvate towards the sides ; apex slightly emarginate or sub- 

 truncate ; the basal region finely and moderately closely punctate, without 

 definite fossae, dorsal groove abbreviated and rather slender ; hind angles 

 without setae. Elytra oblong-oval, nearly a third broaden' in the middle 

 than the thorax, thrice its length, with the common subapical plicae ; their 

 striae regular, distinct, though rather narrow, finely punctured ; interstices 

 almost plane. 



Underside dark chestnut, trochanteis and coxae somewhat fulvescent. 

 Prosternum distinctly but irregularly punctate ; terminal segment with a 

 single setigerous apical puncture at each side of the middle. 



Though Sharp's description of the thorax of T. dehilis (1802) is appli- 

 cable to this species, that of the elytra is not, and as we are led to infer 

 that his species is of the typical short and convex form, T. longulus must 

 differ considerably. 



Length, 5-5| mm. ; breadth, nearly 2 mm. 



Clipping's Bush, near Kingston. Two found at an elevation of about 

 2,000 ft. on the 28th January, 1914, by Mr. T. Hall.
