368 COLEOPTERA. 
Head rather narrower than front of thorax, almost smooth, 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 widely sinuate towards the rectangular posterior angles ; dise impune- 
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. 
Elytra 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 punctation irregular ; interstices nearly plane, the plicae normal. 
Less robust than 7. puncticollis (1799), the thorax less transverse, elytra 
relatively longer, and the whole sculpture different. The simple thoracic 
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, 54 mm.; breadth, nearly 2} 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 more 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 shghtly 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 broader 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, trochanters 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 7. debilis (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, 7. 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.
