and at the sides ; the antennae are, as is usual, shorter. P. constricticollis seems to be 

 closely allied by the shape of its thorax and the markings of the elytra to P. pruinosus, 

 Clark, but differs in the want of the elytral depression and the colour of the antennas 

 and thorax. 



10. Physimerus nigricornis. 



Dark fulvous ; antennas black ; head and thorax fulvous, clothed with yellow pubescence ; elytra brownish 

 fuscous, clothed with whitish pubescence, strongly punctate-striate, the interstices longitudinally costate. 



Length 1 line. , ■ 



Head finely and closely punctured, clothed with bright yellow pubescence ; palpi black or piceous, the penulti- 

 mate joint slightly incrassate ; antennse black or piceous, the terminal joints very slightly incrassate, the 

 joints from the third of nearly equal length ; thorax distinctly constricted at the sides below the middle, 

 obsoletely depressed across the disc at the same place, the surface punctured like the head, the punctuation 

 however scarcely visible on account of the close bright flavous pubescence, which is especially prominent 

 at the sides, the middle remaining more or less distinctly of the fulvous ground-colour ; elytra without 

 any basal elevation or depression, of a dark brownish-fuscous colour, clothed with ashy grey or whitish 

 pubescence, strongly and longitudinally costate throughout, the interspaces closely and strongly punctured ; 

 posterior tibiae with a single spur.

The costate elytra and entirely black antennas distinguish P. nigricornis, which 

 probably would have been placed by Clark in his genus Eypolampsis, a genus containing, 

 for the most part, very small species ; amongst these one or two have been named by 

 Clark E. multicostata and E. costata ; but in his descriptions he makes no mention 

 whatever of any costse which are to be found in other species of Eypolampsis. It is 

 therefore doubtful to which species the present one is most closely allied without seeing 

 all Clark's types, which I am unfortunately not enabled to do. 



11. Physimerus rubicunda. 



Testaceous below, above reddish fulvous ; head strongly and rugosely punctured ; thorax granulate-punctate ; 

 elytra closely punctate-striate, clothed with fulvous pubescence. 



Length 1 line. 



Head strongly and closely rugose at the vertex, the lower part of the face testaceous ; the penultimate joint 

 of the palpi slightly thickened ; the apices of the mandibles black ; antennae half the length of the body, 

 piceous, the two or three basal and the three apical joints obscure fulvous, the third and the three 

 following joints of equal length ; thorax very slightly broader than long, the surface rather flattened and 

 without depression, closely granulate-punctate, sparingly pubescent ; elytra scarcely visibly depressed 

 below the base, thinly clothed with fulvous pubescence, the disc closely punctate-striate, the interstices 

 obsoletely longitudinally costate ; legs testaceous or pale fulvous.
