COLEOPTERA 50 r 



not stout, approaching- somewhat to the slender condition found in N. Jilipcs. The 

 lobes of the third tarsal joint are however not reduced as they are in N . filipes (see 

 PI. XVI. fiL;-. 7, for comparison with N. filipes). Female pygidium short, apically 

 broad and subtruncate with rounded angles. Eight specimens. 



This very distinct species has a prosternal process projecting distinctly behind the 

 co.xae, and not at all curved upwards at its termination.

(19) N'e so pet hi Its filipes, sp. nov. 



Subdepressus, parcius, pubescens, sat nitidus, pallide testaceus, abdomine nigro- 

 fusco, apice testaceo, prosterno mesoternoque fuscescentibus ; elytris subseriatim minus 

 subtiliter punctatis. Long. i\, lat. \\ mm. 



A very peculiar species. Head small, antennae short, pale yellow. Thorax trans- 

 verse, the sides narrowed behind, with a narrow definite explanation, the hind angles 

 obtuse, the punctuation coarse. Elytra broader than the thorax and with punctuation 

 almost similar. Legs slender ; femora projecting distinctly beyond the sides of the 

 body; lobes of tarsal joints, especially those of the third joint, small (see PI. XVI. 

 fig. 6, for comparison with foot of N. concolor). Male pygidium shallowly emargi- 

 nate or only sinuate apically, the angles rounded and blunt : supplementary segment very 

 characteristic, narrow, very tapering, rounded and without any depression or emargi- 

 nation apically. Female pygidium rather broad at the base, tapering, narrow and 

 rounded apically. 



Though very distinct as a species, this is one of the most difficult to classify. The 

 prosternal process is short, and is convex between the co.xae, but behind them it is but 

 little directed upwards, and the species is therefore better placed in Nesopetimis than 

 in Nesopepliis. 



We have i 5 specimens, mostly males.

Brachypeplus quadratieollis Blackburn, Tr. Dublin Soc. iii. 1885, p. 135. 



Nigricans, supra inauratus, rufo-variegatus, antennis pedlbusque rufis ; [irothorace 

 parum transverso, dense punctato, laterlbus subrectis anterius angustatis, basl tere recte 

 truncata angulis posterioribus rectis. Long. 4, lat. \\ mm. 



This appears to be a very distinct .species, approximating by the form ot the 

 thorax somewhat to the Nesopelitins blackhiirni allies ; the pronotum too is applied to 

 the elytra in a somewhat similar manner. The structure of the prosternum agrees with 

 Nesopetinns scottianus. The species appears to be \'ery rare ; we have six specimens.
