described, tlie validity of tlie genus must be admitted. M. Lethiei'ry, 

 of Lille, lias had tbe goodness to send me an example of iV. limhatus, 

 Avliicli agrees exactly with. Pieber's description. Our insect is iden- 

 tical, except tbat in it tbe second joint of the antennae is black, and 

 rusty-yellow only at the extreme base ; whereas, in his, the lower half 

 of the second joint is rusty -yellow ; but, although this coloration ap- 

 pears to be a constant character in French examples, yet, as ours differs 

 only in this respect, I am obliged to consider it as only a variety of 

 N. litnhatus. 



M. Lethierry says (Cat., p. 20) that he finds the species in April, 

 sometimes rather commonly, but only in one locality in a wood, near 

 a sand-pit, by sifting moss, under which are several nests of three 

 species of ants, Ponera contracta, Myrmecina Latreillei, and Formica 

 inifa ; he also once obtained several examples in the interior of the 

 nests of the last.

 (Megalonotus, Fieb.) 



ElIYPAEOCHEOMUS SABTJLICOLA. 



Li/r/<sit,s sahulicola, Thoms., Opusc. Ent., ii, 190, 23 (1870). 

 Megalonotus sahulicola, Leth., Cat., 2nd edit., 15 (1874). 

 Black, clothed with golden pubescence. 



Head in front and before the eyes with long projecting hairs. ^«^e««<E short, black, 

 1st joint at tlie apex, 2nd and 3rd except the apex, rnfous. Pronotum slightly, 

 but posteriorly coarsely, punctured, the sides with long projecting hairs. Ulylra — 

 corium light brown, posteriorly with a black blotch, in wliich arc two pale spots, 

 the disc clothed with short, sub-depressed, black hairs, and having black punc- 

 tures in distant rows ; membrane pale fuscous, a distinct yellowish spot at the 

 inner basal angle, and a small one at the outer angle ; nerves broadly whitish in 

 the middle ; or the membrane is abbreviated, fuscous, with a pale spot under the 

 apex of the corium and indications of pale nerves. Xeys — thighs black, the 

 extreme apex of all, the basal third of the 2ud and 3rd pairs, t\\e fulcra, all the 

 tih'ice wholly (except sometimes the 1st pair at the extreme apex), the Ist and 

 2nd joints of the tarsi, and the claws, rufous. 



Under-side clothed with delicate, silvery pubescence. Length, If- 2 lines. 



This species, as M. Lethierry says (I. c), has doubtless been con- 

 founded with R. chiragrn, Fab. It is distinguished from the latter by its 

 much smaller size, by the shortness, positive and relative, of the antennjr, 

 by the redness of the 3rd as well as of the 2nd joint thereof, by the 

 slighter puncturing of the posterior portion of the pronotum, by the 

 base of the 2nd and 3rd pairs of thighs being broadly red, and by the 

 redness throughout of all the tibioe. 



I have two specimens taken on the sand-hills at Deal, one in May, 

 the other in ISeptcmber, 1872.
