244 Mr. H. W. Bates' supplement to the 



A Uotriopus hoplites. 



Oblongus, gracilis, castaneo-fuscus, partibus oris pedi- 

 busque castaneo-rufis ; capite fere sicut in Hypherpe, 

 angusto, seel oculis paullo magis prominentibus ; thorace 

 elongato mox pone apicem dilatato, deinde usque ad 

 basin angustato, angulis posticis obtusis sed apice denti- 

 formibus, foveis basalibus linearibus utrinque duabus, 

 profundis, lsevibus ; elytris punctulato-striatis, interstitiis 

 convexis tertio postice unipunctato, humeris exstantibus 

 dentatis ; sternis ventrisque basi utrinque valde punc- 

 tatis. 



<? . Femora postica subtus medio obtuse dentata 

 basi sinuata, trocbanteribus elongatis ; tibiae intus ser- 

 ratte. Long. 8 — 10 mm. 



Chiuzenji and Oyayama, and other places of similar 

 elevation, in rotten trees or under old timber. 



Belongs to the genus Allotriopiis, of which only one 

 species has yet been described, from Mexico. It differs 

 from the Mexican species in the hind tibiae being straight, 

 not bowed, and in the femora being dilated and toothed 

 beneath in the male. AUotriopus agrees with Pterostichus 

 in its short metathoracic episterna. 



Hypherpes colonus. 



H. castanipedi affinis, sed magis linearis. Elongatus, 

 angustus, nigro-piceus, antennis palpis et pedibus rufo- 

 castaneis ; capite angusto, post oculos paullulum promi- 

 nentes gradatim angustato ; thorace elytris angustiori 

 elongato-ovato, sat convexo, prope basin angustato ibique 

 lateribus rectis, angulis posticis subacutis, fovea basali 

 utrinque oblonga, profunda punctata ; elytris punctato- 

 striatis, interstitiis sat convexis, striola scutellari obsoleta 

 ibique puncto ocellato; sternis utrinque grosse punctatis, 

 episterno metathoracico curto sed angusto ; femoribus 

 validis. Long 12 mm., S . 



Oyayama ; one example from an old beech in April. 



Belongs to Hypherpes by the absence of punctures 

 from the 3rd elytral interstice. It is also not unlike in 

 facies the narrower and more convex sj>ecies of the 

 genus, e. g., H. castanipes, differing in the relatively 

 longer and more convex thorax.
