290 COLEOPTERA 



Lomemus. 



Sharp; Ann. Mag. Nat. Hist., May, 1877. 



The exponents of this genus show characters to a considerable 

 extent similar to those of Aglophus modestus ; the head is almost simi- 

 larly formed ; the antenna, however, are always more or less serrate ; 

 the thorax is more elongate, the prosternal sutures are narrowly open in 

 their anterior part and are not sinuate in front ; the prosternal process 

 is short, and is bent up in Lomemus pilicornis, but is longer and nearly 

 straight in L. obscuripes ; the intercoxal space is narrow, and the meso- 

 sternal cavity is narrow, ill-limited behind, its posterior extremity very 

 far from the intercoxal suture ; the space separating these two parts is 

 longitudinally grooved. The femoral portion of the coxal plate is short, 

 the trochanteral portion moderately long ; the fourth joint of the tarsus 

 is minute, the third simple or obscurely emarginate at the extremity. 

 Species of small size. 



I have had so few examples of these small species at my disposal 

 that I cannot deal in a full and satisfactory manner with their structural 

 details ; and it is probable that a thorough examination would show that 

 I have left together in one group species which may ultimately form 

 several distinct groups ; they may, however, be distinguished from the 

 species of Aglophus by the different prosternal sutures, by the less 

 diminished femoral portion of the hind coxal plate, and the less developed 

 third and fourth joints of the tarsi. 



509. L. piliCOrniS, Sharp; Ann. Mag. Nat. Hist., May, 1877. 

 L. angustulus, minus nitidus, evidenter pubescent, niger, prothoracis 

 angulis posterioribus pedibusque testaceis ; tibiis versus apicem fuscis ; 

 antennis elongatis, tenuibus, sed intus serratis, longius pilosellis, articulis 

 secundo et tertio brevissimis, quam quartus conjunctim multo breviori- 

 bus ; prothorace antrorsum angustato, crebre fortiter punctate, sat elon- 

 gate, angulis posterioribus subuncatis ; elytris striatis, striis punctatis, 

 apice summo obsoletis, interstitiis punctatis. 



Long., 5 mm. 



The pilose antennae, the black colour, with yellow legs and hind 

 angles of the thorax, very readily distinguish this species. 



Three specimens have been cut out of a tree-stump at Tairua by 

 Captain Broun ; two of them he sent me.
