66 MR. DATTT) SHABP OTf 



giving a minutely denticulate appearance ; eaeli granule bears a 

 hair projecting outwards. Under surface covered with obsolete 

 granules. 



This species differs from the following not only in sculp- 

 ture, but in some of the more detailed structural cbaracters. 

 The clypeus is somewhat differently formed ; it exhibits a slight 

 incrassation on each side ; th.e third joint of the antenna is not 

 twice as long as the fourth ; the eyes have fine, rather long hairs 

 in place of minute scanty scales ; and the antenual furrows are 

 deeper and rather shorter. It is allied to G. limhatus and to G. 

 rugulosus, Pasc. 



Two examples were found at Nikko. 



COLOBICUS EMAKGINATUS, var. 



Colobicus emarginatus, Latr. Gen. Crust, et Ins. ii. p. 10. 



The Japanese specimens are broader and larger than the 

 European, attaining 5 millim. in length ; the sides of the thorax 

 are more rounded, and less turned upwards, and the interstices 

 between the series of punctures on the wing-cases are broader. 



Five examples were found at Kashiwagi, in June. 



AcoLOPHUS, nov. gen. 



Corpus ovale, parvum, depressum. Tarsi antennseque debiles, hse 1 1- 

 articulatse, clava biarticulata ; oculi superne et inferne conspicui, capitis 

 sulci antennarii elongati, arguti. 



This genus need not be described at length, owing to its close 

 relationship with Golobicus, from which it differs by the elongate 

 antennary grooves which extend backwards beyond the eyes, 

 while at the front angles of the thorax there is an extremely 

 slight impression for the reception of the antennal club ; this im- 

 pression is merely a large indefinite hollow, but does not exist in 

 Golobicus. The parts of the mouth, the tarsi, and antennae are 

 much more feeble than they are in Golobicus, the trophi being 

 placed quite on the front part of the under surface of the head. 

 The metasternum is elongate, the first ventral ring quite short, 

 only about half as long as the metasternum. Under a high power 

 the eyes are seen to be studded with excessively short minute 

 asperities, which can scarcely be entitled to be called setae. 



ACOLOPHUS DEBILIS, n. Sp. 



Rufo-fuscus, opacus, parum sculpturatus, sequalisj; corpore supei'ne 

 squamulis spavsis albidis vestito, margine laterali omnium subtil issime 

 crenulato, deusissime brevissimeque albirlo squamoso. Long. 2^ millim.
