Leucohimatium beete, n. sp. 



L. elongato-ovatum, angustulum, rufo-ferrugineum, hreviter suhalhido-puhcscens ; 

 eapite froihoraceque opacis, coriaceo-alutaceis {nee punctatis), illo triangularis oculis 

 maximis prominentibus, hoc sub-quadrato , ad latera (mimite crenulata) et postice 

 (retrorsum producto) incrassato-marginato, angulis anticis rotundatis, posticis argute 

 obtusis, postice in medio obsolete gibboso-carinato : elytris (pone medium gradatim 

 suh-latioribus) leviter punctato-striatis, ad latera sub-grosse marginatis, et ad apicem 

 obscure desilienti-terminatis. Long. corp. lin. 1. 



As compared with tlie European and Atlantic L. clongatum, tlio 

 present species is very niucli smaller, as well as relatively shorter and 

 less parallel (its outline being elongate-ovate, rather than linear) ; 

 its surface is darker, or more ferruginous, and less densely covered 

 with silvery pubescence ; its eyes are more prominent ; and its head 

 and prothorax are alutaceous and opaque, instead of shining and 

 punctured. The latter, moreover, which is free from the two basal 

 fovea>, has the anterior angles (although rounded off) destitute of any 

 appreciable tliicJcening, and the sides (which are obsoletely creuulated) 

 less straightened ; and the central region behind is very obsoletely 

 keeled. The elytra, also, which are considerably margined, arc some- 

 what suddenly desilient at their apex. 



Pam. MTCETOPHAGIDJE. 

 Genus TeiphYLLUS, Latreille, Ecgne Anim. v. 98 (1829). 



Two examples of an insect now before me, which were taken by 

 Mr. Lewis in Japan, are, I think, unquestionably Triphylli ; though 

 their general aspect and coloration are, at first sight, strongly sug- 

 gestive of the European Tetratoma ancora. Nevertheless, they are in 

 reality altogether distinct from the latter, — their 3-jointed club, added 

 to the structure of their feet (the four hinder ones of which are 

 quadri-articulate, while the front pair have but three joints), assigning 

 them, apart from every other character, to the Mycetophagidce. The 

 species in question, which appears (judging from the diagnosis) to be 

 totally distinct from the T. himaculatus of Montrouzier, from New 

 Caledonia, may be briefly characterized as follows : 



Triputllus Lewisianus, n. sp. 

 T. oblongus, sub-nitidus, piibescens, ubique profunda sed vix dense punctatus, rufo- 

 tettaceus ; prothorace (transverso, convexo) in disco 'plus minus obscuriore, utrinque 

 ad basin fovea punctifonni iiyiprcsso ; elytris fascid media transversa sub-dentatS, 

 nigrd ornatis ; antcnnis versus apicem gradatim paulu obscuratis.
