iutei'coxal projection of the liiiid-body wide, but not cxecBsively so. The 

 position of the eyes (placed entirely above a lateral line imagined as 

 bisecting the head and rostrum longitudinally, and looking upwards) 

 gives the insect a singular appearance, the eyes in their entirety being 

 visible from above. 



A. iioxTANUS, sp. n. 



Rufo-piceiis, aneo-niiens, anteitnis pedihusque obscure rtifis ; rostro lato, sub- 

 depresso, capite longiore, sparsim subtiUter punctata ; antennarum funiculi articulo 

 secundo primo lonffiore angustioreque ; thorace elongato, lateribus parum rotundatis, 

 antice fortiter, postice leviter, contracto, fortiter sat crebre punctato ; coleopieris 

 ovatis, parum convexis, striatis,striis fortiter punctatis ; interstitiis leviter convexis^ 

 crebre punctut is. Long. 5J — G\ mm. 



This singular insect occurs in bark, in forests on the mountains 

 of Oahu. As yet I have met with it but rarely. 



OODEMAS HALTICOIDES, Sp. n. 



Augustus, ceneo-virescens, nitidissimus, antennis genubus tarsisque rufis ; rostro 

 capite longiore, lato, rugoso-punctato ; capite subtilissime punctato ; antennis brevibiis 

 crassiuscuHs,fimiculo articuli secundo primo longiore ; thorace elongato, antrorsum 

 modice contracto, coleopteris parum angustiore, siibtiliter nee crebre punctato; coleop- 

 ieris oblong is, prof unde seriatim punctatis, interstitiis vage subtiliter punctatis. 



Long. 4—5 mm. 



Very distinct from O. cenescens, Bohem. (which is not uncommon 

 here). It is smaller and very much naiTOwer ; the rostrum is shorter, 

 broader, and much more strongly punctate ; the antennse are thicker, 

 with the scape shorter and much more strongly clubbed ; the basal 

 joints of the funiculus, too, are differently jjroportioned (the 1st joint 

 being about as broad as long) ; the elytra are not striated. The 

 superficial resemblance of this insect to a Halt lea (shared by its 

 congener) is most striking. It has occurred to me (rarely as yet) in 

 bark, in forests on the Oahu mountains.

DESCRIPTION OF A NEW SPECIES OF BUTTERFLY FROM 

 LAKE NYASSA. 



BY W. C. UEWITSON, F.L.S. 



Mr. Simons, who went out with Lieut. Young's expedition to 

 Lake Nyassa, has sent home a few butterflies, the proceeds of a 

 month's collecting ; but as they had been picked at the British 

 Museum before reaching mc, I have no idea of the original wealth of
