Longicornia Malayana. 41 



on the prothorax, which assinne, under an ordinary glass, the form 

 of hnes, another and broader patch on each side ; elytra also ap- 

 parently lined in the same way, but with more grey at the sides, 

 leaving, however, at about the middle a large well-defined reddish- 

 brown patch, another such patch posteriorly, and between the 

 suture and the first-mentioned patch an oblong line gradually 

 spreading out posteriorly; body beneath chesnut-brown, the first 

 abdominal segment paler ; tips of the tibiae and tarsi dark brown ; 

 antennae more than half as long again as the body, luteous-brown. 

 Length 3 lines. 



Mgoc'idnus jubatus. 



M. griseo-brunneus ; prothorace linea longitudinal! in medio 

 griseo-hirta ; oculis brunneis. 



Hab.- — Macassar. 



Ihis species closely resembles the last and may be only a local 

 variety, but the central line of the prothorax is strongly marked 

 and the lateral patches are less so ; the elytra, except the patch at 

 the side, are nearly unicolorous, or only slightly mottled from 

 abrasion, and the eyes are light reddish-brown. 



Length 3 lines, 



JEgocidnus ignarus. 



M, brunneus ; prothorace breviore, medio griseo-sublineato ; 

 elytris confuse griseo-variis j oculis nigris. 



Hab. — Sula. 



The prothorax is shorter, or rather, perhaps, proportionally 

 narrower, than in the two former species, and in the most perfect 

 of my specimens there is a decided, although interrupted, median 

 line on that part; the elytra are perhaps uniformly grey, but, from 

 abrasion, there are irregular dashes of reddish-brown in the above 

 specimen ; in another specimen the pubescence is nearly obliterated 

 and the elytra have a reddish-brown hue, clouded with darker 

 brown. 



Length 2| lines. 



^gocidnus costulatus. 

 IE, griseo-brunneus ; elytris singulis costis duabus basallbus ; 



oculis nigris. 

 Hab. — Bauka. 



The difference between this species and M. gramviicus is com- 

 paratively slight ; it consists chiefly in this, that the two principal 

 lines are slightly elevated between the rows of punctures, and the 

 spaces between these are scarcely pubescent, and there are no
