Metisopus (F. Bates, Trans. Ent. Soc., 1873, p. 370) is the 

 most nearly allied genus ; in it the tarsal vestiture is confined to the 

 tips of the first three joints. 



The type !s No. 696, now Leiopeplus expolitus. 



Cerodolus. 



Nov. gen. 

 (Sharp ; Trans. Roy. Dub. Soc., 1886, p. 410.) 



Corpus ovale, convexum, absque pubescentia. Pedes graciles, 

 tarsi subtus sat longe pubescentes, articulo penultimo simplice pre- 

 cedente fere angustiore. Prosterm processus latus, inter pedes im- 

 pressus, apice libero ; mesosternum declive. 



Antenna slender, the apical joints scarcely thicker, the third 

 joint a little longer than the fourth ; antennary orbits a little 

 elevated ; basal joint of antenna partly covered above ; terminal 

 joints of palpi securiform ; mentum rather broader than long ; a 

 little narrowed towards the base ; the front oblique on each side, 

 so as to form an angle in the middle ; the surface not flat, the pro- 

 minent antero-medial part being bulged : this apparently accom- 

 modates the ligula behind it, for this part is but little exposed ; 

 front coxae rather small, rather widely separated; the prosternal 

 process impressed between the legs, and behind them not bent up ; 

 its extremity capable of close apposition with the vertical front of 

 the posterior part of the mesosternum ; metasternum very short ; 

 hind coxae broadly separated ; the process between them neither 

 truncate nor acuminate in front, but intermediate in shape between 

 these two forms ; ventral segments as in Adelium ; epipleura 

 moderate, gradually narrowed from the base to the apex ; legs 

 slender ; tibiae cylindric, smooth ; tarsi quite slender, not densely 

 pubescent beneath. 



This is another genus of Tenebrionides , not closely allied to any 

 other ; but will probably be found allied to some of the little-known 

 forms of the family from New Caledonia, such as Isopus. In the 

 New Zealand list it will take its place next to Adelium. 



2058. C. chrysomelpid.es, n.s. (Sharp; Trans. Eoy. Dub. 

 Soc., 1886, p. 411.) Ovalis, niger, supra aeneus, antennis pedibus- 

 que rufis ; capite thoraceque subtiliter punctatis, elytris subopacis, 

 seriatim foveolato-punctatis. 



Long., 7mm. 



Antenna longer than head and thorax ; penultimate joint about 

 as long as broad ; head scarcely half as broad as the elytra ; thorax 

 a little narrowed from the base to the front, with a very slight sinua- 

 tiou of the sides in the front of the hind angles ; these about rect- 

 angular, but minutely rounded ; the lateral margin very fine ; the 

 front not emarginate ; the base a little sinuate on either side ; the 

 surface finely and not densely punctate, with a minute depression 

 on the base on either side of the middle ; scutellum transverse ; 

 elytra convex, each with eight series of foveiform punctures, some-
