COLEOPTERA 171 



(44) Oodenias konamim, sp. nov. 



Ovatum, robustum, nigroaeneum, opacum vel minus nitidum. Rostrum strigoso- 

 punctatum. Antennae graciles, minus breves, articulo funiculi primo brevi, quam 

 secundus evidenter breviore. Pronotum basi latum, opacum (rare subnitidum) subtiliter 

 punctatum. Elytra sat lata, subopaca, rarius nitida, grosse seriatim punctata, plerumque 

 obscure vel vix evidenter striata, interstitiis nonnunquam convexiusculis, haud dense 

 punctulatis. Long. 5 — 6 mm. 



A large, wide, and robust species, generally dull, with the elytra a little shining, 

 sometimes quite brightly so. The rostrum is so punctate as to have an appearance of 

 longitudinal strigosity, but in some examples this is less evident. Prothorax generally 

 quite dull from the microscopic rugulosity of the surface, finely, obscurely, and remotely 

 punctured. In a few examples the puncturation is more evident. Elytra with series 

 of coarse punctures, sometimes placed in evident striae, owing to the slight but evident 

 convexity of the interstices, but the striation is vague and shallow. In many examples, 

 however, there is little or no trace of interstitial convexity. The metasternum and base 

 of the abdomen beneath are coarsely punctured. In spite of the variation in detail of 

 the sculpture, this species is not difficult to recognize, by its large size and robust form, 

 and the more or less dull surface. It is perhaps most nearly allied to O. scidpturahiin, 

 but that species is of shorter and more subquadrate form, and generally has the 

 interstices of the elytra more distinctly convex. 



Hab. Hawaii, Kona district (4000 ft.). About 40 examples were taken. 



(45) Oodenias rnultifornte, sp. nov. 



Nigroaeneum, nitidum, ovatum. Antennae sat graciles et elongatae, articulo 

 funiculi primo minus elongate, quam secundus breviore. Elytra nitida, seriatim sat 

 grosse punctata, interstitiis punctulatis. Long. 3 — 5 mm. 



To the above species I refer all the specimens of Oodenias taken by me on Hawaii, 

 except the series of O. konanuni and a few specimens, which I consider a variety of that 

 distinct species O. mauiense. If I am right in my conclusions, the variation exhibited 

 by O. multiforme is much greater than that of any other species, so much so that the 

 extreme forms would not only appear to be totally distinct, but not even very closely 

 allied. When, however, a great many examples are compared, these extreme forms are 

 so connected by intermediates, as to make it impossible to decide where any line 

 of separation can be drawn. For this reason we have not attempted to draw up any 

 detailed description of the species, as such could apply to but a fraction of the examples 

 we have examined. Indeed apart from generic characters, there are probably none 

 which do not exhibit more or less variation. The brief description given above applies 

 to a common form of the insect, and a number of this form were taken at Kilauea,
