EPICERUS. 117 
27. Kpicerus griseus. 
Epicerus griseus, Boh. in Schénh. Gen. Cure. vi. 2, p. 2827. 
Hab. Mexico !, Playa Vicente, Orizaba, Cordova (Sallé), Jalapa (Hoge). 
We have received seven examples of this species; it is distinguished from FE. sphe- 
rotdes chiefly by the broad depression on the front of the rostrum, and also is rather 
larger in size. | | 
I am by no means sure as to the distinctions between Boheman’s EF. griseus and 
E. spheroides; the small series of the two we have received are variable in respect of 
the characters mentioned by the Swedish writer. I have therefore arbitrarily divided 
our examples, as above stated, until a larger number of specimens shall have been 
obtained, so as to allow the sexes to be distinguished, and thus facilitate the solution 
of the question as to whether EZ. griseus and E. spheroides may not be the sexes of one 
variable species. An example of EH. griseus communicated by Dr. Aurivillius from 
Schénherr’s collection agrees with our examples. 
28. Epicerus spheroides. 
Epicerus spheroides, Boh. in Schénh. Gen. Cure. vi. 2, p. 2837. 
Hab. Mexico 1, Oaxaca (Hége), Cordova, Orizaba, Playa Vicente (Sallé). 
I refer to this species a dozen examples which agree moderately well with Bohe- 
man’s description, and with three specimens in my own collection determined by the 
late M. Jekel as being E. sphaeroides. We have also received some half dozen 
specimens that are very variable as regards the characters supposed to be distinctive of 
E. spheroides and £. griseus. The example of E. sphwroides communicated by 
Dr. Aurivillius from Schonherr’s collection I cannot distinguish from EF. griseus; but it 
is probable that other examples in his collection may prove to have the rostrum 
unimpressed, as stated in the description. 
29. Epicerus oscillator, sp.n. (Tab. V. fig. 8.) 
Convexus, niger, griseo-squamosus; prothorace conico-cylindrico, obsolete inzquali, haud punctato; elytris 
minus fortiter seriatim punctatis. 
Long. 74-10 millim. 
Hab. Mexico, Capulalpam (Sa//é). 
Rostrum short and broad, in front indistinctly and broadly impressed; scrobes short, 
rather broader and more indefinite behind than is normal in Epicwrus. Thorax 
narrowed in front, not constricted behind, the surface very slightly uneven but without 
channel or punctures. Elytra rather short, much elevated, with somewhat indistinct 
series of punctures. 
This insect resembles the shorter and more strongly-scaled varieties of E. mexicanus, 
E. nebulosus, and E. sqguamosus. It has the scrobes shorter and rather broader and
