BITOMA. 461 
Hab. British Honpvras, Belize (Blancaneaux); GuaTemata, Zapote, Capetillo, San 
Gerdnimo (Champion).—Brazit, Rio Janeiro 1. 
Resembles &. sulcata, but is rather narrower and less depressed. Head broad and 
short; epistome free, and with its outline continued as a fine margin over the eye. 
Antenne small; first joint nearly concealed, ninth scarcely broader than the eighth ; 
club broad, its two joints only loosely connected. Thorax straight at the sides, about 
as long as broad, the sides only obsoletely serrate; on each side of the middle with two 
sharply raised coste, the inner of which converge a little towards the base; on the 
front margin in the middle are two short obscure elevations; the surface granulate. 
Elytra with the usual five elevated coste, which extend unconnected to the tip, the 
interstices rather finely and obscurely sculptured. Legs short and rather stout; tibiee 
thicker towards the tip, but not angularly enlarged there. 
This species connects Bitoma with Xuthia. I have retained it in Bitoma as it is less 
cylindric in form than Xwthia, and the tibie are not angularly enlarged at the tip; 
moreover, in many of its characters it is approached by B. sulcata. | 
9. Bitoma pascoei, sp.n. (Tab. XIV. fig. 21.) 
Major, elongata, fusco-nigra, opaca; antennis’ tarsisque rufo-obscuris ; inequalis, prothorace lateribus ante 
medium dilatatis, rotundatis ; elytris argute carinato-tuberculatis. 
Long. 5} millim. 
Hab. Muxtco, Huitzo in Oaxaca (Hoge). 
Antenne with the first joint exposed, longer than the second, this latter a little 
longer than broad ; third joint slender, quite as long as the second; ninth joint small, 
but distinctly broader than the eighth; tenth and eleventh very broad, only loosely 
connected. Head broad, minutely tuberculate; eyes large, prominent. Thorax much 
narrowed behind the middle, the surface rendered very uneven by twelve elevations, 
two on the middle in front, two at the base in the middle, and four on each side. 
Elytra with about ten short carina-like elevations, making the surface very uneven, 
without impressed punctures, but with series of minute asperities. Legs slender; tibial 
spurs scarcely perceptible. Under surface punctate, opaque. 
Only one example has been procured of this very distinct insect. It somewhat 
resembles in form the largest examples of Jilestus terrenus, Pascoe. I have named it 
after the diligent English entomologist whom we have so recently lost. 
Notwithstanding the fact that this insect is so totally different in appearance from 
its more normal congeners, the structural characters that I can see in the single example 
at my disposal do not display any corresponding dissimilarity.
