This genus was described by Leconte under the name of Crymodes and figured under 
that of Crypheus, both names being preoccupied, the former in Lepidoptera and the 
latter in Coleoptera; it might be renamed Lecontia., The single known species is 
found under bark. New Ger .

Hab. Nortu America, British Colombia, Canada, Lake Superior !.—Mexico, Sierra 
Madre de Durango (Flohr). 
Dr. Horn, who has kindly forwarded a specimen for comparison, informs me that he 
has examples of this species from above Canada in the north to the lower U. S. border 
in New Mexico, and that the insect probably follows the Sierra Madre southwards at a 
high altitude (10,000 feet). 
The fragmentary specimen forwarded by Mr. Flohr is 21 millim. in length. 
SPITHOBATES. 
Last joint of the maxillary palpi broad and securiform, that of the labial palpi cylindrical or narrowly ovate ; 
inner lobe of the maxille furnished with a long sharp claw ; mandibles bifid, not or scarcely denticulate 
within; mentum very broad and short, about two and a half times as broad as long, the front angles 
rounded, the hind angles obtuse; ligula broad and very prominent ; head short, broad, rather convex, 
the epistoma not defined, the sides of the front obliquely converging, the apex truncate, the labrum pro- 
minent; eyes convex, entire, large or moderately large, coarsely granulated; antenne extending to a 
little beyond the base of the prothorax, with the joints from the fifth broader than the preceding three, 
or gradually widening outwardly and with joints 9-11 longer and wider than those preceding, the apical 
joint elongate-ovate, the basal joint stout ; prothorax longer than broad, rather convex, strongly constricted 
behind, much narrower at the base than at the apex, the sides (except at the base) more or less denticulate, 
the base truncate and margined ; scutellum transverse ; elytra moderately long, wider than the prothorax, 
parallel in their basal half and narrowing beyond, and with rows of punctures; anterior coxe contiguous ; 
intermediate and hind coxe narrowly separated, the former without visible trochantin ; fifth ventral 
segment as long as the fourth; legs moderately long, the femora rather stout, the tibiz with distinct 
spurs, the penultimate joint of all the tarsi small and short, the first joint of the hind tarsi rather long ; 
body convex, elongate, winged, sparsely clothed with decumbent hairs (which are serially arranged on the 
elytra), the upper surface, legs, and antenne also with scattered, long, erect bristly hairs. 
This genus is proposed to include two species from Central America. These differ 
a little inter se in the form of the antenne and in the size of the eyes; but in other
