CURCULIONID®—ALOPHIN &. WS 
spaces with a median row of short stiff bristles. Legs rather short and 
stout, the tibiee straight, except the hind pair, which are longer and gently 
arcuate, the femora a little arcuate, the tarsi more (in the hind legs less) than 
half as long as the tibiee, constructed exactly as in Trichalophus, the only 
living genus of Alophinze I have been able to examine. ‘The fore cox are 
attingent, the middle coxze narrowly, the hind coxze widely separated, the 
last by nearly the diameter of the coxal cavities. The third and fourth 
abdominal segments are shorter than the others but not very short, being 
together a third longer than the second; the first and second segments are 
separated by a straight suture. 
It is noticeable that in the forms with short rostrum, the specimens are 
preserved about as often on a dorsal as on a lateral view, while in those 
with long rostrum, it is rare to find one preserved other than lying upon its 
side; it is not unlikely that in the former the body may be relatively 
more depressed, in the later more compressed than in the alternate type. 
Nine species are known, all from Florissant, and from Florissant only, 
where it is the most abundant type of Rhynchophora, and may be regarded 
as typical of these beds. -
