SPHINDIDiE. 
This family forms a very good transition to the Cryptophagidte. 
The antennae are of a more perfectly clavicorn type than m. Qo«te, 
d have a large compact club, with the ninth joint variable size 
The mentum is very large, in striking contrast to the Cioidae where 
is unusually minute. The maxillary palpi are =^11 slender and pointed 
and the anterior coxse rather widely separated. YV 
tS continuous with the front, narrowed and continued over the larg r 
van of the mandibles, the labrum being small, almost^ atrophied m 
Odontosfihindus , the epistomal suture fine and posteriorly arcuate. 
The eyes are large, convex and coarsely faceted. The two genera be ore

Another ^enus,' Eurysphindus, has been described by LeConte, bin 
I have seen no example; the inferior flanks of the prothorax are said 
to be deeply concave and the body clothed with erect hair. 
Odontosphindus Lee. 
These species are much larger than those of Sphindus and are 
distinguishable at once by the characters of the table ; the two species 
are as follows :— 
Sides of the prothorax scarcely at all reflexed, finely margined. AtUmfenegmns^

Clavicornis is materially larger than denticollis, and has a large 
more transverse and more coarsely punctured prothorax.
