resemblance in general form, and to some extent in details of structure, but 

 differs in the number of abdominal segments, and in the form of the head, as 

 well as in the elonuation of the first tarsal joint. 



In the male the antennae are larger and almost pectinate, and the sides of the 

 thorax are sinuate ; in the female the antennae are strongly serrate, and the sides 

 of the thorax are broadly rounded.

Pennsylvania, Dr. Melsheimer. This species is very similar to the preceding ; 

 it is, however, more dilated posteriorly, and the depression each side at the base 

 of the thorax is less deep. The sides of the thorax above and beneath, and the 

 tip of the abdomen, are indistinctly testaceous ; the tibiae and tarsi are pale 

 yellow, while in the preceding, as in the next species, the tibiae are black. The 

 sides of the thorax in the male are nearly straight, in the female they are broadly 

 rounded.

One specimen, Georgia. This species is more oblong than either of the others. 

 The sides of the thorax are slightly rounded towards the base, and not at all 

 testaceous ; the anterior margin is narrowly bordered with testact:ous ; the basal 

 impressions are large and deep, so that the whole region of the anterior angles 

 appears depressed ; the elytra, as in the two preceding species, are coarsely, not 

 deeply punctured ; at the base they are a little wider than the base of the thorax ; 

 posteriorly they are about one fifth wider than at the base ; the legs are black, 

 the base of the tibiae and the tarsi testaceous ; the prosternum is pale tes- 

 taceous.

The body is very broad, subquadrate and moderately convex; the thorax 

 yery short, stronj^ly narrowed in front, with the angles acute, and the sides 

 broadly rounded. The head is small and deflexed, the eyes entire ; the proster- 

 num is posteriorly produced, and rounded at the extremity, the mesosternum is 

 scarcely concave.

Pennsylvania ; a typical specimen of this very rare insect was given me by 

 Dr. Melsheimer. The antennae are, unfortunately, broken, so that, not know- 

 ing the number of long joints,! cannot determine whether the small round mass 

 following the basal joint should be considered as a single joint, or two joints 

 closely united.

Of this little family we have but two genera within our limits; in both of 

 them the antennx' are 11-jointed. In Sandalus' the joints of the tarsi are lobed
