described below have mostly been procured in my travels in the Southern States ; 
a few are from California, but the distribution of this genus in the western and 
northern parts of the continent appears to be very limited. The new Cephennium 
is an interesting addition’ to our fauna. The new genus Brathinus must, 1 think, 
be considered as the American representative of Mastigus of the old world. 
Eutheia is not yet discovered on this continent, nor have we any form which 
corresponds to it. Our three genera may be easily distinguished as follows: 
A. Palpi maxillares articulo ultimo. minutissimo. 
Palpi labiales articulo primo elongato, mandibule 
apice emarginate (thorax amplus) : - CrpHennium Mull. 
Palpi labiales articulo primo brevissimo, mandibu- 
le acuminate (thorax parvus) S Scypmanus Latr. 
B. Palpi maxillares filiformes, articulo ultimo longiore Bratxinus Lec. 
Crepuennium Muller. 
Megaloderus Steph. Tyitosoma Wesmael. 
. C.corporosum, piceum flavo-pubescens, thorace angulis posticis subex- 
anatis, elytris vix punctulatis basi foveatis, striolaque externa notatis, pedibus 
ntennisque testaceis, his articulis tribus ultimis maioribus. Long. -035. 
New York, under stones in April, very rare. Blackish piceous, sparsely clothed 
with fine yellow hair. Head smal], smooth; antennez testaceous, half as long as the 
body, 9th joint one half thicker than the 8th, rounded,’a little transverse, 10th 
still larger, subtransverse, 11th longer than the 10th and obtuse. Thorax very 
transverse, sides parallel behind the middle, much rounded anteriorly, posterior 
angles rectangular, a little flattened. Elytra scarcely narrower than the thorax, 
convex, finely and sparsely punctulate, base impressed with a deep stria near the 
humerus, extending one-third the length of the elytra, and a large fovea half way 
between the stria and scutellum. Anus and feet bright testaceous, thighs not 
clavate. 
Scypmanus Latr. 
- [have adapted Schaum’s division of the genus to our native species without 
alteration, as it appears scarcely susceptible of any improvement; for convenience 
{ have divided the group (B) differently,as several European forms in it are want- 
ing in this country.
