NOTHIOPHILUS, Dumer. 
1. N. scmistriatusy Say. Closely allied tQ N. 
aquations y F., and biguttatusy F., partaking of .the 
characters of both. Dejean states that it “ ne 
differe peut-etre pas de Pune des especes d’Eu- 
rope,” but he does not inform us which of the spe- 
cies ; indeed they are ail so closely allied., that 
considerable examination is required to detect 
permanent differences. The elytral puncture is 
small and like that of aquations placed nearer the 
base than that of the biguttatus, but the striae, 
like those of the latter, are not obsolete towards 
the tip ; the four basal joints of the antennae are 
rufous, &c. 
2. j)orreotuSy^^y. M. semistriatusy Var. 
b. Say. Trans. Amer. Philos. Soc. On close 
examination I am convinced that this deserves to 
rank as a separate species. In comparison with 
either of the species above mentioned the thorax 
is much more contracted behind, and the labrum 
is more advanced. The feet are entirely rufous, 
even including the thighs. The head is, larger 
than that of the semistriatuSy and the strias are 
not so deeply impressed, but the impressed point 
of the elytra is similarly situated, though perhap« 
a iittle fhrther back. The length is much the 
same. The colour is tinged with violaceous. 
CHL^NIUS, Bonelli. 
1. 'C. pusillusy Say. Trans. Amer. Philos. 
Soc. Since described by Dejean under the name 
of elegantulus, 
2. C ^omenfosus, Say. (Epomis.) Trans. Am. 
Philos. Soc. This species has been referred to 
this genus by Dejean ; the palpi are not sufficient- 
ly securiform, for Epomis. 
3. C. circumoinotusy Green tinged with viola- 
ceous ; edges rufous. 
Inhab. Louisiana. 
Body green, more or less tinged with violace- 
ous and brassy, punctured : head minutely and 
confluently punctured ; in the middle tinged with 
bronze ; lateral edges dark purplish : antennas 
reddish brown, three basal joints pale yellow with 
rufous incisures; labrum and mandibles honey yel- 
low, the latter black at tip : palpi y ellow ; ter- 
minal joints honey yellow : thorax deeply punc- 
tured, sparse near the anterior angles, and al- 
most wanting each side of the middle ; dorsal 
line acute almost obsolete ; basal lines widely in- 
dented ; lateral edge regularly arquated, dull 
rufous ; basal edge rectilinear in the middle and 
a little oblique each side, making the angles ra- 
ther more than rectangular ; green a little ting- 
ed with brassy : szutel dark purplish : elytra with 
profound, obsoletely punctured striae ; interstitial 
spaces flattened, punctured, sericeous ; rather 
dull green with a slight violaceous reflection ^ — 
exterior and apicial edge, dull rufous : beneath
