of two new Genera of Carabideous Insects. 279 
apicalibus brunneis, superficie corporis levi; singulo elytro- 
rum striis 7 simplicibus et gracillimis instructo, spatio inter 
strias 6 et 7, ad latera, in carinam elevato spatioque intus 
marginem lateralem punctis parvis rotundatis impresso. 
Long. corp. lin, 183, lat. elytr. pone medium lin. 44. 
Habitat in Guinea. 
In Mus. nostr. D. Westermanno amicissime communicatus. 
Hettvopes, Westw. (Plate XXi. fig. B. and details.) 
Caput maximum, (prothorace multo majus,) porrectum, pone 
oculos in collum contractum; vertice ineequali, levi, haud 
punctato, (fig. Ba, caput subtus visum). Labrum porrec- 
tum, latius quam longum, antice in medio parum emargina- 
tum, angulis posticis rotundatis. Mandibule porrecte acute, 
margine interno inermi, apice parum acuminate, (fig. Ba*). 
Mazxille elongate, graciles, apice subunguiculate. Palpi in- 
terni valde curvati, 2-articulati. Palpi externi maxillis vix 
duplo longiores ; articulis 2 et 3 subaqualibus, hoc extus 
parum curvato; 4to dimidio breviori, intus inflexo, apice 
crassiori, (fig. Bc). Mentum latum, in medio valde emargi- 
natum, dente medio fere obliterato, (fig. Bat). Labium 
angustum, gracile, apice rotundato, (fig. Bat). Palpi labia- 
les articulo 2do sequenti crassiori et longiori, intus setoso. 
Antenne graciles, haud compress, longitudine mediocri, 
articulo 2do plus dimidio longitudinis 3tii, 4to Sto breviori. 
Prothorax truncato-cordatus, fere latitudine capitis (pone 
oculos) equalis, marginatus. Llytra depressa, ad partem 
mediam latiora, punctatissima. Pedes mediocres, tibiis anticis 
ante apicem emarginatis ; tarsis in specimine unico simplici- 
bus, articulo 4to parvo, calcaribus brevibus. 
This genus approaches nearest to /Zelluo in its general charae- 
ters, although in its habit it resembles Morio, but in the particular 
structure of the parts of the mouth it is certainly not far removed 
from Anthia. Its locality, Ceylon, combined with its large head, 
&c., renders it an interesting link in the tribe of beetles to which 
it belongs. Unfortunately the extremity of the elytra are in- 
jured, so that I cannot determine the extent to which they may 
have been truncated. 
Helluodes Taprobane, Westw. 
(Plate XXI. fig. B.) 
Niger, nitidus; labro, femoribus apiceque abdominis piceo-rufis.
