ml impressed line and another from the humerus not 
reaching the tip : ter gum black with a piceoiis tinge : feet 
yellowish- white ; tibim and tarsi a little darker. 
Length over three-twentieths of an inch. 
Gravenhorst considered this insect as specifically iden» 
tical with his piceus^ but in his remarks on that species 
he states that ‘“huic Oxytelo alius affinis est,quam D. Prof. 
Enoch O. sculptus iiuncupauit. Differt thorace lateribiis 
subrotimdatis, basin versus paulo angustiore, coleoptris 
breviore et paulo angustiore, fusco sen rufo ; coleoptris 
quadratis, rufescentibus sen piceo-mfo.” These diffe- 
rences of character, indicate a difference of species.— 
It is the Aleocharasculpta of Melsheimer's catalogue. 
£. O. rugulosus. Black ; logitudinally wrinkled ; ely- 
tra obscure piceous. 
Inhab. Mexico. 
Bodtj black, rather short, with numerous punctures, 
somewhat confluent into longitudinal wrinkles : head 
with three grooves, rather slightly impressed, the lateral 
ones dilated : antennx brown, dull honey-yellow at base : 
palpi dull honey-yellow : thorax with three grooves, of 
which the middle one is wider before and the lateral ones 
wider behind ; each side a little concave, the edge slight- 
ly reflected : anterior angles acute ; lateral edge arquated; 
rounded behind : elytra transverse quadrate, blackish-pice- 
ous : ter gum with dense, minute punctures : feet honey- 
yellow. 
Length less than one-tenth of an inch. 
This does not altogether agree with the var. a. of the 
carinatus of Gravenhorst and to which he has given the 
name of insignitus. The present species is proportional- 
ly much shorter than the earinatm. It is not more than 
half the length of that species. It is more than probable 
that the insignitus is also a distinct species. 
I obtained three specimens of the rugulosus in Mex- 
ico. 
3. O. cordatus^ Black: elytra whitish, %vith a com- 
mon brown spot. 
Inhab. Virginia.
