Labentia infantaria, Gueuee, n. s. 
Minima. Alee sericece, cinereo-grisew, nervis nigro albidoque punctu-

It is the smallest of the Larentice, and does not exceed an Eupithecia in size. 
All the wings are silky, grey, very slightly greenish, the fringes concolorons : su- 
perior traversed by many fine sinnated and toothed lines, the two most evident of 
which border the median space, which includes two others and a dot ; behind thia 
space the nervures are dotted with black and pale : inferior a little paler, unicolo- 
rous above, with traces of lines beneath. Body grey, without markings. Palpi 
sensibly produced beyond the head, and forming a blunt triangular beak. Antennae 
filiform ; but I think the specimen before me is a female.

This charming Larentia resembles in its colours our species of Catocala with 
yellow inferior wings. Superior blackish cinereous, with the ordinary lines of the 
Larentice ; the two median dai'ker : inferior beautiful bright fawn-colour, with a 
narrow toothed blacked border, and black fringe ; two median lines sinnated, black ; 
afterwards is the commencement of a third. Beneath all the wings are golden 
yellow, with a cellular dot, two fine wavy lines, the border, and the fringe, black ; 
all the markings very distinct. Body grey above, whitish beneath, without mark 
ings. The antennae of the J are strongly pectinated ; those of the ? filiform. 
The latter sex difi'ers only by its scarcely paler colour.

It has almost the size and cut of oui- ahhreviata, and its mai'kings, which are 
very distinct, resemble those of certain CidaricB. Superior wings pale green and 
testaceous mixed, but this last colour is probably only faded green ; the base and 
spaces between the lines green and black ; afterwards comes a broad arcuated and 
strongly interrupted brown band, touching the two margins, and denticulated ex- 
teriorily ; the space which follows is greenish-white, traversed by several green 
denticulated lines, the last but one of which is mixed with black in several places, 
especially in the cellule, where that colour forms a veiy distinct arc ; the rest of 
the wing is divided by the subterminal line, which is pale, fine, denticulated, and
