Tue fourth sub-family of the Crambide is that of the Crambidi, containing three genera, namely Platytes, 
Eromenes , and the typical genus Crambus. All the genera bear a strong family likeness to each other, and 
the whole group are popularly known as the Veneers, possibly from the streaking of the wings having some 
resemblance to the veining of rare inlaid woods. 
“The genus Platytes. The insects assigned to this genus have the antennz simple in both sexes ; and have 
the palpi projecting conspicuously beyond the head. They are generally of smaller size than the true Crambide, 
and their wings are rather shorter proportioned, but in repose they are-folded so as to give to the insect the narrow, 
elongated appearance peculiar to the whole family. They have not, however, the colours longitudinally divided, 
but are generally distinguished by pale transverse marks across the fore-wings. There is but one British species, 
which is included by some English authors in the extensive genus Crambus. 
Platytes Cerussellus (the Dwarf Veneer) is represented at No. 1. The female of the species is whiter, but 
with similar markings. The Caterpillar is unknown, but the moth appears in June and July. Kent and Devon- 
shire were formerly notable as places where specimens had been taken, but it has been recently captured at 
Lewes, Manchester, Mickleham, &c. 
The genus Hromene. The insects assigned to this genus, have the antenne simple in both sexes and the 
antenne extending conspicuously beyond the head. They are of the ordinary medium size of the typical Cram- 
bide, and the wings are narrowly folded when in repose ; but like those belonging to the preceding genus, they 
are not marked longitudinally by different tones of colour, having instead transverse markings, generally near 
the edge of the anterior wings. 
Evomene ocellea (the Necklace Veneer, No. 2). This pretty species is marked with a transverse row of 
head-like spots near the fringed margin of the anterior wings, from which it derives its popular name. It was 
formerly placed by Mr. Stephens in his genus Arawes, and described from an unique specimen, from the collec- 
tion of Mr. Haworth, taken near London. 
The genus Crambus. This genus may be said to form the type round which are grouped, not only the 
genera belonging to the sub-family Crambidi, but also those in the whole family Crambidae. The antennz are 
simple in both sexes, the palpi long and conspicuous, and joined together like a beak. The front-wings are of 
rather narrow proportions, and rather blunt at the fringed edge, but sometimes suddenly curving out at the angle 
into an abrupt point. The front-wings are generally marked by a pale central longitudinal streak, but there are
