496 - Mr. G. J. Arrow on the 
development of the pulvillus as a broad setose lamina, parti- 
cularly as it occurs in combination with claws furnished with 
broad laminge at the base, is, so far as I know, unique 
amongst the Melolonthing. The antenne are of peculiar 
structure, the joints being reduced in number to eight, and 
the three composing the club broader at the base and less 
closely fitting than usual. The mandibles are small, with a 
large molar “at the base, and the maxille are powerfully 
developed. The mentum is very tumid beneath, and the 
labial palpi have the penultimate joint curiously bent, giving 
the organs an elbowed form. Finally, the sexual differences 
are interesting, the male having a silky bloom upon the 
elytra, in addition to dilated and velvety front and middle 
tarsi, as in Apogon’a and other genera. 
Lepidoderma pica, sp. 0 
Nigra, nitida, elytris minus nitidis, postice fasciis duabus oblique 
transyersis (interdum intus connexis) nonnunquam etiam maculis 
minoribus anterioribus albo-squamosis; capite grosse punctato, 
sat longe fulvo-piloso, pronoto glabro, hic ibique minute punc- 
tato, antice parce fulvo-piloso, prope margines squamis albis 
irregulariter sparsuto, lateribus in medio obtuse angulatis, angulis 
anticis fere rectis, posticis acutis ; scutello laxe punctato, margine 
angulisque anticis setosis; elytris minutissime et densissime 
punctulatis, singulo areis duabus levigatis; propygidio dense 
setoso, pygidio ruguloso, nudo; pectore dense flavo-piloso, medio 
levi, lateribus albo-squamoso; abdomine medio polito, lateribus 
quingue-fasciatis, fasciis dense albo-squamosis. 
Long. 29-33 mm.; lat. max. 16-17 mm. 
This is a very distinctively marked species, being entirely 
black, with white scales which form two transverse, slightly 
oblique bands upon the hinder half of each elytron, nowhere 
reaching the margin. These bands are of vocab size, and 
in one specimen are united at their inner ends by a straight 
line of scales near the suture and parallel toit. The pattern 
thus produced is repeated in this specimen by a similar figure 
just in front, but smaller. In others this is represented by a 
tew scales only. ‘The pygidium is almost without scales, 
the propygidium ee setose, and the abdomen smooth and 
shining in the middle and finely punctured at the sides, 
where there are five transverse bars of dense white scales. 
‘he pronotum is very shining and the elytra are subopaque. 
The male has the antennz rather longer than the female, 
the club consisting of five instead of four joints, and the tarsi 
are distinctly longer. 
LL. pica possibly resembles L. nigra, Nonfr., but the
