from the Galapagos Islands. 35 
Pedoneces galapagoensis. Ped. ater, nitidus ; antennis pedibusque 
nigro-piceis ; capite thoraceque confertim punctulatis; elytris 
subsulcato-punctatis, interstitiis convexis punctis minutissimis 
adspersis.— Long. corp. 3 lin.; lat. 14 lin. 
Var. (3. Elytris sulcato-punctatis, interstitiis convexioribus, quarto 
et sexto elevatis, subcostatis. 
This species has the general form of the P. costatus, but the 
thorax is rather longer m proportion ; here the interstices of the 
strize of the elytra are simply convex, and do not form narrow 
ridges as in P. costatus. The legs have mmute yellow spiny hairs 
as in that species, and on the under surface of all the femora isa 
small brush of yellow hairs. 
Pedoneces costatus. Ped. uiger, parum nitidus ; antennis pedibusque 
rufo-piceis ; corpore oblongo, convexo; capite crebre punctato ; 
thorace confertim punctato, punctis longitudinaliter confiuentibus ; 
elytris sulcato-punctatis, interstitiis subcarinatis, alternis elevati- 
oribus, costatis.—Long. corp. 22 lin. ; lat. 1 lia. 
This species, which is from James’ Island, is easily distin- 
guished from the Ped. galapagoensis by the sharp keel-like ridges 
formed by the alternate interstices of the striz of the elytra, and 
by the narrowness of the other interstices : the thorax, moreover, 
is more strongly and more thickly punctured, and the punctures 
are oblong, and the greater portion of them are confluent, join- 
ing each other in such a way as to leave little, narrow, irregularly 
longitudinal ridges for the interspaces. The thorax is rather 
broader than long, subquadrate, the sides but shghtly rounded, 
and indistinctly smuated near the posterior angle, which is nearly 
a right angle ; the posterior margin is sinuated, presenting a con- 
vex outline in the middle, and a slightly concave emargination on 
either side near the angles. The elytra are scarcely broader than 
the thorax, of an oblong form, but little broader in the middle 
than at the base, and at “the apex they are rounded. The legs, 
which, like the antenne, are of a pitchy colour, have very small 
spiny yellowish hairs, and these become more dense and rather 
longer on the under side of the middle part of the hinder femora. 
The three terminal joints of the antennz are pitchy-red. The 
body is distinctly punctured beneath throughout. 
Eurynotus. In two species of Platynolus before me (one of which appears 
to be the P. gigas) I find the scutellum is scarcely to be seen, whilst in Lu- 
- rynotus it is distinct ; this, combined with the sinuated sides to the thorax of 
the former, and the thorax being broadest behind in the Eurynotus, will help 
to distinguish the two genera. I may add, the mesial lobe of the mentum 
is distinctly emarginated in Platynotus and truncated in Eurynotus: the 
structure of the tarsi and antennz also differ in these genera.
