Sp. 3. Dillwynii. Plate xxiii. f. 3.—JEneo-cupreus, nitidus, thorace trans- 

 vershn subrugoso, elytris punctato-striatis, interstitiis subrttgosis, antennis 

 apice tarsisque fuscis. (Long. corp. 2\ lin.) 



Eu. pygmaeus. Olivier f—Steph. Catal. 228. No. 2338. 



Brassy-cop-per, very glossy : head punctate, with a frontal depression, and faintly 

 rugose transversely : thorax with the sides dilated, the disc very thickly and 

 finely wrinkled transversely : elytra somewhat unequal, with the shoulders 

 anteriorly angular, the disc rather irregularly pundate-striate, with the inter- 

 stices somewhat rugose ; each elytron with two bronzed depressions on the 

 disc: legs and antennae brassy, with the tip of the latter and the tarsi fuscous. 



As this splendid insect does not exactly accord with Olivier's description of Eu. 

 pygmseus, which he describes as having the thorax smooth and the elytra 

 punctate, I have named it after its captor, my friend, L. VV. Dillwyn, Esq. 



I have seen one specimen only of this beautiful insect, s^hich was 

 given to me by Mr. Dillwyn, and was " taken on July 29, 1820, 

 among herbage on a hedge bank by a path near Penllergare, be- 

 tween Tyrdonkin and Cefnadley." — L. W. Dillwyn, Esq. 



Family LII.— CASSIDIAD^, Leach. 



AntenncB inserted at a distance from the mouth, approximating at the base, the 

 base itself generally concealed beneath the anterior margin of the thorax. 

 Palpi small : head horizontal, concealed beneath the thorax ; the latter gene- 

 rally semicircular: mouth received against the anterior margin of the sternum: 



form : head small, retracted : thorax rather narrower than the elytra; the latter 

 convex : body ovate : legs moderate, simple. 



+ Sp. 1. flavicornis. Punctata, viridi-cenea, antennis pedibusque Jlavis. (Long.

 Cr. flavicornis. Fahricius.—JFilkin s Cat.(! J—Steph. Catal. 4.14.iVo.2338 * note. 

 Brassy-green, punctate : antennae yellow : elytra somewhat punctate-striate, body 



brassy beneath : legs yellow. 



This insect is introduced in the Catalogue of the rare British Insects in the 

 collection of Mr. Wilkin ; but as it is a native of South America, it is doubtless 

 not indigenous.
