Genus Amara, Bon. 
1. Amara Vectensis. Oblonga convexa zenea nitida, interdum cz- 
ruleo-nigra: elytris punctato-striatis : antennarum articulis tribus 
primis rufo-testaceis: tibiis tarsisque rufo-ferrugineis. Long. 45 
lin. 
Oblong convex, body beneath shining black: head, thorax and 
elytra brassy brown, sometimes greenish brass, rarely blue-black, 
not always concolorous: thorax with an oblong deep impression 
on each side at the base, midway between the hinder angles and 
the dorsal furrow: elytra regularly and evenly striate, the strize 
deepening towards the apex and finely punctured for about two- 
thirds their length, the punctures gradually diminishing behind 
the middle and totally ceasing when the striz begin to deepen : 
within the outer margin an irregular line of deep impressions 
most numerous behind the middle: thighs pitchy black: tibize 
and tarsi rusty red or pitchy testaceous; anterior tibize with the 
spine at the apex tricuspid, the middle mucro being longest and 
stoutest and slightly curved, the inner one smallest : first, second, 
third and basal half of the fourth joints of the antennze red, the 
rest fuscous black. 
Originally taken at Ryde, Isle of Wight, and referred incor- 
rectly to tricuspidata, Dej. We are indebted to Dr. Schaum for 
correcting this error; and his opimion has since been confirmed 
by other continental entomoiogists, who have pronounced it to 
be an undescribed species. I have taken it annually for some 
years past in the north side of the Isle of Wight, but always 
sparingly, except on one occasion, when in company with my 
friend Mr. Wollaston (April 1846), it occurred plentifully among 
refuse left by a flood at Ryde. I have not seen it since. As the 
species requires a name, I have given it one commemorative of 
the locality in which it is (I believe exclusively) found. 
Genus Trechus, Clairville. 
2. Trechus incilis. Subtus niger, abdominis apice testaceo, supra 
nigro-piceus, thorace cordato, convexo, postice angustato, utrinque 
foveolato, angulis posticis mwas, acutis: elytris oblongo-ovatis, 
striis guatuor dorsalibus abbreviatis in singulo impressis: antenna- 
rum 2,3 et 4 articulis nigris, reliquis, palpis pedibusque testaceis. 
Long. 24 lin. 
Oblong ovate, dusky pitchy: head with two oblong frontal 
impressions : thorax heart-shaped, dise convex, broad im front,
