[March, 
veiy much broader and less convex than D ever illi, and very differently 
striated, &c. ; the strongly rounded thorax, superior size, different 
colour, Ac., distinguish it readily from vulcanus. 
C. LJETUS, sp. nov. 
Convexus, nitidus, nigro-brunneus ad ceneum aecedens, antennis palpis 
pedibusque fer r ugineis vel rufo testaceis ; capite medioeri, oculis prominulis ; 
antennis corporis dimidio multo brevioribus, submoniliformibus ; prothorace 
transi t) so, cordato, canaliculato, antice fere truncato, trans basin sparsim 
punctato, angulis posticis rectis; elytris ovalibus, subtiliter striatis, striis 
externis subtilionbus, striis antice subtiliter punctatis, humeris rotundatis. 
Pong. 4f — 5 mm. 
Haleakala, Maui ; under stones, &c., at an elevation of about 
4000 ft. 
Another species of the cordaticollis group, nearest, I think, to 
vulcanus ; it may, however, be easily distinguished from all its allies 
by the shortness of its antennae, which, when set back, will not quite 
reach the base of the scutellum. 
C. robustus, sp. nov. 
Fort i ter convexus, subnitidus, obscure viridi-ceneus, antennis palpis pedi- 
busque rufo-piceis; capite niediocri, oculis prominulis; antennis corporis 
dimidio brevioribus ; prothorace transverso, cordato, canaliculato, antice fere 
truncato, basi utrinque foveolato, trans basin punctato, angulis posticis rectis 
(nec abrupte) ; elytris ovatis, fortiter regulariterque striatis, striis antice 
obscure punctatis, humeris prominulis. Long. 6 mm 
A single specimen occurred to me in moss, at an elevation of 
about 4000 feet, on Haleakala, Maui. 
This species is not very close to any other with which I am 
acquainted. The combination of strong regular striation "with great 
convexity separates it from all its congeners with the thorax of cor- 
date form.

BEMBIDLUM (NOTAP HUS). 
B. spurcum, sp. nov. 
Minus convexum, nigrum ad cupreum aecedens, antennis palpis pedibus 
et elytrorum macula postied plus minusve rufescentibus ; capite medioeri, oculis 
Varum convexis, antennis corporis dimidio longioribus ; prothorace transverso, 
cordato, leviter canaliculato, antice emarginato, basi lato, utrinque foveolato, 
angulis posticis rectis; elytris oblongis, minus fortiter punctato-striatis, 
inter stitiis planis, humeris rotundatis. Long 41 mm * 
Haleakala, Maui ; in decaying leaves, at an elevation of about 
4000 feet.
