the thorax; this latter without discoidal punctures. Elytra about as long as the 
thorax, each with about a dozen irregularly placed obscure punctures, each of which 
bears a conspicuous erect black seta, the larger of these sete being three or four placed 
at each outside; touching the epipleural margin there is a series of obscure punc- 
tures, the punctures on the posterior part of this series distant and obsolete. Hind 
body with the two basal segments black, strongly iridescent. The male has a slight 
emargination in the middle of the hind margin of the last ventral plate. 
This species apparently varies much in colour: all the red parts may become black, 
except the antennz, legs, and two apical segments of the hind body, and, on the other 
hand, the head may be in greater or less extent red. From Panama I have seen only 
two individuals, both of them extreme colour-varieties, but very different from one 
another. 
This insect was found amongst branches cut from trees. 
6. Quedius jocosus. (Tab. VIII. fig. 6.) 
Nitidus, rufus; capite abdomineque nigris, hoc apice lete rufo-testaceo, pedibus testaceis; elytris thoracis 
longitudine, punctis nonnullis magnis seriatim impressis ; abdomine crebre subtiliter punctato. 
Long. 103 millim. 
Hab. GuatTEMALA, near the city, at an elevation of 5000 feet (Champion). 
The head is broad and short, shining black, the clypeal membrane pale, almost ivory- 
like, the mandibles and palpi red. The punctures on the elytra are rather large, and 
are disposed serially, five or six along the suture; a similar number on a series within 
the shoulder, two punctures being interposed on the disk between these two series; at 
the epipleural margin there is a regular series of twelve to fourteen setigerous punctures, 
and above these there are at the side three or four elongate outstanding black sete. 
The basal segment of the hind body has only a few punctures, a large space on it being 
bare, but the segments beyond the second are rather closely and regularly punctate ; 
the pale colour is confined to the two terminal segments and the apical processes. The 
male has a deep notch on the last ventral segment. 
Mr. Champion found three individuals of this elegant insect running on the banks of 
streams, and I have for some years preserved an individual in my collection. There is 
no sexual difference of coloration. 
7. Quedius graciliventris. 
Nigerrimus, nitidus, politus; capite inter antennas abdominisque apice rufis; mandibulis, palpis, antennarum 
basi pedibusque anterioribus testaceis, pedibus intermediis fusco-testaceis, tarsis nigris ; elytris longioribus 
quam prothorax, punctis nonnullis haud magnis impressis ; abdomine gracile fere impunctato. 
Long. 9 millim. 
Hab. Panama, Volcan de Chiriqui between 2000 and 6000 feet (Champion). 
The head is orbicular, but not very large ; the red colour on its anterior part is only
