464 COLYDIIDA. 
3. Lado funestus. (Tab. XIV. fig. 24.) 
Subcylindricus, opacus, tenuiter ciliatus, niger, elytrorum basi rufescentibus ; antennarum basi, tibiis tarsisque 
fusco-rufis ; ecostatus, elytris seriatim punctatis. 
Long. 3 millim., lat. ? millim. 
Hab. Guatemata, Totonicapam 8500 to 10,000 feet (Champion). 
Basal portion of antenne yellow; club large, black. ‘Thorax longer than broad, very 
slightly narrowed behind, opaque, very obscurely sculptured, but with irregularly placed, 
distinct sete. Elytra long and narrow, black, with the base reddish, quite dull, densely 
seriately sculptured, and with a barely perceptible elevation of the alternate interstices. 
Only one example was obtained of this very distinct species. 
LASCONOTUS.

About ten species have been assigned to this genus, all of them being North- 
American. 
1. Lasconotus sulcifer, sp.n. (Tab. XIV. fig. 25.) 
Parvus, anguste oblongus, fuscus; antennis pedibusque testaceis ; prothorace elytrisque longitudinaliter cos- 
tatis, his apicem versus late profundeque longitudinaliter, communiter sulcatis. 
Long. 23 millim. 
Hab. Guaremata, San Gerénimo (Champion). 
Antenne with joints 3-8 quite small, the three-jointed club large and abrupt. Head 
deeply and broadly bi-impressed. Thorax longer than broad, finely margined at the 
sides, delicately punctate and pubescent, with a broad depression along the middle limited 
on each side by an obtuse costa; these costa do not reach quite to the front margin, 
but they are each surrounded at the end by a slight curvate elevation; the extreme 
base of the thorax is strongly constricted, the true hind angles being thus concealed. 
The elytra have the shoulders prominent in front; they are broadly and deeply longi- 
tudinally depressed along the middle; the suture is scarcely costate in front, but is 
distinctly so towards the apex; the first interstice is feebly costate, but only on the basal 
portion ; the third interstice limits the broad depression and is strongly costate, and 
outside it there is also another costa, strongly raised and extending from the base to 
the apex; the intervals bear obscure serial punctures. 
Closely allied to L. pusillus, Lec., but narrower, with the shoulders more prominent 
anteriorly, the elytral depression much more marked, and the coste more sharply 
elevated. We have received nearly twenty examples; they vary in colour, some being 
brownish, but in other respects are very constant.
