LOGANIUS. 129 
rounded, not depressed. Elytra a little narrower than the prothorax, and nearly one-half longer, almost 
truncate and finely margined at base, humeral prominences small, the sides parallel to the posterior third, 
the apex circularly rounded ; surface shining over the anterior third, then dull, with strong punctured 
Strie, shallow at the base, interstices narrow, flat, transversely rugose, punctured in irregular rows, 
subtuberculate and bearing short erect seta towards apex. Underside finely punctured and pubescent; 
the legs obscurely reddish. 
Hab. 1 Mexico (coll. Blandford). 
One example has been sent me by M. Grouvelle, from Mexican tobacco. I am 
uncertain as to the sex, as the antennal cirri appear too fine for a male, whereas the 
front, though scarcely impressed, is villous, usually a male character. In the single 
specimen I am unable to make out the sutures of the club, but its. shape decides me 
to refer the insect to this genus and not to Ceratolepis. In appearance L. longicollis is 
like LZ. flavicornis, Chap., more than any other species, but it is more elongate and 
has not the interstitial carinee which distinguish that insect. 
2. Loganius panamensis, sp. n. 
Oblongo-ovalis, niger; antennis fusco-testaceis, clava obscuriore ; tibiis anticis tarsisque rufescentibus ; prothorace 
haud transverso, parcissime pubescente, nitido, punctato, punctis in antica parte strigosis; elytris pube 
brevi vestitis, tenuiter striatis, interstitiis anterius rugosis posterius multipunctatis. 
Mas. Fronte impressa, breviter bifasciata. 
Fem. Fronte haud impressa. 
Long. 2—2°5 millim. 
Oblong-oval, black. Front (¢) impressed, the impression eireular and subconcave, closely and rugosely 
punctured, above with a small fasciculus of fulvous or yellow hairs on either side, below separated from the 
epistoma by a transverse ridge; front (@Q ) flat, but not impressed, dull, closely reticulate and punctured, 
subglabrous ; antenne pitchy-testaceous, funiculus appendiculate in both sexes, the cirri ( 2) shorter and 
finer, club obovate, with a single curved suture, infuscate and entirely pubescent. Prothorax as long as 
broad, bisinuate and feebly bordered at base, the sides elliptically rounded, the apex obtuse; shining, 
sparsely hairy anteriorly, with rather close oblong punctures, the interspaces strigose towards apex, 
nearly smooth towards base, median line distinct throughout, elevated in front. Scutellum small, 
triangular, rather convex. Elytra scarcely as wide as the prothorax and little longer, with sinuate and 
elevated basal borders, nearly parallel-sided to the middle, thence obliquely rounded; surface very 
gradually declivous from before the middle, finely striate; interstices nearly flat, rugose at base, then 
finely multipunctate, covered with short decumbent fuscous or yellowish bristly hairs, the sutural 
interstice depressed at the base. Underside black, punctured, and shortly pubescent. Legs piceous-black, 
the tibis, especially the anterior pair, and tarsi reddish. 
Hab. Panama, Tolé (Champion). 
Sixteen specimens. 
3. Loganius atratus, sp. n. (Tab. VI. fig. 2.) 
Oblongo-ovalis, nitidus, glaber, ater, antennis pedibusque piceis; prothorace subtransverso, anterius subcon- 
stricto, subtiliter discrete, ad latera fortius punctato, linea media levi; elytris striato-punctatis, interstitiis 
subconvexis, uniseriatim, ad basin saltem biseriatim, punctatis. 
Long. 2:4 millim. 
Oblong-oval, deep black, shining, glabrous above, with exception of the head, which is dull, alutaceous, and 
rather closely punctured ; front with a shallow subtriangular impression over the mouth, its margins
