NOSODENDRON. 671 
of the base of the elytra, but is very dense on the apical portion of the latter; on the 
other hand, the large serial punctures are very definite on the base of the elytra, but 
become quite fine behind, and are lost among the minute punctuation of the apex. 
Mentum divided into three longitudinal areas by a pair of parallel lines down the 
middle, the middle one of the three areas being very narrow. 
2. Nosodendron subtile, sp. n. 
Breviter ovale, nigerrimum, sat nitidum, pedibus piceis, antennis testaceis; elytris punctorum seriebus et 
apicem versus dense minute punctatis. 
Long. 3 millim. 
Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion). 
Resembles JV. championi, but distinct by the minutely punctate apical portion of the 
elytra, by two of the series of elytral punctures being incomplete near the scutellum, 
and by the differently formed mentum, which is coarsely punctate and nearly simple, 
being only transversely impressed in front. The present insect is shorter than 
N. mexicanum, and has the fine punctuation of the upper surface less extensive and 
the mentum differently formed. One specimen. 
8. Nosodendron championi, sp. n. (lab. XIX. figg. 26; 26a, sculpture of 
elytra.) 
Ovale, nigerrimum, nitidum, pedibus piceis, antennis testaceis ; thorace ad latera subtiliter punctato, elytris 
seriebus integris punctorum majorum et ad apicem reticulatis. 
Long. 33-34 millim, 
Hab. GUATEMALA, Chiacam in Vera Paz (Champion). 
In this species the series of elytral punctures are entire, each one extending from 
the base to the apex; on the apical portion the punctures become finer and each one 
is the centre of a peculiar network of fine punctures, as shown in the figure (fig. 26 a). 
This peculiar sculpture may be seen in some of the other members of the genus, but 
in none of them is it so highly developed as in WV. championi. ‘The head and thorax 
are distinctly punctate, but the disc of the latter is nearly smooth. The middle of 
the mentum is occupied by a large depression, in the centre of which there is a 
carina; the unimpressed lateral portions are small and finely punctate. The parts 
of the mouth are more hairy than usual. Fourteen specimens, exhibiting but little 
variation *. 
= I received a species closely allied to this in Castelnau’s collection of Cyclonotum; it may be the form 
referred to as Nosodendron cribratum, Fleutiaux & Sallé (Ann. Soc. Ent. Fr. 1889, p. 392), but is certainly 
not Cercyon cribratus, Cast., as they supposed, for the parts of the mouth cannot be scen, while Castelnau 
described them as visible in his species. This insect is 332 millim. long, allied to WV. championi, having the 
sutural series of punctures entire and the mentum with a large divided impression ; it differs from NV. cham- 
pioni by the entire absence of the hexagonal sculpture, which is replaced by a very minute punctuation, more 
dense at the tip of the elytra than elsewhere. Hab. Ayzittes, Guadeloupe. The species may be called 
N. cribratum, though it cannot be referred to Castelnau,
