310 RH YNCHOPHORA. 
3. Discotenes cylindratus, sp. n. (Tab. X. fig. 14.) 
3 @. A small species, resembling in colour [schnocerus championi (p. 307). Black, rufescent; antenna black, 
or the shaft rufous; legs rufous or rufescent, apex of tibie and tarsi (except the base of the first segment) 
black, or, in pale specimens, brunnescent; pubescence grey beneath, clayish-grey above, not dense, 
variegated with brown on the upperside, suture and alternate interspaces of elytra whitish, dotted with 
brown or black, the dots often confluent in streaks, a dot in the middle of the third interspace mostly 
somewhat enlarged, often extended to the suture and to the fifth stripe of punctures. 
Rostrum broader than long, appearing slightly depressed mesially in g on account of the elevate upper edge 
of the large antennal grooves, flat in Q ; no distinct mesial carina. Antennal groove close to eye, but 
not touching it. Eye slightly transverse, the longest axis crossing occiput, not rostrum. Kighth antennal 
segment of about four times as long as broad; last segment of ¢ not longer than broad, irregularly 
rounded ; eighth segment proportionally narrower than in the preceding species. 
Prothorax as broad as long, rounded at the sides, not impressed on disc; a thin mesial line densely pubescent 
in good specimens. Elytra cylindrical, hardly depressed at the suture, distinctly punctate-striate, the 
strie all impressed, all the interspaces being a little convex; no tubercles; basal callosity vestigial. 
Fore tarsus longer than in the preceding species, especially in the ¢, the first segment being longer than half 
the tibia in both sexes. Abdominal segments 1, 2, and 3 of ¢ with a small, acute, mesial tubercle at 
apical edges. 
Length 43 millim. 
Hab. Mzxtco, Toxpam, Juquila (Sallé); Guaremata, San Gerénimo [type] and 
Tamahu in Vera Paz (Champion), La Tinta and Tucuru in Vera Paz (Conradt). 
4. Discotenes picticollis, sp.n. (Tab. X. figg. 15, 15a.) 
3d 2. Blackish-brown, rufescent; shaft of antenna and the legs rufous, middle of femora, three rings on tibia, 
and apices of tarsal segments more or less deep brown; pubescence beneath grey, above luteous or grey 
variegated with brown, black, and white; head and rostrum with an anteriorly forked grey-white line ; 
pronotum with a grey-white mesial line in front and a luteous one behind, central tuft blackish, four 
black oblique spots, two apical and two basal, bordered with luteous or grey ; scutellum white; suture of 
elytra and alternate interstices dotted with brown (or black) and grey, third interspace whitish-grey 
between the three tubercles, a transverse curved mark before apex of each elytron black, sutural angle 
greyish-white, tufts of tubercles brown or black, partly tawny; pygidium with the mesial line and sides 
grey; base of first tarsal segment slightly brownish. 
Rostrum short, broader than long, hardly dilated apically, depressed, mesially impressed, with a very thin 
carina in the impression, Antennal groove large, close to eye, but not touching it. Eye as in 
D. cylindratus. Club of antenna elongate; eighth segment of 2 as long as seventh, at least four times 
as long as apically wide, eleventh rounded in both sexes, not longer than broad. 
Prothorax as broad as long, almost evenly rounded at the sides in dorsal view, but being widest a little behind 
middle; a conspicuous mesial tubercle, with an oblique impression at each side, the impressions merged 
together into a deeper one in front of the carina. Elytra oblong, somewhat depressed, punctate-striate, 
each with three tubercles in the third interspace—one at base and another before subvertical apex high, 
the third in middle between them small, all tufted; the elytra transversely depressed behind the first 
tubercle. First fore tarsal segment rather less than half the length of the tibia. 
Length 4 millim. 
Hab. Guatemata, San Gerénimo, Cerro Zunil, Volcan de Atitlan (Champion) ; 
Panama, Bugaba [type] (Champion). 
A series.
