NEMOTRICHUS. 353 
2. Nemotrichus armatus. (Tab. XII. figg. 28, 28a.) 
3. Nemotrichus armatus, Jordan, Nov. Zool. xi. p. 267. n. 52 (1904) '. 
Hab. Nicaragua, Chontales (Belt: 2); Costa Rica, San Carlos! (Schild-Burgdorf, 
3, in Mus. Tring). 
3. Nemotrichus teliger, sp. n. 
3 2. Very close to the preceding, perhaps only a geographical form of it. Buffish-grey pubescence much 
more restricted ; elytron irrorated with buffish-grey, generally with a conspicuous patch of grey behind 
the base and another before the apical declivity ; apical two-thirds of all tibia brown ; abdomen spotted 
with brown. Third interspace of elytron rather less elevate than in NV. armatus. Pygidium of ¢ almost 
evenly rounded, with a fine mesial carina apically which ends in a small point projecting beyond the 
apical margin ; fifth abdominal segment of ¢ convex, feebly truncate. In WV. armatus ¢ the pygidium 
is more triangular, subacuminate, and the fifth abdominal segment bears at the apex two impressions 
separated by a thin mesial carina. The pygidium of JV. teliger 9 is much less turned upwards at apex 
than in JV. armatus and more rounded. 
Length 4-8 millim. 
Hab. Panama, Volcan de Chiriqui, Bugaba (Champion). 
A series of each sex. 
4, Nemotrichus inermis, sp.n. (Tab. XII. fig. 29.) 
3 @. In colour resembling NV. armatus and JN. teliger ; pronotum more minutely dotted with luteous-grey, 
appearing almost black ; apical third of elytra and often also subbasal area more densely pubescent luteous- 
grey, middle of sutural area more uniformly brown, sometimes the elytra clay-colour, with a brown 
sutural spot and an antemedian lateral one. Frons wider. Tenth antennal segment rather shorter and 
less extended luteous ; first fore-tarsal segment less rufous beneath the grey pubescence ; tibie coloured 
as in WV. teliger. Pygidium of $ mucronate, ending in a prominent obtuse process, in 9 rather longer 
than in J. teliger and nearly as much turned upwards apically as in N. armatus. The abdomen of the 
3 is impressed, the rather deep impression being villose, especially on the last segment. Mid tibia of 3 
without apical spine. 
Length 43-63 millim. 
Hab. Mexico, Toxpam (Sallé); Nicaracua, Chontales (Belt, Janson); Panama, 
Bugaba, Volcan de Chiriqui [type] (Champion). 
Numerous examples. 
5. Nemotrichus spilotus, sp. n. (Tab. XII. fig. 30.) 
3d. Black, pubescent clay-colour, pubescence sparser beneath and greyer; four spots on occiput (the middle 
ones being small), some lateral spots on pronotum and five on disc, of these five two standing behind 
apical margin and two at base, whilst the fifth (which is lyre-shaped, but interrupted) is placed betore 
the carina, a small spot on basal callosity of elytron, two spots in and behind middle accompanied by 
some minute dots, a large patch of dots before apex, a small lateral spot at shoulder, a large one before 
middle and a small one behind middle of lateral margin, three spots on pygidium or two spots and a mesial 
vitta, and a row of rounded lateral spots on abdomen, black ; underside of tibie black, this colour occupying 
also apical third of fore tibia, forming a dorsally-interrupted basal ring on all tibia, and extending more 
or less on to upperside in apical third of mid and hind tibie ; tarsi brown, first segment pubescent grey ; 
last two segments of antenna luteous. 
Similar in shape to 1. burbicorns, F, (1801); lateral carina of prothorax shorter ; elytra more deeply striate ;
