422 HETEROMERA. 
é. 
or testaceous, the light markings more or less surrounded by prownish-black. Head sparsely and finely 
punctured, the vertex smoother and shallowly longitudinally impressed in the middle ; prothorax narrowing 
anteriorly from the middle, the sides a little sinuate behind, the hind angles rather obtuse, the dise deeply 
canaliculate before the base and apex and somewhat flattened, the transverse basal groove and the basal 
foves very deep, the surface very finely and remotely punctured ; elytra very long, widest beyond the 
middle, the apices somewhat broadly produced, with rows of rather fine approximate punctures placed 
upon shallow strie, the interstices impunctate, flat at the extreme base, and thence gradually becoming 
more convex, and at the apex subangularly raised ; beneath reddish-brown, the metasternum very long, 
shallowly canaliculate, and very finely and sparsely punctured in the middle and coarsely so at the sides, 
the ventral surface almost smooth, the apical margin of the fourth segment with a row of punctures, the 
fifth ventral segment unimpressed in both sexes; legs and antenne varying in colour from ferruginous to 
brownish-black. 
Anterior tibie slightly widened on the inner side before the middle. The lateral lobes of the last ventral 
segment strongly curved, narrow, and somewhat spatulate in shape; the central sheath acuminate, the 
apex slightly rounded. (Fig. 12 a.) 
Length 104-124 millim.; breadth 33-4 millim. (d 2.) 
Hab. Guaremata, Totonicapam 8500-10,500 feet, Quiche Mountains 9000 feet 
(Champion). 
Var. The discoidal spot on the elytra obsolete. (Fig. 13.) 
Hab. Guatemaa, Cerro Zunil 5000 feet, Calderas 6000 feet (Champion). 
Eight examples, five of the typical form and three of the variety. 
2. Charisius zunilensis. (Tab. XIX. fig. 14, ¢.) 
Elongate, rather narrow, subcylindrical, reddish-brown, the prothorax and the basal half of the elytra sometimes 
3. 
stained with piceous, shining. Head closely and finely punctured; prothorax subcylindrical, about as 
long as broad, the sides narrowing a little anteriorly and rounded at the apex, and almost straight or 
feebly sinuate behind, the disc canaliculate (shallowly in front but very deeply so before the base), the 
transverse basal groove moderately deep, the basal foveee shallow, the surface finely and closely punctured ; 
elytra long, parallel in their basal half, deeply striate, the striee with closely-placed rather coarse punctures 
which become much finer towards the apex, the sutural stria very deep, the interstices smooth and mode- 
rately convex ; beneath very finely and sparsely punctured, the metasternum with coarse impressions at the 
sides and deeply canaliculate in the middle behind, the ventral surface still more finely punctured and 
with very shallow longitudinal wrinkles, the fifth ventral segment unimpressed in both sexes; legs and 
antenne ferruginous, the femora sometimes a little darker. 
Anterior tibia as in the female. The lateral lobes of the last ventral segment slightly curved and 
spoon-shaped ; the central sheath acuminate, the apical portion subparallel and with the apex rounded. 
Length 84-9 millim.; breadth 23-24 millim. (3 9.) 
Hab. Guatemata, Cerro Zunil 4000-5000 feet (Champion). 
Six examples. 
3. Charisius interstitialis. 
Closely resembling C. zwnilensis, and differing as follows :—Shorter and less cylindrical ; the prothorax shorter 
(not so long as broad), and rather more closely punctured ; the elytra shorter, less convex, the interstices 
more convex and finely but distinctly punctured; the rest as in C. zunilensis. 
3. Anterior tibiz as in the female. The lateral lobes of the last ventral segment spoon-shaped ; the central 
sheath acuminate. 
Length 63-73 millim.; breadth 23-23 millim. (¢ 9.)
