CHARISIUS.—NARSES. 42 
Os 
Hab. Mexico, Jalapa (Hoge). 
Numerous examples. This insect differs constantly from C. zunilensis in the above 
particulars, and I have no doubt that it is a good species; both bear a certain resem- 
blance to the genus Talanus. 
4. Charisius salvini. (Tab. XIX. fig. 15, 3.) 
Elongate, rather narrow, convex, subparallel, reddish-brown, the prothorax and the extreme apex of the elytra 
sometimes stained with piceous, shining. Head somewhat coarsely and rather closely punctured, a narrow 
longitudinal space between the eyes usually impunctate; antenne rather stout, especially in the female ; 
prothorax convex, rather broader than long, widest at the middle, the sides rounded, a little sinuate 
behind, and almost straight at the base, the hind angles rectangular, the dise shallowly canaliculate, the 
transverse basal groove rather deep, the basal foves shallow, the surface coarsely and rather closely punc- 
tured ; elytra moderately long, with coarsely and closely punctured rather deep strie, the sutural stria 
moderately deep, the interstices smooth and somewhat convex, more strongly so behind; beneath finely 
and sparsely punctured, the metasternum and the prothorax very coarsely so at the sides, the former rather 
shallowly canaliculate behind; legs and antenne fusco-ferruginous or brownish-piceous. 
3. Anterior tibize very feebly widened on the inner side about the middle. Fifth ventral segment semicircu- 
larly excavate in the middle at the apex. The lateral lobes of the last ventral segment spatulate in shape, 
the apex broad and obliquely cut off; the central sheath gradually narrowing, the apical portion recurved 
upwards, the apex slightly hooked. 
Length 9-10 millim.; breadth 24-3 millim. (¢ 9.) 
Hab. Guatemata, near the city, Chinautla (Salvin), Duefias (Salvin, Champion), 
Capetillo, Calderas, Cerro Zunil (Champion). 
Var. The elytra each with a small spot at the middle of the disc, two smaller ones towards the apex (one on 
the lateral margin and one near the suture, placed transversely), and the apex, black. 
Hab. GuatEeMALa, Panajachel (Champion). 
Numerous examples of the typical form, one only of the variety. Broader than 
C. zunilensis, the thorax more rounded at the sides and much more coarsely punctured, 
the striz of the elytra more coarsely punctured, the sutural stria not so deeply im- 
pressed, &c. 
NARSES. 
Oral organs and head much as in Charisius; the eyes somewhat rounded and widely separated in both sexes ; 
antenne very long and slender, the joints obconic; prothorax subcylindrical, as long as broad, without 
well-defined transverse basilar groove, the base almost straight; scutellum transverse, moderately large ; 
elytra ovate in shape, the base truncate and wider than the prothorax, the humeri more abrupt and less 
rounded than in Charisius, the sutural stria not deeply impressed; legs, including the tarsi, as in 
Charisius, but with much stouter femora; metasternum very short, deeply notched in the middle behind 
for the reception of the intercoxal process, the latter subtriangular and transversely convex; body 
glabrous, elongate ovate; wings small and not adapted for flying. 
A single species from Guatemala, differing from Charistus in the above particulars ; 
N. subalatus might perhaps be regarded as a subapterous form of that genus, but I have 
thought it advisable to separate it. The tarsi are broadly lobed beneath in both sexes,
