Mr. Wickham has sent us a long series of this common N.-American species from 
Mexico, one of them with the subsutural apical spots distinct, one with the dark spots 
extending on to the disc, and the rest with the vestiture of the elytra uniformly 
ochraceous or whitish, as described by Uhler. The two females from Amula doubtfully 
referred to G. sinuatipes (anted, p. 276) also belong here. G. penicellus has the 
prosternum unarmed in the male, but otherwise it is very like many of the species 
placed under “04” in the Table. The closely related G. ¢onsilis has a stouter rostrum, 
non-unguiculate anterior tibiz in the male, &c. 
80 (a). Gerzeus tenuistriatus, sp.n. (Lab. XXIII. figg. 253, 23a, 2.) 
Oblong-rhomboidal, flattened above, black; densely clothed with small adpressed white scales—those on the 
prothorax long, narrow, and transversely arranged, those on the elytra oblong-oval and placed in four 
compact rows along each interstice (the first with three rows only), and those on the under surface 
rather broad and oval,—the scutellum and humeral callosities bare. Head densely punctate, squamose ; 
rostrum arcuate, about twice as long as the prothorax, slender, very slightly thickened at the base (as 
seen in profile), flattened and widened towards the tip, finely punctate and feebly carinate in its basal 
half, the apical portion almost smooth, the antenni inserted at the middle. Prothorax strongly 
transverse, conical ; densely, very finely punctate. Scutellum subquadrate, rather large. Elytra much 
wider than the prothorax, rather long, subtriangular, the humeri rather prominent; very finely and 
shallowly punctate-striate, the interstices broad, flat, and densely rugulose. Beneath densely punctate. 
Prosternum shallowly sulcate. 
Length 44, breadth 2,4; milim. (@.) 
Hab. Mexico (ex coll. Solari). 
One female, in bad condition. Closely related to G. candidus, but more flattened 
above, the rostrum longer and quite slender throughout, the antenne inserted at 
the middle, the elytral strie very fine, shallow, and inconspicuous, the prothorax 
rapidly and obliquely narrowing from the base. he faintly striate elytra and 
the long, slender rostrum separate (. tenwistriatus from all the other Mexican species 
of the genus.
