punctate, the interstices flat and with the squamigerous spaces finely punctate. Beneath densely, finely 
punctate. Prosternum foveate behind the transverse subapical groove. Legs rather long and slender. 
Length 2,%,-3,, breadth 11-14 millim. (9.) 
Hab. Mexico, Chilpancingo and Amula in Guerrero 4600-6000 feet (H. H. Smith). 
Two females. Smaller than the same sex of G. albolineatus, the white scales on 
the elytra clustered into a common X%-shaped mark, the vestiture of the metasternum 
and abdomen finer, the apical portion of the rostrum flattened and less curved, the 
second joint of the funiculus more elongate. There are a few scattered white scales 
on the elytra beyond the post-median fascia. 
45. Gereeus tumidirostris, sp.n. (Tab. XV. figg. 18, 184, 3.) 
Oblong-rhomboidal, black, shining; the elytra with a line of scattered, oblong, white scales along each 
interstice (becoming double at the base and often in part abraded), the prothorax with a few hair-like 
smaller scales ; the under surface thickly, the legs more sparsely, albo-squamose. Head closely punctate, 
transversely depressed between the narrowly-separated eyes; rostrum long, curved, thickened and 
abruptly bent downward near the base (appearing gibbous when viewed in profile), coarsely punctate in 
the 3, the long apical portion flattened, more slender and almost smooth in the 9, the antennse inserted 
at (2) or a little beyond (¢) the middle, joints 1 and 2 of the funiculus elongate, 2 shorter than 1, the 
club ovate. Prothorax nearly as long as broad, narrow, conical, feebly constricted in front; densely, 
rather coarsely punctate, smooth along the median line. Elytra triangular, long, much wider than the 
prothorax, transversely depressed on the disc beyond the middle and also below the base, the suture also 
depressed anteriorly; deeply punctate-striate, the interstices almost flat and irregularly uniseriate- 
punctate. Beneath densely punctate. Prosternum narrowly sulcate. Anterior coxse narrowly separated. 
Legs rather elongate. 
¢. Prosternum armed with two moderately long porrect spines; first ventral segment slightly depressed 
down the middle. 
Length 44-53, breadth 24-25 millim. (¢ 9.) 
Hab. Guatemata, Sinanja and Sabo in Alta Vera Paz, Atlantic slope (Champion). 
Found in numbers at Sinanja. A peculiar form, with the upper surface shining, 
the under surface densely albo-squamose, the prothorax almost bare and conical, the 
elytra long, triangular, and clothed with scattered white scales, the rostrum thickened 
and gibbous at the base in both sexes. 
46, Gereeus scabripennis, sp. n. 
Oblong-rhomboidal, black, the prothorax shining, the rest of the surface duller; above very sparsely (elytra 
abraded), beneath thickly, clothed with white scales. Head closely punctate ; rostrum moderately long, 
slightly thickened towards the base, regularly arcuate throughout, coarsely punctate, smoother and 
widened at the tip, the antenne inserted at a little beyond the middle, the antennal club stout, oblong- 
ovate. Prothorax broader than long, conical, constricted in front; densely, finely, shallowly punctate, 
smoother and flattened on the disc towards the base, and with indications of a raised median line. 
Elytra triangular, long, much wider than the prothorax ; finely punctate-striate, the interstices flat and 
Beneath densely punctate. Prosternum narrowly suleate, armed with two very long 
densely rugulose. . t
