708 RHYNCHOPHORA. 
Species very small, subovate, squamose and setose, with the rostrum arcuate, the eyes rather 
small, distant, the antennal club ovate, the prothorax transverse, subtruncate at the base, 
the scutellum minute, the elytra oval, truncate at the base, the mesosternum prominent, 
arcuate-emarginate, the metathoracic episterna rather broad, the ventral segment 2 as long 
as 8 and 4 united, the legs short, the femora unarmed. (No. 144.) 
144. Cryptorrhynchus scepticus, sp.n. (Lab. XXXV. figg. 4, 4a, 2.) 
Subovate, shining, piceous or rufo-piceous, thickly clothed with brown scales, the prothorax with five faint white 
lines (one median and two on each side), the elytra with an irregular humeral patch, a transverse median 
fascia, and some markings at the apex also white, and a fascia before the middle fuscous or blackish, the 
upper surface also set with short, erect, pallid and blackish, setiform scales, the blackish ones condensed 
into a small fascicle below the base of the third elytral interstice ; the legs with short whitish sete. 
Head densely punctate, the eyes rather small and widely separated ; rostrum stout, arcuate, not longer 
than the prothorax, widened towards the base, rugosely punctate to the tip in the ¢, much smoother in 
the 2, the antenns inserted at the middle, the club ovate. Prothorax transverse, rounded at the sides, 
narrowed and feebly constricted in front, subtruncate at the base; closely, rather finely punctate. 
Scutellum minute. Elytra a little wider than the prothorax, widening to about the basal third and 
rapidly narrowing thence to the apex, the humeri obtuse; punctate-striate, the interstices 3, 5, and 7 
somewhat convex, 3 swollen at the base. Beneath densely punctate. Mesosternum prominent, arcuate- 
emarginate. Legs short; femora unarmed. 
Length 33-33, breadth 13-1? millim. (¢ 9.) 
Hab. GvateMALA, Capetillo (Champion). 
One pair. This small species may be known by the almost straight base of the pro- 
thorax and elytra, the prothorax itself 5-lineate and the elytra slightly narrowed at the 
base, the minute scutellum, the unarmed femora, &c. It has the facies of an Acalles ; 
the metathoracic episterna, however, are well developed. The unarmed femora and the 
short third and fourth ventral segments separate C. scepticus from Heterobothrus. 
Species very small, oblong-ovate, densely squamose and coarsely setose, with the rostrum feebly 
arcuate, the eyes almost hidden in repose, the antennal club ovate, the elytra subtruncate at 
the base, the mesosternum U-shaped, the metathoracic episterna very narrow, the ventral 
segments 2—4 subequal in length, the femora unarmed. (No. 145.) 
145. Cryptorrhynchus insitivus, sp.n. (Tab. XX XV. figg. 5, 5a, 2.) 
Oblong-ovate, piceous, the antenne, and sometimes the tarsi and rostrum also, ferruginous ; variegated with a 
dense clothing of brown and whitish scales, the latter condensed on the elytra into an oblique humeral 
fascia and a large apical patch, the scutellum white; the upper surface also somewhat thickly set with 
coarse, erect, blunt, blackish sete, which are clustered into fascicles across the middle of the prothorax 
and along the alternate elytral interstices, the whitish apical patch limited above by clusters of very 
coarse, long, erect, whitish scales; the vestiture of the under surface and the base of the femora almost 
entirely whitish, the legs coarsely setose, the femora and tibie fusco-annulate. Head rugulosely punctate, the 
eyes widely separated, almost hidden in repose; rostrum short, stout, feebly curved, rugulosely punctate, 
bare and slightly widened at the tip, that of the Q smoother and less squamose, the antenne inserted 
beyond the middle, joint.2 of the funiculus shorter than 1, the club ovate. Prothorax rather broader 
than long, narrowed and constricted in front and also narrowed behind; densely punctate. Scutellum 
small, rounded. LElytra broader than the prothorax, subparallel in their basal third, subtruncate at 
the base, broadly produced at the apex; seriate-punctate, the interstices 3,5, and 7 raised. Beneath
