GRAPHONOTUWS. 609 
specimens enclosing some dark sutural spots); the upper surface and legs also with a few scattered, very 
short, decumbent, setiform scales. Head rugosely punctate and feebly carinate, usually foveate between 
the rather narrowly separated eyes; rostrum long, rugosely punctate and 5-carinate at the base, and very 
finely, sparsely punctate from the middle to the apex, smoother in the 2, the antenne inserted slightly 
behind the middle, joint 2 of the funiculus longer than 1, the club ovate. Prothorax broader than long, 
constricted and much narrowed in front ; sparsely granulate, each granule preceded by a small puncture, 
the interspaces minutely punctate, the disc finely carinate. Elytra seriate-punctate and granulate, the 
interstices also punctulate, the marginal one (8) raised and serrulate. The sides of the metasternum 
coarsely, and the ventral segments obsoletely, punctate. Rostral canal almost or quite reaching the 
front of the metasternum. Femora clavate, and each with a rather broad triangular tooth, the anterior 
pair similar in the two sexes. Anterior tibize not elongated in the ¢. 
Length 8-11, breadth 33-53 millim. (¢ 2.) 
Hab. Guatemata, Senahu in Vera Paz (Champion); Nicaraeua, Chontales (Beit, 
Janson); Costa Rica, Cariblanco, Sarapiqui (Lankester), Coronel (Biolley); Panama, 
Bugaba, Volcan de Chiriqui (Champion).—Cotoms1a (Mus. Brit.). 
A common insect in Chiriqui, and distributed in collections under the above-quoted 
MS. name. It is a close ally of G. albocaudatus (Ros.), differing from it in the form 
of the apical patch (which is always interrupted at the sides and excised in front), the 
broader femoral tooth (especially noticeable on the anterior pair), the simple anterior 
tibie of the male, the longer rostrum, &c. 
3. Graphonotus bituberculatus, sp n. (Tab. XXX. figg. 3, 3a, 3.) 
Oblong-ovate, black; mottled above with small fulvous, cinereous, and black scales, the black scales condensed 
into an angulate, anteriorly evanescent, median fascia on the elytra and a small spot on each of the 
tubercles near the base, and the others into a large, anteriorly excised, apical patch, which encloses some 
dark markings at or near the suture towards the tip; the elytra also with a few very short, scattered, 
decumbent setiform scales. Head rugosely punctate; rostrum moderately long, rugosely punctate and 
carinate in its basal half, and sparsely, finely punctate thence to the tip, smoother in the 9, the antennee 
inserted beyond the middle in the g, and at about midway in the @, joints 1 and 2 of the funiculus 
subequal in length, the club ovate, acuminate. Prothorax transverse, rounded at the sides, constricted 
and much narrowed in front; somewhat closely granulate and also carinate. Elytra parallel at the 
base, flattened along the suture anteriorly ; seriate-punctate and also granulate, the interstices 5-9 
subcarinate, 3 with a tuberculiform prominence below the base. The sides of the metasternum coarsely, 
and the ventral segments finely, punctate. Rostral canal nearly reaching the metasternum. Femora 
clavate, acutely unidentate. Anterior tibie not elongated in the ¢. 
Length 52-9, breadth 22-4 millim. (¢ 2.) 
Hab. GuateMALA, Cerro Zunil, Senahu (Champion); Costa Rica, Monte Redondo 
(Tristan, ex Biolley); Panama, Volcan de Chiriqui (Champion).—Amazons (Mus. 
Brit.). 
Ten specimens, varying greatly in size. Very like G@. leporinus, but with the elytra 
bituberculate near the base, the antenne inserted nearer the tip of the rostrum (which 
is rather shorter), the pale apical patch uninterrupted laterally, the femoral tooth 
acute, the prothorax more rounded at the sides.
