558 RHYNCHOPHORA. 
04, Eubulus biangularis. (Tab. XXVII. figg. 24, 244, ¢.) 
Cryptorhynchus biangularis, Ros. in Schénh. Gen. Cure. iv. p. 163°. 
Celosternus biangularis, Boh. op. cit. viii. 1, p. 370 *, 
Hab. Mexico2, Vera Cruz (Chevrolat '), Orizaba (Sallé); Guatemata, El Tumbador 
and El Reposo, Pacific slope (Champion) ; Nicaragua, Chontales (Richardson). 
Seven specimens, agreeing with the type communicated by Dr. Sjéstedt. Recog- 
nizable by its rhomboidal form, the faint oblique whitish streak on each elytron, the 
narrow, cylindrical, curved rostrum, the long legs, the elongate basal joint of the 
posterior tarsi (this being more elongate than in the following species), and the almost 
smooth second ventral segment, the sides only of the latter being punctured. The 
first three joints of the funiculus are elongate. The short second ventral segment is 
narrowly produced on each side behind, and there nearly reaches the apex of the 
third, much as in EL. triangularvs. 
25. Eubulus ineequalis, sp. n. 
Cryptorhynchus inequalis, Chevr. in litt. 
Rhomboidal, black, the antenne ferruginous ; somewhat thickly clothed with rather coarse, intermixed fulvous 
and whitish scales, which are more or less distinctly clustered into an oblique fascia before the middle of 
each elytron and a faint annulus on the femora. Head rugosely punctate, sulcate on each side between 
the eyes, which are very large and somewhat narrowly separated; rostrum rather slender, curved, 
reaching the front of the metasternum, closely punctate and carinate at the base and minutely punctate 
thence to the tip, the antenne inserted at the middle, joints 1 and 2 of the funiculus subequal in length, 
the club ovate. Prothorax strongly transverse, subconical, the sides very feebly rounded and forming an 
almost continuous outline with those of the elytra; densely, confluently, moderately coarsely punctate 
and also carinate. Scutellum oblong, smooth. Elytra subtriangular, produced at the apex, the humeri 
rounded; punctate-striate, the interstices rugulose, 3,5, 7, and 9 sharply costate. Ventral segments 
coarsely punctate ; 2 with a single transverse row of punctures before the middle, smooth behind. Legs 
moderately long; femora unidentate, and also armed with a small denticle exteriorly ; posterior tarsi 
with the basal joint as long as 2-4 united. 
Length 53-74, breadth 24-33 millim. (.) 
Hab. Mexico, Matamoros Izucar, Puebla (Sallé) ; Nrcaracua, Chontales (Janson). 
Four specimens, all but one from Mexico. Very like #. biangularis, but with the 
basal joint of the hind tarsi shorter and the second ventral segment with a row of very 
coarse punctures before the middle. A single example of each species has been 
received from Chontales. 
96. Eubulus trigonalis, sp.n. (Tab. XXVII. figg. 25,.254, 2.) 
Oblong-rhomboidal, nigro-piceous or black, the antennex ferruginous ; mottled above and beneath with a rather 
dense clothing of intermixed fulvous (or ochreous) and whitish scales, which in fresh specimens are 
clustered into a spot on the median lobe of the prothorax and an interrupted oblique streak on each side 
of its disc, Head rugosely punctate, sulcate on each side between the eyes, which are separated by a 
little less than the width of the rostrum ; rostrum rugosely punctate and carinate to near the middle and 
sparsely punctate thence to the apex, the apical half smoother in the 2, joints 1-3 of the funiculus
