BARIS. 461 
Boheman * as he supposed?, but a true Baris very nearly related to B. strenuwa, 
Lec., differing from that insect in its average smaller size and the non-costate sides 
of the elytral interstices. The smooth median line on the prothorax is usually very 
conspicuous. The intermediate and posterior tibie are sharply dilated at the outer 
apical angle. ‘The first ventral segment is deeply excavate down the middle in the 
male, as in the allied forms. Mr. Wickham has recently found B. sulcipennis in some 
abundance at Cuernavaca. Four specimens only were found in Guatemala, in the 
valley between the Volcanos Agua and Fuego. The examples before me measure: 
length 3-44, breadth 13-2 mm. 
6. Baris spissirostris, sp.n. (Tab. XXUI. figg. 1, 1a, 3-) 
Q. Oblong-ovate, shining, black or piceous, the tarsi ferruginous ; the punctures on the elytral interstices, 
under surface, and legs each bearing a small scale. Head sparsely, minutely punctate, shallowly, 
transversely grooved between the eyes; rostrum very stout, feebly curved, much shorter than the 
prothorax, closely punctate, slightly sinuate beneath (when viewed in profile). Prothorax transverse, 
feebly constricted in front; coarsely, very closely punctate, and with an abbreviated smooth median 
line. Scutellum strongly transverse. LElytra slightly wider than the prothorax, deeply punctate- 
striate, the interstices coarsely uniseriate-punctate throughout. Beneath closely punctate. Intermediate 
and posterior tibis acutely dentate at the outer apical angle. | 
Length 3-81, breadth 14-13 millim. 
Hab. Mexico (Mus. Brit.). 
Two females, one found by Truqui. Extremely like B. reqularis, but with a 
straighter, shorter, and much stouter rostrum, the prothorax slightly constricted in 
front, and the elytral interstices bearing larger squamules, the insect in this respect 
approaching B. sulcipennis, which, however, has a longer and more curved rostrum, a 
more coarsely punctured prothorax, Wc. 
7. Baris regularis, sp. n. 
3g. Oblong, rather convex, narrow, shining, nigro-piceous, the antenne, apical margin of the elytra, tip of 
the rostrum, and legs reddish; the punctures on the elytral interstices, under surface, and legs each 
bearing a minute scale. Head sparsely, minutely punctate, transversely grooved between the eyes; 
rostrum moderately stout, feebly arcuate, shorter than the prothorax, closely punctate. Prothorax 
transverse, rounded at the sides anteriorly, very closely, coarsely punctate, with or without an 
incomplete smooth median line. Soutellum small, strongly transverse, concave. Elytra considerably 
wider than the prothorax, deeply punctate-striate, the interstices rather narrow, flat, regularly and 
rather coarsely uniseriate-punctate throughout. Beneath closely punctate ; first ventral segment deeply 
excavate down the middle. Intermediate and posterior tibie sharply dentate at the outer apical angle. 
Length 22-24, breadth 1), milim. 
mos 
Hab. Mexico, Chilpancingo in Guerrero (HZ. H. Smith). 
Three males. Near B. sulcipennis, but much smaller, narrower, and more convex, 
the rostrum not so stout, the legs rufescent, the prothorax moderately coarsely punctate, 
the scales on the elytral interstices minute, the elytra appearing glabrous at first 
sight.
