interstices more even, and the humeri less prominent, the prothorax more ample, &c. 
More oblong than B. fratruelis, the elytra relatively narrower and with flatter 
interstices; narrower than B. rotundicollis, the prothorax less rounded at the 
sides, &c. 
22. Baris caldaria, (Tab. XXIII. figg. 6, 6a, ¢.) 
Baridius caldarius, Boh. in Schénh. Gen. Cure. viii. 1, p. 142°, 
Hab. Mexico (coll. Germar!; Trugui, in Mus. Brit.). 
The insect sent me from Stockholm as the type of B. caldaria (like the specimen 
representing it in the British Museum) does not accord very well with Boheman’s 
description, and the identification of the four examples here referred to the species is 
doubtful. They are move elongate and slightly larger than B. corrusca (instead of 
being “dimidio minor”); the prothorax is more rounded and somewhat ampliate at 
the sides anteriorly, and has a well-defined smooth median line; the elytral interstices 
are Closely and finely uniseriate-punctate, the second confusedly punctured; and the 
rostrum is distinctly longer. 
23. Baris implana, sp. n. 
Oblong-ovate, narrow in the ¢, broader in the 2, very shining, eneous, the legs rufo-piceous or reddish ; 
almost glabrous above, the punctures on the under surface and legs each bearing a minute scale. Head 
minutely punctate, transversely grooved between the eyes ; rostrum strongly arcuate, short, moderately 
stout, very finely, sparsely punctate. Prothorax transverse, gradually narrowing from the base, feebly 
constricted in front; somewhat closely punctate, with or without a smooth abbreviated median line. 
Scutellum very small, rounded. Elytra wider than the prothorax, gradually narrowing from the rounded 
humeri, undulate, depressed along the suture from near the base; finely, sharply striate, the striz: 
sometimes distinctly punctate, the interstices broad, flat, narrowly costate at the apex, each with a row 
of scattered very minute punctures. Beneath rather sparsely punctate; metasternum and first ventral 
segment hollowed in the middle in the ¢. Tibiw almost straight. 
Length 23-32, breadth 11-13 millim. (¢ 9 .) 
Hab. Mexico, Jalapa (Hoge: ¢ 2), Jacale, Juquila (Sailé: ¢ ). 
Five specimens, the female from Juquila with the strie and outer interstices some- 
what strongly punctured. A form of B. wrea, with strongly undulate, finely striate 
elytra, the first (sutural) stria somewhat deeply impressed, the interstices faintly 
uniseriate-punctate ; the male narrow, the female broader. ‘The elytral interstices are 
narrowly costate at the apex, much as in Pseudobaris acutipennis and its allies. 
24. Baris fratruelis, sp. n. 
Oblong-ovate, somewhat flattened above, very finely alutaceous, shining, eneous, the legs sometimes reddish ; 
almost glabrous above, the punctures on the under surface and legs each bearing a minute scale. Head 
finely punctate, transversely grooved between the eyes; rostrum stout, arcuate, very short, closely 
punctate. Prothorax transverse, rounded at the sides anteriorly ; closely punctate, with indications of a 
smooth abbreviated median line, Scutellum small, transyerse. Elytra broader than the prothorax,
