MR. A. MURRAY’S MONOGRAPH OF THE FAMILY OF NITIDULARLE. 337 
7. CoNoTELUS MEXICANUS. 
C. vicino affinis; differt thorace rugoso et haud punctato, pedibus nigris. Long. 14 lin., 
lat: $ lm ^ 
Habitat in Mexico. 
Closely allied to C. vicinus ; and as C. femoralis and C. vicinus are very closely allied to 
each other in Columbia, so are C. rufipes and C. Mexicanus in Mexico, where they take 
their place. Smaller than C. vicinus; less shining and of a less clear black, it being 
rather a dull, very slightly brownish, black. Head, thorax, and elytra opaque, instead 
of being somewhat shining as is the case in C. vicinus. The thorax instead of being 
finely punctate is finely confluently rugose like morocco-leather. The elytra have very 
slight traces of a linear arrangement of its rugosities. The abdomen is somewhat shining 
and finely and sparsely punctate; fimbriz broader than in C. vicinus. Legs black. 
Collected by M. Sallé in Mexico. 
8. CoNOTELUS SUBSTRIATUS. 
Erichs. in Germ. Zeitschr. iv. 253 (1843). 
C. nitidus (Motsch.). 
Niger, nitidus, punctulatus, elytris subtiliter punctato-striatis, interstitiis punctulatis ; 
pedibus piceis. Long. 1$ lin., lat. 3 lin. 
- Habitat in Columbia et America centrali. 
Black, shining. Antenne testaceous, with the first article and the club piceous. Head 
very closely punctulate, bifoveolate in front. Thorax closely punctate, with the sides 
very faintly rugulose. Scutellum very faintly and obsoletely punctulated, with the apex 
rounded. Elytra faintly and neatly punctate-striate, the striæ becoming obsolete at the 
apex, the interstices flat, very faintly punctulate. Abdomen sparingly and obsoletely 
faintly punctulate. Legs piceous, knees and tarsi testaceous. 
From Columbia. 
9. CoNOTELUS NITIDUS. 
C. substriato affinis : niger, nitidus, sparsim et sat fortiter punctatus, convexus; thorace 
brevi, transverso, longitudine latiore; scutello transverso, truncato; elytris striato- 
punctatis, fortius et minus regulariter quam in C. substriato, interstitiis sparsim 
punctatis ; abdominis segmentis brevibus; pedibus piceis. Long. 1} lin., lat. 2 lin. 
Habitat in Brasilia. 
Black, shining, shorter than most of the others, convex, with the sides rounded; 
covered sparingly with distinct punetures. "Thorax short, transverse, broader than long; 
base rounded, angles rounded and obtuse. Seutellum transverse, truncate. Elytra 
with irregular and interrupted rows of punetures, deeper but more interrupted than in 
C. substriatus ; the interstices with an occasional puncture forming a widely scattered 
row, and with a great accumulation of punetures near the base; an elongate impres- 
sion on each side of the suture towards its base. The exposed segments of the abdomen
