HALEPOPEPLUS.—CILLAUS. 281 
Head short, the eyes placed some distance in front of the thorax, the surface rather 
closely and finely punctate. Thorax rather strongly transverse, convex, much rounded 
at the sides, the base sinuate-emarginate near the hind angles, the front a little 
emarginate, the front angles extremely obtuse, the surface polished, very shining, rather 
finely and closely punctulate. Scutellum very minutely punctate. Elytra with distant 
series of fine punctures, the series slightly irregular; the interstices sparingly and 
extremely minutely punctate. Hind body rather more distinctly punctate. Legs 
yellow; tibie strongly bidentate externally. Male with a conspicuous supplementary 
apical segment. 
2. Halepopeplus optatus, sp. n. (Tab. IX. fig. 5, 3.) 
Convexus, lete rufo-testaceus, elytris dimidio apicali nigro; politus, crebre subtiliter punctatus, elytris seriatim 
punctatis. 
Long. 32 millim. 
Hab. Nicaracua, Chontales (Janson). 
This pretty little insect differs from H. politus somewhat in colour and punctuation, 
and also in the more important characters of the shape of the prothorax and hind 
body ; the former has no trace of sinuation at the base or sides, these two parts being 
continuously rounded. The hind body is rather short, acuminate, densely and finely 
punctate. The basal part of the elytra is flavescent, and contrasts strongly with the 
black apical half. One male example. 
CILLAUS. 
Cilleus, Castelnau, Etudes ent. i. p. 133 (1835); Erichson, in Germar’s Zeitschr. iv. p. 247; Murray, 
Trans. Linn. Soc. xxiv. p. 311. 
This genus was established for some species from Madagascar; to these Erichson 
added one from Colombia, and Murray and Reitter have since described several other 
insects from South America as pertaining to it, but it is unknown in the United States. 
Mr. Champion states that these insects are found in the spathes of various Aroidew. 
1. Cilleeus prolixus, sp.n. (Tab. IX. fig. 3, 2.) 
Valde eclongatus, perdepressus, glaber, nitidus, subtilissime punctulatus, testaceus, elytris apicem versus abdo- 
mineque in medio fuscescentibus. 
Long. 54-8 millim. 
Hab. Guatemata, Sabo in Vera Paz (Champion); Panama, Bugaba (Champion). 
Head very finely punctulate. Thorax quadrate, quite truncate in front, the sides 
nearly straight, all the angles a little rounded, very finely punctulate. Elytra also very 
finely punctulate, nearly twice as long as the thorax. Hind body a little more distinctly 
punctulate, fuscescent along the middle. 
This insect cannot be confounded with any other of the genus owing to the 
BIOL. CENTR.-AMER., Coleopt., Vol. II. Pt. 1, October 1889. 2 O*
