recognition. According to Leconte, the carina of the prothorax in his genus does 
not run dorsad before the middle. The tarsal claw of Acaronumus, Acarodes, and 
YXenorchestes bears a short, obtuse, subbasal tooth. 
1. Acaromimus sharpi, sp. n. (Acaropsis sharpi, Tab. XIV. figg. 31, 31 a.) 
Brownish-black, glossy, basal half of antenna rufous; legs pitchy, tarsi rufescent. Head sparsely pubescent- 
grey, rest of body glabrous. In shape similar to Acarodes gutta, Wollast. (1879), but more evenly 
rounded at sides from head to apex of elytra, the prothorax and elytra being wider at base than in 
Acarodes. Pronotum punctured, the punctures smaller than the interspaces, larger at sides and apex 
than posteriorly on disc. Elytra minutely punctured above, coarsely at the sides, the punctures more 
or less irregularly seriate, three rows of large punctures laterally at base more conspicuous than the 
others. 
Length 4 millim. 
Hab. British Honpuras, Belize (Blancaneauz). 
Two specimens. Named after Dr. D. Sharp, who, finding it among other small 
Coleoptera sent to him for study, correctly marked it “ Anthribid, near Acarodes.” 
XXXIX. HOLOSTILPNA, gen. nov. 
¢ 9. Glossy. Eye elliptical, vertical. Frons narrower behind than at the antennal grooves. Antenna 
reaching beyond base of prothorax, longer in g than in 2, segmeuts 1 and 2 thicker and longer than 
3 to 8, 3 as long as or shorter than 4, this shorter than 5, the following three gradually decreasing or 
equal in length, club very loose, segments asymmetrical, 9 and 10 triangular, 11 obliquely truncate- 
sinuate apically. Carina of pronotum not quite basal, flexed forward at sides, not reaching to middle ; 
basal carina distinct, laterally continuous with a longitudinal carina which, instead of joining the 
subbasal carina, runs parallel with it, the space between the two lateral carine impressed. Llytra ovate, 
widest behind base, basal edge of each somewhat convex, suture slightly elevate, Anterior legs much 
prolonged in d, less so in Q; first fore tarsal segment of ¢ nearly half the length of the fore tibia, 
somewhat curved, about one-third the length of the tibia in@. Tip of pygidium slightly turned up ind. 
Type: Choragus nitens, Lec. (1884), from the United States. 
1. Holostilpna glabra, sp. n. 
3. Resembling H. nitens, Lec. (1884). Antenna and legs black, feebly pitchy at the joints. Subbasal 
carina of prothorax forming an obtuse but distinct angle laterally and extending a little farther frontad 
at side than in H. nitens, not being shorter than the second lateral carina; the space between the two 
lateral carinze more deeply impressed. Elytra pitchy in middle, more finely seriate-punctate, the stripes 
less impressed, the punctures of stripes 2, 3, and 4 obsolescent at apex. 
Length 2 millim. 
Hab. Panama, Volcan de Chiriqui 5000 feet (Champion). 
One male. 
2. Holostilpna globosa, sp. n. 
Q. Shorter, broader, and more convex than H. nitens and H. glabra. Prothorax much more densely 
punctured above and below, widest at base, strongly narrowed from the apex of the lateral carine 
forward ; lateral angle of subbasal carina a little over 90°, being less obtuse than in H. glabra ; the two 
lateral carine of equal length, with the interspace impressed. Elytra much less angustate at base than
