HYDROPHILIDA. 771 
Cercyon variegatus (p. 107). 
To the localities given, add :—Panama, Volcan de Chiriqui 4000 to 6000 feet (Cham- 
pion). 
9 (a). Cercyon alticola. 
Ovalis, sat convexus, testaceus, capite prothoraceque in medio nigris, antennarum clava fusca, palporum articulo 
ultimo nigricante ; elytris striatis, striis ad apicem vix profundioribus, interstitiis obsolete parce punctatis. 
Long. 2}-millim. 
Hab. Panama, Volcan de Chiriqui 8000 feet (Champion). 
Head and thorax with numerous rather large but extremely shallow punctures ; elytra 
striate, the strie not punctured, the interstices obsoletely punctured. 
On account of its colour this species resembles C. variegatus, but is narrower, with 
much finer striation of the elytra, and different punctuation on the head and thorax ; 
there is no trace of a lateral mark outside the medial black mark on the thorax. Four 
examples. 
PELOSOMA (p. 109). 
1(a). Pelosoma collare. 
Late ovale, sat convexum, rufescens, elytris nigricantibus, antennis palpisque pallide flavis; supra sat crebre 
subtiliter punctatum ; elytris subtiliter striatis, striis posterius parum profundius impressis. 
Long. 24, lat. 13 millim. 
Hab. Panama, Bugaba (Champion). 
Distinguished by the very delicate striation of the elytra, the striation consisting of 
series of punctures connected by extremely fine lines; the punctures of the three or four 
series near the suture are extremely fine, but those near the sides are larger; the 
marginal series is much sinuate or crooked near the base; the interstitial punctuation is 
scanty and very fine. The under surface is more or less picescent ; frequently the upper 
surface is entirely red. 
Numerous examples. According to Mr. Champion this insect and the allied species 
are found at the sap of trees. 
1(s). Pelosoma liodes. 
Subhemisphericum, nitidum, parce punctatum, fulvo-testaceum ; elytris striatis, striis posterius profundioribus. 
Long. 24, lat. 14 millim. 
Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion). 
Punctuation of the head and thorax rather distant but distinct. Internal strie of 
the elytra very fine at the base, but distinctly impressed at the extremity ; the interstitial 
punctuation very fine and distant. 
This is shorter in form than the other species of the genus, and is remarkable on 
account of the very scanty punctuation of the elytra. Three specimens.
