for a single species, unknown to tlie author, but characterize'! 

 hy the j)ossessi()n of tarsi with only four joints, a phenomenon 

 unknown in any other IjanicUicorn beetle. Uofonin;^ to the 

 original description by Frietlenreich of this anoujaiou.s beetle, 

 in the ' Stfttiner entomologische Zcitschritt' for 1883 

 (p. 375), I was glad to find not only the beetle but also its 

 larva described in detail. Many of the characteri.sticH of 

 both, however, are such that I have no hesitation in rejecting 

 the insect, not onlv frcjin the Trogida*, but from the Lamelli- 

 corn suborder. Ih/ildphi/fia fungicola, Fried., is a minute 

 beetle found in fungi in Brazil. It is 2i mm. long, and has 

 anteniiie of II joints, of which 7 are lamellate. The right 

 mandible is simple and acutely jiointed, while the left is 

 strongly bifid. These, as W(dl as its other structural features, 

 unmistakably identify it with the genus liJu'indanilrus^ 

 Leconte {Eutomus, Lacordaire), belonging to tho Malaco- 

 derinatous family Cioidaj. The species hitherto placed in this 

 genus range from the United States of America to the northern 

 part of (South America, and Friedenreich's insect may be 

 regarded as another species extending this range farther 

 southward. The genus was characterized by Lacordaire 

 under the name of Eutomus in 1866 ; but Lcconte's name, 

 although stated by Fleutiaux and Salle to be of later date, 

 was really published by him in 18G2 in part 1 of his ' Classifi- 

 cation of the Coleoptera of North America' (p. 236). The 

 claim of the name lihiiiiddndrus over the other two is there- 

 fore indisputable. A second genus, Cherostus, has been 

 treated by Mr. AVaterhouse for two Old- World forms very 

 nearly related to the American insects. They have the 

 laniellaj of the antennal club much shorter, and all the libiaj 

 are armed with sjjines at their ends. Lacordaire's species, 

 lihijiidaiulrus micrographus, which was described from 

 northern South America, has been recorded from Guaileloiipc 

 and St. Vincent. I have seen no sjjecimens from the former 

 island, but those from the latter, which are in the British 

 Aluseum, do not agree with Lacordaire's description, all the 

 tibiae having spinose prolongations, while the antennae have 

 the first joint quite short, instead of reaching to the middle of 

 the eye, and the lamelias quite short. It therefore agrees 

 better with Cherostus, and 1 propose to call it
