Rhypoldua^ founded on the North-American R. marinusy 

 Leconte, was origiiiall}' (but erroneou.sl} ) de.'^cribed as having 

 y.jointed antenise. Moronillas was erected to contain the 

 European M. mjicollis, Duval, and was correctly described 

 a.s having the antennge of eleven joint*. In 1883 Leconte 

 and Horn [Classif. Col/. N. Amer. (Smith.son. Misc. Coll. 

 xxvi.) p. llii] asserted that R/iypobius and Morunillus are 

 really the same, and admitted tluit Leconte had wron^^iy 

 stated the number ot antennal joints in his original descrip- 

 tion o'i RJiy2)obias. Matthews also followed these writers in 

 regarding- Mironillus as a synonym of Rhypobius (Mon. 

 ('orylopit. p. 173). Ganglbauer, iiowever (Kaf. Mitteleur. 

 iii. 189y, p. 283, footnote), was not sati.stied that the number 

 of antennal joints is really the same in the two cases, and 

 tiierefore enij)loyed the name JSIoronitlus as distinct from 

 Rhypobius. I have made a balsam-preparation of the an- 

 tenna of a S])ecimen of R. marinus, Leconte, from Matthevvs's 

 Collection. It is undoubtedly 11-jointed, and closely resembles 

 that of R. aquilinus, sp. n. (fig. 38). Leconte and Horn and 

 Matthews were therefore right in regarding the number of 

 joints as the same in the type-species of Rhypobius and 

 Moromllus. The character separating the two disappears, 

 and MoroniUus must be treated as a synonym of Rhypobius, 

 A preparation of the antenna of the West-Indian R. brevi- 

 cornis, Matth., also shows eleven joints. 



These remarks, however, do not apply to Glwosoma, 

 "Wollaston. This genus was "founded tor Gloiosoma velox, 

 "Woll., which was described from a unique example found in 

 Madeira, but of which other examples, subsequently taken 

 in North Africa, are also to be seen in the British Museum. 

 Wollaston described and figured the genus as having 10- 

 jointed antennffi (an assertion which I am glad to be able to 

 confirm, below). But Duval, in his Gen. Col. Europe, sank 

 Gloeosoina as a synonym of his genus Moronillas. To this 

 WoUa.ston replied in his ' Coleoptera Atlantidum^ (1865, 

 pp. 93-5, and footnotes), saying that he had carefully 

 re-examined the type of (J. velox, and was convinced that his 

 original figure and description were correct, that the antennse 

 were really 10-jointed, and that the joints differed in form
