Rhypohius, founded on the North-Ainerictin R. maiinus, 

 Leconte, was oiiyiiiailj (but erroneously) de.'^cribed as having 

 y.jointed anteni.se. AJuroniUus was erectcl to contain the 

 European M. mjicollis^ Duval, and was correctly described 

 a.s iiaving the antennae of eleven joint*. In 1883 Leconte 

 and Horn [Olassif. CoL.N. Amer. (Sniithson. Misc. Coll. 

 xxvi.) p. 113] asserted that R/iy/zohius and Aforonillus are 

 really the same, and admitted that Leconte had wrongly 

 stated the number of antennal joints in his origitial descrip- 

 tion 0^ Rhypohius. Matthews also followed these writers in 

 regarding ALronillus as a synonym of Rhypohms (Mon. 

 Curyloph. p. 173). Ganglbauer, however (Kiif. JMitteleur. 

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

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

 tlierefore eni])loyed the name Aloronillus as distinct from 

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

 tenna of a specimen of R. marinus, Leconte, from Matthews's 

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

 that of R. oquilnms, sp. n. (tig. 38). Leconte and Horn and 

 Matthews were therefore right in regarding the number of 

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

 Moronillus. The character separating the two disappears, 

 and Moronillus must be treated as a synonym of Rhypohius. 

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

 cornis, Matth., also shows eleven joints. 



These remarks, however, do not apply to GIoBosoma, 

 "Wollaston. This genus was founded tor Glceosoma 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 antennae (an assertion which I am glad to be able to 

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

 Gloeosoma as a synonym of his genus Moronillus. To this 

 Wolla.ston replied in his ' Coleoptera Atlantidum ' (1865, 

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

 re-examined the type of G. 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
