In Botrodus the fifth and sixth joints of the antennae are ap- 

 parenth" slightl}- dilated. The t3^pe and onl}- species of Mycho- 

 cerus known to me is 31. depressus Lee, which occurs rarely in 

 the District of Columbia and in Ohio. Bott^odus estriatus Cs}'. 

 occurs in Texas. The species recently described from Mexico 

 by Mr. Lewis I have not seen. 



MURMIDIINI. 



The small and possibh' cosmopolitan species known under the 

 name Murmidius ovalis Beck., difiers profoundl}- from the two 

 preceding genera in a number of structural features, and demands 

 a distinct tribe. The presternum has two strongl}^ elevated par- 

 allel lines not attaining the apex, the anterior lobe being very 

 large, rounded, evenlj^ continuous with the sides of the prothorax 

 and completely concealing all the mouth parts and labrum in re- 

 pose ; intercoxal process short and broad, extending under the 

 broad and advanced mesosternal process. Antennal cavities small, 

 deep, apical, superior and completel}^ visible only from above. 

 Epistoma very large, the suture fine. Legs stronglj^ retractile, 

 the epipleurffi with a deep crural excavation at base and another 

 near the middle. Met-episterna extremeh" narrow but not con- 

 cealed by the epipleurse, the suture ver}' fine and feeble. El3tra 

 seriately punctate. 



I am unable to observe the labrum, trophi or antennae in the 

 three specimens in my cabinet. 



EUPSILOBIINI. 



The general characters of this tribe are included in the follow- 

 ing description of the only genus thus far discovered : — 



El PSILOBIUS n. gen. 

 Body almost evenly elliptical and stronglv convex, the eh'tra 

 devoid of punctured series, the scutellum small but distinct, 

 transverse and broadl}' rounded behind ; edges of the pronotum 

 acute and subvertical, with the marginal bead extremely fine and 

 flat, the h3^pomera beneath broadly concave. Maxillary palpi 

 with the fourth joint long, C3dindrical, obtusely pointed, as wide 

 as the third and longer than the three basal joints combined ; 

 labial palpi shorter but much stouter, the second joint transverse, 

 the third broad, oval and compressed. Ligula large, broad, cor-
