Cast., and there are several very similar uiiuamed forms fi'om Brazil 

 in the Museum. 



HOLOSTROPHUS Hoi'll 



The type of this genus is the N. American Ensfroplms bifasciatus 

 Say. Holof^trophns is repj-esented in Japan, Formosa, Sumatra, Borneo, 

 Java, the Philippines, &c. 



Xylita Payk. 



The type of Xylita is the holarctic Serropalpus laevigatus Hellenius 

 (^ X. biq^restoides Payk.). Specimens from the United States in the 

 British Museum, named by Horn, agree perfectly with others from 

 N. Europe, but Kirby's X. buprestoides from Canada (Fauna Boreali- 

 Americana, iv, p. 240), is a very different insect which I am vmable as 

 yet to identify. Serropa^nis barbatus Scliall. is another holarctic 

 insect. 



Carebaea Lee. 



Xylita parr ey SSI Muls. (= revelierei Muls. et Rey), from S. Europe, 

 belongs to this genus, and it is very closely related to the N. American 



C. longida. Leconte's name Carebara is pre-occupied by Westwood in 

 Formicidae, and the coleopterous genus was re-named JRushia by 

 Forel in 1893 ; Eeitter's name Xylitella (1911), therefore, falls as a 

 synonym. Fall described two additional N. American species under 

 Carebara in 1907. 



ZiLORA Muls. 



Seidlitz and Reitter both refer the Scotch insect recorded by 

 Sharp under the name Z. ferruginea Payk. to Z. sericea Sturm 

 (^ferruginea Muls. and etigeniae Granglb.). According to them, the 

 true ferruginea has more depressed eyes and the groove behind them 

 obliterated, &c. The few Continental examples of Z. eugeniae before 

 me have the prothorax much more coarsely punctured than in our 

 Scotch insect, but otherwise agree with it. Several N. American 

 Zilora are now known. 



DiRCAEA Fabr. 



I am unable at present to separate Dircaea from Fhloeotrya 

 Steph. D. dentato-niamdata and D. jiavitarsis Lewis, from Japan, 

 have a very sharply margined prothorax, and they may have to be 

 removed ; D. vitalisi Pic, from Cambodia, appears to be nearly 

 related to these insects. D. lignivora Lea, from W. Australia, = 



D. venusta Champ., from Tasmania, the latter name having a few months 

 priority. D. hohnbergi Mann. (1852), from Sitkha, is a Marolia and
