312 Mr. D. Sharp's revision of the 



sculptured, and the elevation on the front of the head is 

 much broader ; the elevation on the basal ventral seg- 

 ment is conspicuous, and the tubercles on the apical 

 segment, instead of being near the base, are near the 

 extremity. 



Batrisus ornatus, Sharp. 



Sharp, Trans. Ent. Soc. Lond., 1874, p. 114. 



A few additional specimens of this species were found 

 about Nagasaki in March and April, 1881, and single 

 specimens, which are probably females of the species, 

 occurred also at Nikko and Yanoshiku in the autumn 

 of the year, as well as one at Bukenji, near Yokohama. 



Batrisus basicornis, n. s. 



Angustulus, rufescens, evidenter pubescens, antennis 

 sat validis ; vertice impunctato, subtiliter carinato, 

 tuberculis antennalibus latis, dense punctatis, fronte 

 medio depressiusculo ; prothorace medio canaliculato, 

 utrinque breviter carinulata, cannula posterius tenuiter 

 spinosa, ad latera impressa, fere impunctata ; elytris 

 plicula discoidali abbreviata, basi minute sex-foveolatis ; 

 abdomine segmento dorsali basali sequentibus duobus 

 sequali ; tibiis posticis calcari apicali longo. Long. 

 2^ mm. 



Mas, antennarum articulo basali valde dilato-laminato, 

 facie anteriore producto, densius glanduloso-granulato, 

 tuberculis antennalibus latis prominulis ; clypeo pro- 

 cessu transverso superne in elevationem tenuem pro- 

 longate : trochanteribus intermediis angulato-promi- 

 nulis ; segmento ventrali apicali in medio tuberculis 

 elongatis, prominulis. 



The male of this species is readily distinguished by 

 the great development of the basal joint of the antennae 

 and the different form of the ornament on the clypeus ; 

 the female is apparently only to be distinguished from 

 the corresponding sex of B. ornatus by the considerably 

 greater breadth of the process of the head that separates 

 the insertion of the antennae. 



Three specimens were found at Miyanoshita in April 

 and May, 1880.
