derided, they are diurual, and in Japan they display the greatest 

 activity in sunny warm days of May and June ; but in the tropics I 

 imagine they are on the alert whenever the weather is fine, but not in 

 the extreme heat of noon. They are not always easy to catch, as they 

 drop and fly when disturbed. 



Elacatis Keaatzi, Eeitter, Deutsche Ent. Zeit., 1879, p. 22G. 



This species varies very much in size, my largest $ measures 62 mm., and the 

 smallest ? 3^ mm. I took very few males in comparison with the number of 

 females, and the males have two curious fovese in the middle of the mentum, each 

 fovea having a tuft of protruding griseous hairs. Dr. Horn first published a notice 

 of this sexual character, and figured it in the Trans. Am. Ent. Soc, 1888, p. 28, t. 3, 

 fig. 24 b, after having seen it in an American species. In E. Kraatzi it is very con- 

 spicuous, and as Reitter has not seen it, I think he only knew the female. The 

 female has only two shallow impressions in the menton. 



Sah. : Eound in all the Japanese islands in forests away from 

 the coast. 



Eeitter described this species from a Siberian specimen, and a 

 type from Herr Eeitter kindly sent to me agrees exactly with my .? 

 specimens. 



I also found the following in South Japan. 



Elacatis ocularis, n. sp. 



Angustata, suhparallela, nigra, griseo-puhescens, punctata, sat nitida ; 

 antennis nigris, genicuUs tarsisquc ferrugineis ; fronte incequali, oculis promi- 

 nentibus; thorace undique suhocellato-punctato, utrinquc 4,-denticuIafo; elytris 

 punctatis maculis plurimis irroratis luteis. Long., 3^ — 4 mm. 



Narrow, rather parallel, black, clothed with griseous pubescence ; antenna; 

 black, in two examples piceous, but in all concolorous, Ist robust, 2nd similar in 

 shape but smaller, 3rd longer and less stout, 4th to 8th raoniliform, 9th and 10th 

 transverse and anteriorly truncate, lltli circular in outline, the last three form a 

 loose club ; head rather rugosely and thickly punctate, and with the thorax slightly 

 eeneous, the eyes are very prominent, and the surface between tliem uneven ; thorax, 

 anterior angles are rounded off, and the lateral edges have four denticulations, the 

 basal tooth largest ; elytra punctate, punctures somewhat shallow and rugose, black 

 variegated with luteous patches, the region of the scutellum being usually dark. 

 Tlie head beneath has, in common with other species of the genus, a wide, smooth 

 space bordered by an area of large punctures. There are no fovese in the mentum 

 in the male. 



This species is similar to E. lyncea, Pascoe, a species I found not 

 uncommonly in Ceylon. 



Hah. : Kiushiu. I took eiglit examples in the forests on the 

 banks of the Kumagawa in Hiogo in May, ISSl.
