the ElnteridfP of Japayi. 31 



gested black scales, immediately before the scutellum on the 

 basal edi^e is a small nodule ; the elytra punctate-.striate, 

 variegated with ashy and brown scales ; near the middle on 

 the lateral edge is a large dusky spot, semicircular on the 

 inner side and on the sixth and seventh interstices densely 

 black, apices widely emarginate and obtusely pointed at the 

 fourth interstice. 



This species approximately resembles A. putridus^ Cand., 

 but it is much more robust, frontal protuberances not pointed, 

 thorax less parallel, and the apices of the elytra widen out 

 more and correspond more to those figured for A. lateralis^ 

 Cand. (Cand. Mon. 1857, pi. iv. fig. 16). There is an 

 undescribed species in the British Museum from N. China 

 which resembles it more closely than A. j)utridus. 



llab. Nagasaki, Kumamoto, Konose, and Hagi [Hiller). 

 I found this species not uncommonly in Higo under bark of 

 lirs (Kuromatzu). Alaus berus, Cand., occurs in the same 

 fir and is common everywhere, especially at Bukenji, near 

 Yokohama, in early summer.

 Tetrigus grandis, Lew. Eut. Month. Mag. 1873, p. 155. 



Cand^ze's type is an example from Kobe measuring 

 25 mill. only. Ordinary examples measure 30-31 mill., and 

 one of these I mistook for a new species. 



Hab. Nagasaki, Kobe, and Sapporo. 



Pectocera Fortuneij Cand.

This species is of crepuscular habit. I saw the males in 

 June flying in circles at Nikko near oak trees, far out of 

 reach ; but the females are very sluggish. The pectination 

 of the antennse in insects of this description assists in balauciuo- 

 the body during flight, the females with slender articulations 

 being unable to float in mid-air. 



Eab. Nagasaki, Kumamoto, Nikko, and Chiuzenji. 

 Common. 



Anckastus musy sp. n. 



Aterrimus, subopacus, griseo-pubesceiis ; capite parvo, parum dense 

 punctate; elytris striis tenuiter impressis, interstitiis rugoso- 

 punctulatis ; antcnnis pedibusquc uigris.
