Enctclops olivaoeus, n. sp. (Plate I. fig. 7.) 



Elongatus, linearis, olivaceo-seneus, subtiliter (oapite thorace- 

 que densius) griseo-j)ubescens, antennis pedibusqne testaceo- 

 rufis nigro-maculatis. Capite et thorace creberrime alveolatis, illo 

 postiee tumido-quadi^ato, oculis intus baud profunde sinuatis ; 

 boc medio utrinque tuberculo conico, antice et postiee parum 

 coijstricto ; disco modice convexo ; elytris passim discrete punc-

Cbiuzenji and Omine. 



Differs from tlie Nortb- American genus JfUncyclops ouly in the 

 shallower emargination of tbe eyes. In this respect it agrees 

 better with Microrhabdium^ Kraatz, of E. Siberia; but Kraatz 

 does not mention the finely faceted eyes, by his silence leaving 

 it to be inferred that in his geaus they are coarsely faceted, as 

 is ^ylosteus, Psilorhahdium, and Leptorhabdium, with which alone 

 he compares it. The terminal joint of the palpi is short and 

 strongly securiform, the antennae are inserted nearly opposite the 

 middle of the eyes ; the tarsi are all slender, the first joint very 

 elongated, in the hinder feet longer than the remaining joints 

 taken together. The close, shallow, alyeolate punctuation of the 

 head and thorax speaks, in addition to other structural simila- 

 rities, for the generic union of the species with Encyclops. The 

 antennae are red in their four basal joints, with the tips black 

 (the scape having a long black streak), and black in the other 

 joints with the base of each red. The legs are red, with a long 

 spot on the femora, a smaller one on the tibise, and the tips of the 

 tarsi black.
