new Species of Hister'idsd. 21 



Ilab. Clarence River, New South Wales (Lea, 1235). I 

 am indebted to Mr. A. M. Lea for specimens of this species, 

 which have been carefully compared with Macleay's type. 



Paromalus niponensis, sp. n. 



In the Ann. & Mag. Nat. Hist. (6) ix. p. 33 (1892) T 

 recorded this species from Japan as P. complanatus^ Panz., but 

 having more recently set up a large series, I find that all the 

 Japanese specimens are different in small but important parti- 

 culars. The general outline of the body is less oblong — that 

 is, it is relatively broader than P. complanatus, the breadth 

 being particularly seen in the width of the thorax and meso- 

 sternum ; the legs and antennse are less elongate; the head more 

 distinctly punctured, with the lateral border more elevated; 

 the thorax has the marginal stria minutely interrupted in 

 the middle behind the neck, and the anterior angles are more 

 acute ; the sculpture of the pygidium in the male is variable, 

 but it is usually deeper, and the anastomosed sculpture is 

 bordered behind usually with a semicircular furrow ; the 

 niesosternum has an indistinct biarcuate transverse stria, and 

 its lateral stria terminates at the base rectangularly. Marseul 

 says the head of P. complanatus is smooth, but there are fine 

 and feeble points on the surface ; the mesosternum has the 

 lateral strige hamate at the base, and its transverse stria is 

 fine but very clear and consists of a single arc. 



Long. 3-3j mill. 



Bab. Found throughout Japan, chiefly under the bark of 

 beech. 



Paromalus mendicuSj Lew. 



This species was originally found in S. Japan, but in 1890 

 Herr J. Schmidt informed me that he had received it from 

 Java. 



Tribalus Lece^ sp. n. 



Ovalis, convexus, niger, nitidus ; fronts modice prominula, utrinque 

 breviter striata ; pronoto sparse punctulato, punctis grossis inter- 

 mixtis ; elytria striis suturalibus antice abbreviatis ; prosteruo 

 bistriato ; mesosteruo postice crenulato-striato, stria recta. 



L. 2i-2| mill. 



This species, like several from Eastern Asia, has a sutnral 

 stria which diverges from the suture anteriorly. It is ex- 

 tremely like T. Tca^nigiuSj Mars., but it is more oval, less 

 convex in the dorsal region, the punctuation of the thorax and
