COLEOPTERA 489 



seriatim puiictatis ; abdomine vix crebre sed conspicue 23unctato. Long. corp. 2- 



3 mm. ; lat. corp. circa i^ mm. 



This species is distinguished from N. koelensis, cognatiis, &c., by its slightly larger 

 size and greater relative breadth. There is considerable variation in colour, also in the 

 degree of closeness of the punctures ; the latter being decidedly scanty on the prothora.x 

 in some females, as is the case in certain allied forms. 



In the male, the emargination of the pygidium is conspicuous, outline of the notch 

 rounded, the tooth on either side somewhat sharp ; supplementary segment emarginate; 

 but ventral segment more conspicuously emarginate than in allied forms, the emargina- 

 tion being deeper and not so broad, and having a somewhat rounded outline. Female 

 pygidium variable ; sometimes rounded apically and with a distinct central emargination, 

 sometimes more nearly truncate and scarcely emarginate at all.

This species is very closely allied to N. latitcscu/us, cognatus, and koelensis. From 

 the two latter it is distinguished by its larger size and greater width ; in this respect it 

 comes nearer to the former, from which, however, it is distinguished by the form of the 

 prothorax and the slightly smaller breadth. Moreover it is separated from all three 

 species by the form of the male pygidium, which is apically rather broad, the notch 

 being shallow and the tooth on either side of it but little produced. Male supplemen- 

 tary segment emarginate ; last ventral with the emargination broad and shallow as in 

 N. koelensis, not deeper and rounded as in N. latiusculiis. Female pygidium sinuate at 

 the sides, slightly rounded and more or less depressed apically; last ventral segment 

 scarcely bisinuate, almost truncate. 



As in the allied species, the punctures on the prothorax are less numerous in the 

 female than in the male. 



The colour is extremely variable. Testaceous or yellowish patches are usually 

 present on the elytra, but their extent and outline differ greatly in various specimens. 

 In some the light colour is so extended on the posterior part of the elytra as to give rise 

 to conspicuous specimens of the var. dimidiatus, which is so frequent in the genus 

 Eupetinus.
