1258 COLEOPTEBA 



forming striae ; the base and apex, and an irregular spot near each 

 hind thigh, on the fourth, fifth, and sixth interstices, darker than the 

 rest of the surface. 



Length, 1J lines ; breadth, line. 



Waitakerei. One example. 



OBS. 1. No. 976 belongs to this genus, and is the species from 

 which the generic characters were taken. It becomes, therefore, 

 Eugonissus conulus. It is distinguishable from the preceding species 

 by its larger size and maculate antennae. 



OBS. 2. No. 977 must also be placed in Eugonissus. It may be 

 easily recognised by the almost silvery- white scale-like hairs along 

 the elytral disc, bordered externally behind the middle by broad 

 fuscous spaces. The antennae are rather longer than in the typical 

 species, and the second joint is nearly of the same length as the 

 first ; the outer angle formed by the carina is not quite so prominent ; 

 and the elytra are rather longer ; but, notwithstanding these dis- 

 crepancies, it does not differ in essential characters. 



Dysnocryptus. 



Nov. gen. 



Eyes transverse, coarsely facetted, convex, entire. Rostrum 

 very short, truncate in front. Antenna implanted close to the 

 inner and front part of the eyes, much shorter than the body, bear- 

 ing some erect hairs or fine setae ; basal joint widened towards the 

 extremity, straight externally, much rounded on the inside ; second 

 joint rather shorter than the first ; joints 3-8 slender, decreasing in 

 length ; the three last form the club ; tenth joint broader than long. 

 Thorax large in proportion to the hind-body ; its carina moderately 

 distant from the base, rounded but not sinuate, sometimes medially 

 angulate, obsolete along the sides. Scutellum invisible. Elytra 

 short, almost rotundate, evenly convex. Legs rather long and 

 stout, the anterior longest ; tarsi rather short and broad, basal 

 joint not twice the length of the second, which is hardly any longer 

 than the bilobed third joint, claws toothed. Metasternum and 

 abdomen short. 



This genus comes near Notioxenus (Lacordaire, Hist, des Insectes 

 Coleopt., torn, vii., p. 594), but the figure given (No. 6, Plate 80) 

 represents a form quite different from the species which I propose 

 placing in Dysnocryptus ; the structure of the tarsi and antennae too 

 is quite different, but perhaps the figure does not accurately agree 

 with Wollaston's type (Notioxenus rufopictus). 



2216. D. plagiatUS, n.s. Shining, testaceous, the thorax 

 with a broad central, and an oblique lateral, streak, confluent in 

 front of the middle, blackish ; a large space on the elytra, occupying 

 more than half of the surface, also piceous ; legs infuscate, the knees 

 and extremity of tibiae still darker; antennae testaceous, club infus- 

 cate ; nearly glabrous, having only very few hairs,
