Tanychilus. 



Newman; Lacord. Hist. des. Ins. Coleop., Tom. v.,/, 498. 



Terminal joint of the labial palpi triangular ; that of the maxillary 

 palpi sub-cultriform. Labrum prominent, a little sinuated, with rounded 

 angles. Mandibles prominent, rather straight, but arcuated at the 

 extremity. 



Head very prominent, narrowed behind the eyes, with an elongated 

 muzzle : epistome subquadrate, longer than broad ; eyes prominent, reni- 

 form, sub-contiguous above in the males, less so in the other sex. An- 

 tenna long and slender ; the basal joint moderate, ovate, second trans- 

 versal, joints three to ten decrease in length, narrowed at their base, 

 eleventh attenuated at apex. Prothorax moderately convex, subconical, 

 truncated at apex. Scutellum triangular. Elytra a little wider than 

 thorax at their base, moderately convex, moderately elongated ; epipleu- 

 rae entire. Legs long ; thighs robust ; tibia straight, their spurs slender, 

 those of the posterior longest ; tarsi elongate, the basal joint of the hind 

 pair large ; the two penultimate joints of the four anterior pairs, and the 

 penultimate only of the posterior, lamellated. Intercoxal process promi- 

 nent, subtriangular. Body long and arched above. 



698. T. metallicus, White; Voy. Er. Terr., Ins., p. 12. Above 

 of a deep metallic shining green, darkest on the head and thorax; 

 under-side of body and legs deep blackish-brown \ head with the eyes 

 distant, above finely punctured, a small, smooth space in the middle ; 

 thorax very smooth, with two or three impressions behind ; elytra with 

 eight longitudinal, closely punctured striae, and one much abbreviated 

 close to the scutellum ; the five inner rather deeply grooved, the three 

 outer quite .superficial. 



Wellington (Capt. Parry). 



NOTE. I have a specimen from Wellington, sent to me by Mr. 

 J. Buchanan, F.L.S., which agrees with White's description, and 

 measures 4^ lines in length. 



Var. rufescens. 



The present specimen seems to differ from T. metallicus in its rather 

 more elongate form ; the body is infuscate red with a greenish hue, 

 the legs, in most specimens, are clear testaceous, the penultimate 

 joint of the tarsi is fuscous, the others, as well as all but the three 

 basal joints of the antennae, are obscure rufo-testaceous. The head 

 is rather coarsely punctured, with scarcely any smooth space. The 

 prothorax is subconical, rather narrow, and finely punctured, except 

 at the base, where there is a transverse central depression, and one at 

 each side, which are more closely and coarsely punctured than the disc. 

 The elytra are moderately elongated, and less incurved laterally near the 

 middle than in T. metallicus ; (in that species their widest part is in line 

 with the posterior femora, and they are from thence rather abruptly 

 rounded to the apex ; in this species they taper more gradually) ; each 

 elytron bears eight punctured striae and a short scutellar striole. 



Length, 4^ lines.
