CRYPTORHTNCHIDAE. 573 



Rostrum slightly longer than thorax, moderately arched, a little broader 

 at the bare apex than at the base, with obscure squamae and a few erect 

 fuscous setae. Thorax conical, subtruncate at base, quite a third broader 

 than long ; the disc nearly plane, moderately closely and coarsely punctured, 

 the lateral cilia not covering the true sides in front. Scutellum absent. 

 Elytra cordate, nearly thrice the length of thorax, distinctly broader than 

 it is at the base but with oblique shoulders ; apparently striate-punctate, 

 with a few small black granules near the base ; from each shoulder towards 

 the commencement of the posterior declivity the squamae form a slightly 

 raised curve, this, behind, has a blackish border, there is a more irregular 

 curvature in front, another dark fuscous streak near each hind thigh 

 extends half-way towards the suture. 



Scape medially inserted ; basal two joints of funiculus equally elongate, 

 joints 3-7 moniliform, club oblong-oval. Legs elongate, with coarse, 

 fuscous, outstanding setae ; femora only moderately dentate. 



This species, with the exception of the medially implanted scape, almost 

 accords with Crisius. The thoracic disc, owing to the short lateral cilia, 

 appears triangular; there is no frontal constriction. The head is impressed 

 between the eyes. 



Length (rostrum exclusive), 5 mm. ; breadth, 3 mm.

 4121. Tychanus obscurus sp. no v. 



Oblong-oval, moderately convex, subopaque ; fusco-piceous, rostrum and 

 front of thorax rufescent, tarsi and antennae chestnut-red ; thinly clothed 

 with depressed squamae, those on thorax and base of elytra pale testaceous, 

 remainder of elytra with small, flat, inconspicuous, dark ashy ones, the 

 sides of thorax, and the hind-body, with a few suberect pale scales. 



Rostrum arched, gently narrowed towards the middle, slightly shorter 

 than thorax, finely punctate and shining in front of the antennae, more 

 closely and coarsely behind, obsoletely carinate along the middle. Thorax 

 a sixth broader than long, its frontal half somewhat depressed and abruptly 

 contracted, the basal portion rather more closely and coarsely punctured 

 and with a slight carina along the centre. Scutellum very short. Elytra 

 oblong, gradually narrowed and deflexed behind, double the length of 

 thorax, very little broader than it is at the base ; distinctly subseriate- 

 punctate, with a few minute granules near the base, interstices nearly plane, 

 their apical portion with many dark, outstanding but rather short 

 squamiform setae. 



Scape inserted just before the middle ; basal joint of funiculus thicker 

 and a third shorter than the elongate second, third and fourth slightly 

 longer than following two, seventh rather broader, quite transverse ; club 

 elongate-oval. 



Legs elongate, with pale coarse setae ; femora strongly- dentate under- 

 neath ; tarsi narrow. 



This obscurely clothed species may be placed near T. lunalis (3934), in 

 which, however, the club is shorter and the third joint of the fimiculus 

 unusually short. 



Length (rostrum exclusive), 4| mm. ; breadth, 2^ mm.
