Longicornia Malayana. 55 



abrasion), the transverse lines well marked ; scutellum triangular ; 

 elytra clothed with a coarse ashy-mottled pubescence, which is 

 divided into two portions behind the middle by a somewhat 

 V-shaped band, this is sometimes extended along the suture to 

 the apex, and the ashy part within becomes lighter and more 

 strongly marked, or all these marks become very indistinct, and the 

 elytra are nearly uniformly brownish ; body beneath pitchy ; legs 

 reddish-pitchy, with numerous long scattered hairs ; anteimae 

 entirely dark brown, or dark brown with the basal half of all the 

 joints except the first and second ashy. 



Length 2| lines. 



A specimen from Mysol is the most uniformly coloured of this 

 species, and those from Aru have annulated or plain antennae, as 

 the case may be_, indifferently, 



Oloessa. 



Caput antice quadratum, fronte convexa, tuberibus antenniferis 

 nullis. Oculi divisi. Antennce remotae, subelongatae, Iseves, 

 sed apicem versus ciliatae ; scapo longissimo, basi attenuate, 

 apice tuberoso, articulo tertio secundo parum longiore, caeteris 

 longioribus, aequalibus. Prothorax longior quam latior, antice 

 latitudine capitis, postice coarctatus, lateribus inermis. Elytra 

 brevia, basi depressa, et spina armata. Femora basi tenuis- 

 sima, dein abrupte dilatata; tib'ice validae ; tarsi breves, ar- 

 ticulo ultimo elongato. Coxce anticse et intermediae distantes. 

 Corpus breviter setosum. 



In the form and length of the scape this genus is almost ex- 

 ceptional in its sub-family, and it is quite so in its divided eyes. 

 It has, however, the arched thorax of Ebceides and the elytra of 

 Gyaritus ; and what is more remarkable, it is so closely allied to 

 the North American genus Cyrtinus, Lee* (^Clytus pygmceus, 

 Hald.), that except in the antennae and eyes I scarcely see how 

 it differs. In both the femora are extremely attenuated at the 

 base, then suddenly dilated, especially on the upper edge. The 

 species upon which the genus is founded is one of the smallest of 

 the Lamiidae, scarcely exceeding a line in length. 



• Dr. Leconte places this genus with the Dorcadions ! Three very anomalous 

 genera, Microplia, Serv. {LeptopUa, Dej.), Omosarotes, Pasc.and Scopadus, Pasc. 

 (all South American) should also, I think, be placed near the above. The first 

 of tiiese has the long scape, attenuated at the base, and gradually enlarging up- 

 wards, of Oloessa; the last two have the " Cyrtinine " profile in perfection, while 

 in Microplia it is only just beginning lo develope itself, as in the case of Gyarilus, 

 but after another type.
