580 Longicornia Malayana. 



Hah. — Sarawak. 



Deep black, closely punctured; head with a narrow 

 groove between the eyes; fifth joint of the antennee 

 obconic, the first triangular joint being the sixth ; pro- 

 thorax as in the preceding species; elytra flattish above, 

 the line of deflection rounded, two silvery white bands 

 dividing them into three equal parts, apices strongly 

 bispinous ; body beneath, with the posterior edges of the 

 metasternum, and of all the abdominal segments, bordered 

 with white hairs. 



Length 8-10 lines. 



Mr. Wallace observes of this species, that it flies slowly 

 and settles on newly fallen timber. M. Lacordaire erro- 

 neously refers it as a second species to my genus Asmedla. 

 The latter belongs to the CaUtchromrnce, and has only 

 occurred to my knowledge at Penang.

Caput antice paulo productum, inter antennas parum 

 excavatum. Oculi prominentes, late emarginati. 

 Antennae {$) corpore paullo longiores, ( c? ) breviores ; 

 scapo subcylindrico, arcuato ; articulo tertio duplo 

 quarto longiore, 6-10 apice lateraliter dilatatis, ultimo 

 appendiculato. Prothorax latitudine vix longior, 

 antice angustior, lateraliter rotuudatus. Elytra bre- 

 viuscula, subdepressa, epipleurge angustatae. Pedes 

 antici et intermedii mediocres, postici elongati; 

 femora parum incrassata ; tihicB graciles ; tarsi postici 

 elongati, articulo basali cjeteris simul sumptis lon- 

 giore. Prosternum angustatum, elevatum. Meso-

The species described below I first referred doubtfully 

 to Blenmiya, and subsequently proposed to constitute it 

 a distinct genus. M. Lacordaire, however, considers it 

 to be only a degraded foi*m of Prothema. The two spe- 

 cimens before me, are, I believe, from the comparative 

 shortness and dilatation of their antennae, females; on 

 the other hand, the two original species of Protlienia in
