162 Longicornia Malayana. 



anteriorly, finely and remotely punctured ; scutellura moderate, 

 transverse ; elytra with rather small but very distinct punctures, 

 and two large whitish patches on each, occupying nearly the 

 same position as in the first species, but not so marked as they 

 approach the suture, the rest of the elytra more or less shaded 

 with brown, the apex of each shortly but very decidedly divari- 

 cate, the outer angle obliquely truncate ; body beneath and legs 

 covered with a very fine, close, fawn-coloured pile ; antennae 

 dark brown, the third, fourth, and fifth joints greyish pubescent 

 at the base, the first coarsely punctured. 

 Length 10 lines. 



Xylorhiza. 

 Xylorh'izay Laporte de Castelnau, Hist. Nat. des Insectes, ii. 476. 

 Capnt antice transversum, tuberibus antenniferis validis, basi 

 approximatis. Oculi angustati, late emarginati. Antennce 

 corpore breviores, baud fimbriatae ; scapo basin versus tenui- 

 ori ; articulo tertio longiori ; ceeteris gradatim brevioribus. 

 Prothorax capite non latior, inaequalis, antice constrictus, 

 lateraliter spinosus vel inermis. Elijtra elongata, prothorace 

 multo latiora, ad latera paulo incurvata, apicibus producto- 

 laminatis. Pedes breves ; femora fusiformia ; tibiae tarsis 

 baud longiores, intermediae fortiter emarginatae. Pro- et 

 meso-sterna depressa. 

 A grand and well-known species is the type of this genus, but 

 I have so far generalized its characters as to include Xylorhiza 

 spumans (Guer. ?) and a few others yet undescribed. Unless we 

 limit Xylorhiza to X. venosa, I do not see how Cymatura, Gerst., 

 is to be distinguished from it, and if we adopt Cymatura (on ac- 

 count chiefly of its spined prothorax), we should have either to 

 refer to it a number of very incongruous species, or to provide 

 for them new genera, which would be hardly more desirable. 

 Latreille gives a very poor figure of the type in the " Regne 

 Animal," iii. pi. xviii. fig. 7, under the name of '* Lamie veirice," 

 but it is not mentioned in the text.

Everywhere covered with a beautiful dense silky pubescence, 

 mostly black, but with clear fulvous lines, especially on the elytra,
