Longicornia Malayana. 163 



where they inosculate towards the apex, the fulvous predomi- 

 nating on the head, the black on the prothorax ; on the latter are 

 two fine central lines continued from the vertex, and on each 

 side a still finer line, often bifid posteriorly ; the elytra at the 

 base are generally entirely black, then follow stripes of black 

 and fulvous, the proportions varying considerably ; body beneath 

 and legs dark chesnut-brown, more or less marked with yellow 

 stripes ; antennae very pubescent, mostly fulvous. 

 Length 15 — 22 lines. 



Praonetha. 

 Prioneta (ab errore) Blanchard, Voy. au Pole Sud, iv. 292. 

 Caput antice siibquadratum, tuberibus antenniferis validis, basi 

 approximatis vel subapproximatis. Oculi raediocres, pro- 

 funde divisi. Antennce corpore breviores, rarissime in ma- 

 ribus longiores, setaceae, subfirabriata^ ; scapo cylindrico 

 vel subcylindrico ; articulo tertio longitudine scapo aequali, 

 rarius longiori vel breviori, subcurvato, apicem versus gra- 

 datim incrassato;* quarto siraillimo vel subaequali ; sequen- 

 tibus sensim brevioribus ; articulorum apicibus aliquando 

 productis, vel spinosis. Prothorax capite latior, plus minusve 

 subquadratus, ad latera subrotundatus, vel subparallelus. 

 Elytra subbrevia, convexa, saepissime compressa, generaliter 

 supra inaequalia. Pedes mediocres ; protibice fere rectae, 

 rarius paulo curvatae, intermediae baud emarginatae ; tarsi 

 aequales. Pro- et meso-sterna modice elevata. 

 The diversity of form to a certain extent of many of the species 

 here brought together may, no doubt, be objected to, but, after a 

 careful examination, I cannot see that anything like a satisfactory 

 limitation can be established even in dividing them into sections, 

 although I have attempted to do so, but solely with a view to 

 facilitate their descriptions. The whole, when fairly compared, 

 and not putting extremes into juxtaposition, will, I think, be 

 found to compose, considering its great extent, a tolerably ho- 

 mogeneous group, which a practised eye will at once distinguish. 



* The following, described by me as a Praonetha, must be separated from it 

 to form a new genus. 



Desisa. 

 Characteres ut in Praonetha, sed oculi modice emarginati : antennce corpore 

 longiores, tuberibus antenniferis basi distantibus, articulis cylindricis, 

 rectis, apicibus baud productis vel incrassatis. 

 The type is Praonetha subfasclata (Journ. of Entom. i. 348). It is from 

 Cambodia.
