Hah. Madagascar. 



This is a very distinct species, and may be hereafter con- 

 sidered to be generically distinct from P. sex-notata. 



Praonetha Dohrnii.

 pubescens ; antennis subannulatis, articulo tertio quam jtrimo vix 

 longiore ; prothorace subtrausverso, vage punctato, in medio bi- 

 calloso ; scutello transverso ; elytris sat brevibus, utrinque gra- 

 datim augustatis, apicibus rotundatis, vage pimctatis, versus 

 apicem subsulcatis, basi et i)onc medium (fere obsolete) nigro- 

 ciistatis, ilia fusciolata ; abdomine leviter maculato. Long.

Hah. Ceylon. 



This little species belongs to my fourth section of the 

 genus (Longic. Malayana, p. 174), characterized by the basal 

 crests and by the gradually declivous posterior portion of the 

 elytra ; but it differs from every other species of the section 

 in the presence of two well-marked tubercles on the prothorax. 

 In so large a genus, where the coloration is confined to various 

 shades of brown with obscure or indefinite spots or markings 

 of greyish or whitish (and even in individuals of the same 

 species there is sometimes a considerable modification caused 

 by the predominance of one or the other of these colours), it 

 becomes very difficult to give an accurate idea of the characters 

 in these respects : in the specimen before me there are two 

 or three concentric black and white lines on the posterior half 

 of the elytra, the innermost black line at its commencement 

 anteriorly marking the position of the postmedian crest (or 

 tubercle). I owe my examples to the well-known polyglot 

 president of the Entomological Society of Stettin, after whom 

 I have named it *. 



Ch^etostigme. 



(Xiphoninte.) 



Caput in medio longitudinaliter sulcatum ; frons convexa. Oculi 

 profunde emarginati. Antennce setacea;, corpora longiorcs, pilis 

 volitantibus adspersae, articulo basali longiusculo, tertio quartoque 

 longioribus, aequalibus, hoc arcuato, caeteris dimidio brevioribus. 

 Prothorax latitudini longitudine aeqiialis, lateribus inermis, basi 



* Dr. Gerstacker ('Die Gliederthier-Fauna des Sansibar-Gebietes,' 

 p. 2G1) enumerates P. melanura, a Malayan species, among the insecte 

 of Zanzibar. His Phori/ctf/.$ mucoreus is evidently Enaretta Castelnaadi, 

 Thoni:*. : and hi.« Phopnh'zn« satisabaricus is a CaUichroina.
