Genus PKODORETUS. 



Prodoretus, Brenske, Soc. Ent. viii, 1893, p. 1 ; Ohaus, Deutsche 

 Ent. Zeits. 1912, p. 269. 



TYPE, Prodoretus vittatus, Brenske (Madagascar). 



Range. Tropical Africa, India, Madagascar. 



-Body ovate and convex. Eyes large and prominent ; clvpeus 

 small, semicircular or trapezoidal. Antennas 10-jointed, club 

 moderately long. Labrum transverse, without median lobe (see 

 fig. 59 d). Mandibles strong, interlocking, not toothed, molar 

 ridges very coarse. Maxilla and labium very various. Maxilla 

 with 2-4 teeth, blunt or very sharp, palpus generally slender. 

 Labium broad and truncate, or long and attenuated, with palpi 

 widely separated or close together. Front tibia sharply 3-dentate, 

 the two upper teeth separated by a sharp notch. 



A number of species of very varied head- and mouth-structure 

 have been put together under the name of Prodoretus by Ohaus. 

 They agree only in having the labrum not produced in the middle, 

 and it is not easy to see why Phceadoretus was not also added. 

 They appear to be rare insects, and it is perhaps wise to await 

 additional means of studying them before at tempting a satisfactory 

 classification. I do not know the two Indian species included by 

 Ohaus, whose descriptions I have translated as follows : 



301. Prodoretus bombay anus. 



Prodoretus bombayanus, Ohaus, Deutsche Ent. Zeits. 1912, p. 273. 



" Cylindrical, convex, shining testaceous-yellow, rather paler 

 beneath, the anterior part more reddish yellow, the head blackish 

 brown, all the margins and the teeth of the front tibiae dark. 



Head rather large, with large eyes, the clypeus nearly semi- 

 circular, with a finely reflexed margin, reddish brown, with 

 moderately close annular punctures, the walls of which disappear 

 posteriorly, each puncture with a short backwardly directed seta.
