1108 rOLKOPTERA 



Head distinctly punctured. Prothora.r broader than long, 

 curvedly narrowed anteriorly, the sides elsewhere but little rounded, 

 base subtruncate ; disc convex, moderately coarsely punctate, \vith 

 a deep longitudinal groove along each side, iiot parallel to the 

 margin, but nearer the side in front than behind. Scutelhim^vaooih. 

 Elytra but little wider than thorax, widest behind the middle, 

 not much rounded laterally and a little produced behind ; they are 

 striate, the strige are not perceptibly punctured, they are deeply 

 impressed near the base, nearly obsolete on the middle, and the 

 interstices are so punctuated as to cause a somewhat rugulose ap- 

 pearance. The tibice and tarsi bear fine yellowish hairs. 



Underside punctulate, pitchy-brown, clothed with short yellowish 

 hairs. 



Length, 2^ lines ; breadth, f line. 



Tairua. One, found under a log. 



The above descriptions are substituted for Parnida agrestis (No. 

 440), that generic name having been objected to. The antennal 

 description has been altered from the original, as was found neces- 

 sary. 



Group-LUCANID^. 



Lissotes. 



1966. Li. ithaginis, "•■^■- Opaque, fusco-niger, clothed with 

 juinute yellowish setas ; ovate-oblong, but little convex. 



Head much narrower than thorax, widest behind the eyes, 

 nearly plane, its punctation distinct but irregular. Eijes small, 

 distant from thorax. Mandibles short and thick, coarsely punctate, 

 bearing an obtuse tooth inside near the extremity, and a more pro- 

 minent one above near the middle, directed obliquely upwards. 

 AntenncB 9-articulate, the three terminal joints densely pubes- 

 cent, the ninth with a punctiform cavity. Thorax strongly trans- 

 verse, obtusely angulated laterally just behind the middle, more 

 narrowed behind than in front, apex finely marginated and widely 

 bisinuated, side margins thick, base subtruncate, posterior angles 

 blunt but not rounded off as in L. helmsi ; its punctation rather 

 close but not very coarse except near the sides. Scutcllum short 

 and broad, curvilinearly triangular, with few punctures. Elytra 

 widest at base, much narrowed apically, without distinct costae, 

 their sculpture similar to but rather finer and denser than that of 

 the thorax. x-Vnterior tibice sulcate and punctate above, armed with 

 a large prominent tooth near the extremity, besides two or three 

 smaller ones ; the other two pairs grooved and punctated, with an 

 acute tooth beyond the middle, and clothed with fulvous setse. 



Underside somewhat glossy, finely and distantly punctu)-ed, sides 

 of head and prosternum nearly smooth, labium distinctly and 

 closely punctate. 



Smaller and flatter than the female of L. helmsi, from which it 

 may be distinguished by the upstanding median tooth on each man- 

 dible, and the position of the eyes, Sec. In the female of L. helmsi 

 the head and thorax are more or less reuularlv curvate.
