1198 COLEOPTEEA 



rugosus, elytris apicem versus latioribus, disco pone medium quad- 

 rangulariter prominulo, quasi truncato. 



Long., 8mra. ; rost. incl., 11mm. 



Upper surface of rostrum with four grooves, the lateral being less 

 distinct than the two median ; second and third joints of antennce 

 moderately long, subequal : thorax subcylindric, nearly as long as 

 broad, slightly narrowed towards the front on the anterior third, 

 longitudinally depressed along the middle, and, with the surface 

 coarsely rugose : elytra with slight elevations not sufficiently marked 

 to be termed nodules, and also with regular series of impressed 

 rather distant punctures ; apparently truncate behind, the disc form- 

 ing two slight angles near the suture, and also an external angle on 

 each side, the apical declivous part large ; the width of the wing- 

 cases at the base is the same as the base of the thorax, and there 

 is a very minute scutcllum : the legs are thick, the front tibiae mucro- 

 nate, the claws short and thick ; in addition to the squamosity of 

 the surface there are also a few pallid sette, which become numerous 

 on the legs. 



Picton. Helms ; a good series. 



2121. H. horridus, n.s. (Sharp; Trans. Boy. Dub. Soc, 

 1886, p. -±27.) Niger, tuberculato-rugosus, indumento sordid© plus 

 minusve obscuratus, elytris apicem versus latioribus, disco pone 

 medium quadrangulariter prominulo, quasi truncato. 



Long., 7mm. 



This differs from H. insolitus by the very rough surface ; it is 

 also of less elongate form, with a shorter rostrum, which also has 

 less definite scrobes ; the thorax is broader than long, slightly nar- 

 rowed behind, more narrowed in front, its surface coarsely and 

 deeply rugose ; elytra without punctuation, but with a large number 

 of small tubercles irregularly placed, they become broader behind, 

 and are abruptly declivous at the extremity, the dorsal portion pro- 

 jecting backwards as four short obtuse angles, the lateral prominence 

 on each side not reaching so far back as those near the suture ; legs 

 rather short. As in H. insolitus, the corbels are not in the least 

 cavernous. 



Otago, Bakewell ; Duuedin, Professor Hutton : one [example 

 from each. 



Haplolobus. 



Nov. gen. 



Bostrumvevy short and thick, forming a prolongation of the head 

 without any ante-ocular contraction, a little narrowed anteriorly, 

 not pterygiate, more or less obviously triangularly grooved in front. 

 Scrobes situated on upper surface rather than on the sides, so that 

 if their upper margins were continued backwards they would almost 

 converge on the vertex ; they are apical, nearly foveiform, and deep. 

 Eyes small, scarcely convex, obliquely oval and somewhat pointed 

 below, widely separated above, placed quite laterally and only a 

 short distance from the thorax. Scape thickened apically, attaining
