NEW PHYTOPHAGOUS COLEOPTERA 50 



prominent , surface deeply and regularly punctate-striate , the 

 punctures much stronger at the sides than near the suture at 

 whicli latter place they form two or three double rows; elytral 

 •epipleurae very broad, slightly concave; underside and legs more 

 or less piceous or fulvous. 



New Guinea, Fly River (L. M, D'Albertis). Two specimens. 



Aplitlionoides, n. gen. 



Body oblong-ovate ; eyes entire ; palpi filiform ; antennae slen- 

 der, the second joint thickened and longer than the third; tho- 

 rax nearly squareshaped ; scutellum very small ; elytra punctate- 

 striate; posterior femora strongly incrassate^ furnished with a 

 long and acute spine which extends beyond the tibiae; the latter 

 unarmed (?) first tarsal joint very small, the second smaller 

 still; claws simple; presternum squareshaped, broad; anterior 

 coxal cavities incomplete. 



It will be seen that the little insect upon which I am obli- 

 ged to found the present genus is one of the most interesting 

 amongst the immense family of Halticinae. The general shape 

 is that of a small AplUhona, but many differences of structure 

 prevent its ])eing mistaken for one of that genus. The prester- 

 num is broad and squareshaped, the elytra are punctate-striate, 

 the tarsal joints of which it is difficult to detect the se- 

 cond are altogether much shorter than in AplUhona, Ixit most 

 important of all is the curious sting like spine which being fi- 

 xed at the apex of the posterior femora extends distinctly ])e- 

 yond the length of the tibiae; whether this curious structure is 

 only peculiar to the male insect I am not able to say but in the 

 dozend specimens before me it is constant; I am also not quite 

 sure as to the armed or unarmed tibiae at which I was not 

 able to detect a spine at their apices although the smallness of 

 the insect might have prevented me from observing it. 



54. Aplxtlioiioicles Beeearii, n. sp. 



Black; legs more or less piceous; antennae, with the exception 

 of the 4 terminal joints which are piceous, testaceous; thorax
