TWO NEW XEXOCERVS (AyTHRIBIDAE) IN THE 



COLLECTION OE R. VON BENNIGSEN. 



By KARL JORDAN. 



1. Xenocerus bennigseni spec. nov. 



? . Black ; pubescence creamy white. Antennae reaching beyond middle of 

 ^lytruui, pL'caliar in strnctnre ; segment 7, base of 8 and apex of 6 grey, 1 to G 

 clothed with brushes of brown hairs ; segments 1 and 3 short, 2 almost thrice as 

 long as 1, equalling 4, this a little shorter than ;j = 6. I'rothorax broadly and 

 deejily impressed longitudinally in middle, the imjiressiou occupying nearly one-third 

 the width of the prouotum, narrowing apically, tilled in with creamy-white 

 pubescence ; a slightly darker vitta on the side, partly obliterated. Elytra broadly 

 impressed at the suture, the impression rather sharply limited laterally ; apical 

 declivity irregular, each elytrum being elevate in middle at the beginning of the 

 declivity and impressed laterally of this elevation ; base also more strongly 

 impressed at shoulder than usually ; pubescence creamy white ; a large lateral 

 area brown, reaching from basal fourth to apical declivity, irregular, extending 

 upwards in middle to the elevate third interspace, and posteriorly produced into 

 a narrow, irregular, transverse band which runs over the suliaiiical elevation and 

 is dilated forward upon suture; two large round dots on elevate third interspace 

 {but extending to second and fourth interspaces) black, one subbasal, the other 

 autemedian, joined to the fuscous lateral area ; humeral and apical areas somewhat 

 marmorated with fuscous. 



Pygidinm creamy white. Underside the same laterally, less densely pubescent 

 in middle ; abdomen with a row of small black lateral spots. Process of mcso- 

 .sternum sub-bitubercnlate. Femora and tibiae rufescent. 



Length : 17 mm. 



llab. Sattelberg, Hnon Gulf, German New Guinea (R. v. Bennigsen). 



One 3. 



The remarkable structure of the antennae and the broad impression of the 

 pronotum and elytra distinguish this species from all the others which are known. 



2. Xenocerus lacrymans herbertus snbsjjec. nov. 



(J ? . Differs from A'. /. lacnjimns iu the pattern of the elytrum : the basal 

 sntural stripe is thinner, the rounded cordiform sutural spot is replaced by an 

 anguliform spot,. the anterior lateral spot is transverse, irregular, the postmedian 

 lateral spot is more transverse than in /. lacnjmans, being often continuous with the 

 sntural anguliform spot, and the apical si>ot is smaller. 



Ilab. HerbertshOhe and Baining Jits., Gazelle Peuiusnla, Neupommern 

 (R. v. Bennigsen). 



Two jiairs. 



This form is interesting inasmuch as it forms a transition from the i)attern of 

 X lacri/nnvts /acn/ma/is to the ordinary Xenocerus pattern.
