SOME NEW CEBAMBYCIDAE COLLECTED BY ALBERT 

 MOCQUERYS ON THE ISLAND OF ST. THOME, GULE 

 OE GUINEA, WEST AFRICA. 



By Dr. KARL JORDAN. 



Subfamily CERAMBYCINAE. 

 Diaspila gen. nov. 



i ? . Differs from the allied African genera Ili/pomares and Parocme in the 

 fonrth segment of the antenna being only one-fonrth the length of the third, from 

 the American Ibidion especially in the tibiae not being distinctly carinate. 



End-?egmeuts of palpi rather broad. Eyes coarsely granulose, distant above. 

 Antenna of S one-third or half longer, of ? little longer, than the body, with long 

 dispersed hairs underneath and at the apices of the segments, the hairs rather 

 denser on the proximal segments ; scape roughly punctured, little longer than the 

 distance between the upper lobes of the eyes ; third segment one-third or one-half 

 longer than the scape : fourth very short ; fifth and sixth little shorter than third. 

 Pronotnm longer than broad, sides rounded in middle. Elytra parallel, rather 

 flat above, truncate at base, shoulders somewhat rounded. Fore- and midcoxae 

 separate. Femora clubbed, especially in c?, hind ones reaching to end of elytra 

 in c?, a little shorter in ?. Cavity of anterior coxa open behind. 



Type : Diaspila bipuiictatus. 



This species stands as Ci/rtomerns bijiunctatas in the Munich Catalogue ix. 

 p. 2830. We have both sexes from Sierra Leone. 



1. Diaspila periscelis spec. nov. 



Differs from bipunctutux in the following points : antennal segments 2 to tJ 

 black at extreme base ; pronotum much less roughly punctured, more deeply 

 impressed in middle, the convexities on disc therefore more prominent, mesial line 

 somewhat raised behind ; elytra more densely granulate-punctate at base, black spot 

 larger, apex truncate-sinuate, with the outer angle acuminate. Knees black. 



Length, 13 ram. 



One ?. 



2. Xystrocera interrupta spec. nov. 



$. Allied to senegalensis, but differing in structure and in the pattern of the 

 elytra. Prothorax broader than long, widest before basal constriction, sides almost 

 straight in middle, here not rounded, but rather concave in dorsal aspect ; discal 

 mark very narrow, horseshoe-shaped, the space encircled by it wider than in 

 seni'ffaleiisis and marginalis. Elytra slightly dilated beyond middle, and then 

 slightly sinuate ; with three glabrous carinae, the first fading away behind, the 

 second nearly reaching tip of wing, the third beginning below shoulder, shorter 

 than the second, but longer than the third ; each elytrum, besides the blue edge, 

 with a longitudinal vitta between first and second carina, beginning at basal fifth
