Spongovostox berlandi* new species (Plate XIII, figure 4.) 



This species bears Vostox hrunneipennis (Serville) a general super- 

 ficial resemblance. The males at hand are, however, readily dis- 

 tinguished by the cheeks, which are longer than the eyes; the teg- 

 mina, which are keeled; the femora, which are suffused proximad; 

 the pygidium of generally similar form but more declivent, with 

 disto-lateral oblique margins much more transverse and not at all 

 emarginate, and forceps, which show a greater inward curvature 

 distad and have the larger tooth of the internal margin proximad, 

 not at the end of the proximal third. 



Type: d^; Guatemala City, Guatemala. [Paris Museum.] 

 Size medium for the genus, form weakly depressed. Head show- 

 ing a moderate depression from eyes to median point of caudal 

 margin, occipital lobes prominent, so that cheeks are longer than 

 eyes and caudal margin of occiput broadly angulate emarginate, 

 sutures obsolete. Antennae with first joint moderately large, 

 broadening so that the distal two-thirds are the more ample; second 

 joint minute; third nearly as long as first, but much more slender; 

 fom'th half as long as third, slightly longer than greatest width; 

 fifth intermediate in length between third and fourth; sixth as 

 long as third. Pronotum very slightly longer than caudal width, 

 smooth, showing a very weak medio-longitudinal linear sulcus, 

 lateral and caudal margins showing a very slight convexity, the for- 

 mer showing a very feeble convergence cephalad; prozona tumid, 

 metazona weakly concave proximo-laterad and very feebly convex 

 mesad, elsewhere deplanate. Tegmina smooth, with a very fine 

 but distinct and percurrent keel along the external margin of the 

 dorsal surface, transverse truncate caudad. Wings fully developed, 

 exposed portion about two-fifths as long as tegmen. Abdomen 

 with dorsal surface polished but microscopically punctulate, fourth 

 and fifth tergites showing laterad a weak rounded carina, these 

 tergites there slightly produced caudad. Ultimate tergite very 

 weakly depressed meso-caudad, caudal margin almost evenly trans- 

 verse. Pygidium very strongly declivent, with surface in a broad 

 triangular dorsal area deplanate, thence convex; lateral margins 

 fitting forceps tightly, latero-caudal margins very strongly conver- 

 gent, almost transverse to a broad, weakly produced median portion 

 which is truncate. Forceps elongate, showing a very feeble curva- 



^We take pleasure in naming this interesting species in honor of Monsieur 

 Lucien^Berland, Curator of Insects of the Museum National d'histoire Naturelle, 

 Paris.
