ture, which is stronger toward their incurved apices, with a few 

 irregular blunt denticulations proximad on the internal surface 

 particularly along the ventral margin, of which that on the ventral 

 margin opposite the apex of the pygidium is the largest. Penulti- 

 mate sternite simple, its caudal margin transverse, showing a sub- 

 obsolete concavity. Caudal metatarsus with ventral surface well 

 supplied with hairs and with an internal fringe of lamellae, second 

 joint very short. 



Length of body^ 8. and 7.8, width of head, 1.6 and 1.6, length of 

 pronotum 1.7 and 1.7, width of abdomen 2.3 and 2.3, length of for- 

 ceps 3.3 and 3.4 mm. 



Coloration. Entire insect glabrous. Head and pronotum dark 

 chestnut brown, the pronotum laterad becoming chestnut brown, 

 mouthparts and proximal antennal joints ochraceous-tawny, the 

 antennae thence cinnamon-brown. Tegmina chestnut brown. Ex- 

 posed portions of wings warm buff, except distad and along sutural 

 margins where they are chestnut brown. Abdomen dark chestnut 

 brown. Forceps proximad and distad russet, becoming very dark 

 mesad. In the paratype the russet invades the ultimate tergite. 

 Limbs honey yellow, the femora suffused with prouts brown proxi- 

 mad. 



In addition to the type, a paratypic male bearing the same data 

 is before us. 



Spongovostox asemus^ new species (Plate XIII, figure 5). 



This species is in many respects a smaller replica of S. herlandi 

 here described. From that species it is readily distinguished by 

 the tegmina which are not keeled, the more slender abdomen and 

 distinctive male pygidium and forceps which latter have a heavier 

 denticulation of the internal surface with a more conspicuous proxi- 

 mal tooth. 



The form of the pygidium agrees closely with that figured by Burr 

 as of Spongovostox ghilianii Dohrn var.* 



We beUeve that the material examined by Burr represents one or 

 more distinct species. Burr's characterization does not agree with 

 the original description of ghilianii ("pygidium (^ longe productum, 

 postice rotundatim") and his type designation "Venezuela (Mor- 

 itz, Typus von Dohrn) " consequently does not hold. As part at 



^ The measurements of the type are given first.
