Gargara pygmaea Walk. 



Centrotus pygmaeus Walk., List Horn. Brit. Mus. (1851), 630. 

 Gargara pygmaea Banks, Phil. Journ. ScL, Sec. D (1910), 5, 48. 



I have seen the material which C. S. Banks determined as 

 G. pygmaea and believe this determination to be correct. The 

 specimens do not agree w^ith the original description as v^^ell 

 as might be desired in some minor respects, but on the whole 

 they answer Walker's description. The specimens which I have 

 seen, however, are all decidedly black, with only a tinge of 

 brown or ferruginous around the anterior and ventral regions, 

 while the original description would have them brown. 



This species is very near G. luconica Fairm., as I determine 

 that species, but is smaller, and the tegmina are shining black 

 and not dull opaque. In both species the tips of the tegmina 

 are more or less hyaline. 



The specimens bear Professor Baker's duplicate Nos. 3951 

 and 2656. 



Very small, black, and shining; posterior process straight and 

 sharp; tegmina glistening black for basal four fifths with tips 

 hyaline. 



Head about as long as wide, finely and densely punctate, not 

 pubescent ; eyes red-brown ; ocelli very small, much farther from 

 each other than from the eyes and situated above a line passing 

 through center of eyes ; front of head not greatly deflexed, almost 

 perpendicular, front convex; clypeus extending below margin 

 of face. Pronotum strongly sloping backward from head, black, 

 finely punctate, very sparsely pilose; median dorsal carina dis- 

 tinct behind humeral angles, but obsolete and only obscurely 

 visible before them; humeral angles not prominent; posterior 

 process subtriquetrous hardly reaching internal angle of tegmina. 

 Tegmina glistening, very dark brown or black for basal four 

 fifths, apex hyaline; base black and punctate; veins prominent. 

 Legs and undersurface of body black; tarsi flavous. 



Length, 2.5 mm. ; maximum width, 1.2 mm. 



Philippine Islands (Walker, Banks) ; Palawan, Puerto Prin- 

 cesa; Luzon, Mount Banahao {Baker).

Rather large, black, robust, without percurrent dorsal carina. 

 Tegmina translucent smoky ferruginous with base and large 

 part of costal area black and punctured. Posterior process 

 strong, sharp, somewhat decurved.
