the posterior margin broadly evenly incurved, fully exposing 

 the large scutellum, the lateral carinse complete and strongly 

 curved. The pronotum and scutellum, and the tegmina partly, 

 have the same type of large pits as in Signoretia, each pit 

 having a setigerous tubercle within, although in this case the 

 pits are more distant and without sharp rims, the surface be- 

 tween them being smooth and shining, but without leaving a 

 smooth median line on the pronotum; disk of pronotum slightly 

 ridged along the median line, anterior area at sides only with 

 narrowed depressions behind the eyes, these depressions occupied 

 by yellow extensions from the lateral margins. The scutellum 

 longer than wide and longer than the pronotum, posteriorly 

 with a strongly impressed transverse line. Tegmina with veins 

 less prominent than in Signoretia, all pit-hiargined, distally 

 more weakly so ; basal half of clavus and corium within at base 

 sparingly pitted. In all the present material the fourth apical 

 cell is confluent with the single anteapical cell. The subgenital 

 plate (fig. 4, c) of the female is tranverse, truncate posteriorly, 

 and about twice the length of preceding (strongly bent down- 

 ward in the figure) . The subgenital plate of male is of similar 

 form, the gonapophyses are long, narrow, and heavily spined, 

 the lateral plates without curved tips and weakly haired. The 

 hind tibise are prismatic and heavily spined as shown in fig. 4, 

 /, although still another row of spines exists on the opposite side. 

 This species is described from several specimens taken at 

 Puerto. Princesa, Palawan Island, P. I., and is named for Dr. 

 L. Melichar, author of many monumental works on the Homop- 

 tera. (Types in coll. Baker.) 



Pythamus melichari var. mindanaensis var. nov. 



A single male specimen from Iligan, Mindanao, is very similar 

 to the type of P. melichari in general form and coloration, but 

 differs in several secondary details. The lorse are entirely black, 

 whereas in the type the inner margin only is faintly brown. The 

 propleurse are entirely black, and the yellow on the pronotal 

 margins is greatly reduced and without inward extensions. The 

 yellow of the tegmina is also reduced, and a greater portion of 

 the apical area is fuliginous. The genitalia also appear to differ 

 slightly, the gonapophyses being longer and the side plates with 

 tips appressed. On superficial examination this specimen would 

 not be distinguished from the species.
