wings are truncate distad, with immediate apices showing very 

 slight production. 



It is clear that moulioni is very close to oligoneura and may prove 

 to be a geographic race. Giglio-Tos' insularis, from the superficial 

 description, is apparently even closer to oligoneura and may repre- 

 sent a geographic race, but more probably an absolute synonym 

 of that species.

 greatest pronotal width, 0^2.4, 9 2.9; length of tegmen, 17.6, 9 21.2;

These specimens have been correctly recorded by Rehn.«- The 



measurements are: length of body, 6^21, 9 26; length of pronotum, 



cf 6^, 9 7.4; greatest width of pronotum, d^ 2.1, 9 2.7; length of 



tegmen, cf 16.2, 9 18.8; width of tegminal marginal field, cf 1.2, 



9 2; width of cephalic femur, cf 1.7, 9 2.1 mm. 



Acromantis luzonica new species. (Plate II, figure 4.) 



This species agrees with A. parvula Westwood^^ in size and in 

 having the apex of the anterior field of the wings arcuate and not 

 showing the truncation indicated to varying degrees in males of 

 the other species known to us. It differs in having no supra-ocellar 

 spine, the pronotal supra-coxal expansion more decided, the teg- 

 mina and wings not surpassing the apex of the abdomen, the teg- 

 mina with all fields equally tinged with green and subopaque and 

 the distal lobes of the median and caudal femora smaller, scarcely 

 half as wide as the tibiae. 



«2 Notes from Leyden Mus., XXXV, p. 126, (1912). 



*^ One of the most unsatisfactory features of Giglio-Tos' work lies in the fact 

 that in his revisionary studies of the Acromantinse he has almost invariably 

 failed to give any additional data for previously described species. Under A. 

 oligoneura (Haan) he places A. parvula Westwood as a synonym, records ma- 

 terial from Java and Borneo, but gives no data whatever concerning the speci- 

 mens recorded or reasons for the sjTionymy indicated. The fact that the apex 

 of the anterior field of the wings as figured by Westwood shows no truncation 

 whatever causes us to believe parvula to be a valid species, which we here recog- 

 nize. Westwood's description is unsatisfactorj% but with his figure far more 

 useful than the descriptions of new species of the genus Acromantis given by 

 Giglio-Tos.
