 (No. 30 and 37.) One male, two females. 



The present specimens are clearly referable to this species, which 

 was previously known only from the original description. Two facts 

 are evident from the material before us, these being that the species 

 is dichromatic and that the length of the tegmina and wings varies 

 greatly in the same. 



The type was of a greenish color phase, which is almost matched 

 by one of the females in hand, the green of the tegmina apparently 

 being more extensive than in the type, as it colors the adjacent 

 portions of the marginal and anal fields of the tegmina as well as the 

 discoidal as described. The other individuals are of a similar pat- 

 tern, but in several tones of brown with no evidence of green. 



The tegmina show considerable length variation as well as some in 

 the form of the apex of the same. The latter may be acute-angulate 

 without any trace of bluntness or of similar general outline, with the 

 immediate apex narrowly rounded. The wings are described as 

 "dimidise elytrorum longitudinis, " while in one of the present females 

 the wings are about two-thirds of the tegminal length, and in the 

 other they fall but little short of the tegminal apices when in repose. 

 In the male the wings are subequal to the tegmina when closed. 



The measurements of the present material and of the type are as 

 follows :

'5 The specimens from Chapada, Matto Grosso, Brazil, recorded by us as 

 Spathalium cyanopterum (Proc. U. S. Nat. Mus., XXXVI, p. 110), we find on 

 re-examination to be S. klugii (Bm-meister), which Bolivar synonymized under 

 S. serrulatum Thunberg, the type of Burmeister's species having been examined 

 by him. There seems no doubt but that his description of "serrulatum" was in 

 part drawn from this specimen. On examination of the original description of 

 serrulatum we have been unable to positively place the species, but it does not 

 seem to be the same as klugii. Kirby {Syn. Catal. Orth., Ill, p. 298) has given 

 the synonymy correctly and permitted both names to stand. Bruner, unfortu- 

 nately, has redescribed klugii as S. bolivari (Ann. Carneg. Mus., VIII, p. 39). 

 Our material fuUy agrees with his description and that of Burmeister and of 

 Bohvar.
