PYKKHOPYGE. 249 



Hab. Hondueas (Dyson, in Mus. Brit. 2 ).— Colombia ; Venezuela; Peru 1 and 

 S. Beazil. 



Though very similar to P. zenodorus in outward appearance, and to be distinguished 

 chiefly by the deeper red colour of the head and apex of the abdomen, this species is 

 really very distinct, and in the structure of the male genitalia closely resembles P. scylla, 

 described below, which, again, has external characters of its own. 



P. menecrates was described by M. Mabille from a specimen in the Brussels Museum 

 from Peru. We have a series of examples chiefly collected by Mr. H. H. Smith at 

 Chapada in South Brazil, and there is one in the British Museum obtained by Dyson in 

 Honduras. The latter is our sole authority for including the species within our fauna.

In general appearance this species is very like P. zenodorus and P. zeleucus, but may 

 at once be distinguished by the colour of the head between the eyes, which, instead of 

 being red, is black spotted with white. There are two indistinct glaucous lines down 

 the thorax and a narrow rufous line on the middle of each tegula : these characters are 

 well shown in Menetries' s figure, but the latter is a variable feature and frequently 

 absent without reference to locality. The male genitalia of both forms are precisely 

 alike. 



The range of this species within our region is very similar to that of P. zenodorus, 

 but it hardly goes so far north ; and in Guatemala it occurs in the forest-region 

 bordering the Pacific Ocean. In the southern continent it is not widely diffused and 

 at present we have not traced it beyond Colombia and Venezuela. 



In the structure of the male secondary organs (Tab. LXXIII. fig. 6) P. scylla departs 

 widely from more typical species of Pyrrhopyge. The harpagones are much produced 

 and end in a long serrated decurved rod, there are no prominent lobes attached to the 

 middle of the dorsal edge, and the tegumen is simpler, with a single central point and 

 two abbreviated serrate lobes, one on either side of its base. We have only met with a
