nations result, the male parts being anterior, and the female 

 posterior, or vice versa ; this is of rare occurrence, and has been 

 noticed only in a kind of ichneumon. 



Crossed Gynandromorphism is when each side of the body 

 presents at the same time the characters of the two sexes. This 

 combination is rare, although much less so than the jDreceding. 

 It has been observed in a Bombyx. Castrensis, in which the left 

 antennae and the right wings were female, and the right antennie 

 and the left wings male.

The Parasol or Leaf Cutting Ant. 



It may be interesting to members of the Club, to learn 

 that I have two Parasol Ants' nests on a table in my house, and 

 that I have fed them for some weeks. The nests have there- 

 fore been easy of supervision, and very accessible for observing 

 these ants' habits and their method of life. 



I propose in this paper to refer only to the treatment the 

 leaves receive, after they have been carried into the nest. 



We in Trinidad, who are interested in such subjects, well 

 know the hurried manner with Avhich a parasol ant returns to 

 her (all leaf cutting workers are females) nest, bearing erect in 

 her mandibles, the portion of leaf she has herself just cut off", 

 and is apparently running home with it in triumph. 



These foragers, for they are the ones who supply the house- 

 hold, carry their portion of a leaf well into the nest, drop it, 

 and retufti for another piece, nor do they cease doing so, till the 

 supply is more than those in the nest require. 



I could not induce the ants in one of my nests, " B," after 

 its capture, to carry any leaf whatsoever into the nest, till one 

 day I coaxed a small worker to do so, as she entered she was 

 caressed by those in the nest, who stroked and patted her with 

 their antenna?. The small piece of leaf she had brought was at 

 once taken by one of the larger workers, to go through its various 

 processes, Avhile she returned for more, and she continued to 

 bring in pieces till late in the evening. Strange to say, none of 

 the others followed her example. Even now, four weeks later, 

 only two or three cany in any portions of leaf, indeed the nest 

 is very inactive oa that score. It may be that there is no queen 

 as she was accidentally killed while taking the nest.
