[1887]. The specimens differ little, except that some are rather 

 smaller and paler than others, and with conspicuously smaller head." 

 A large series of the various forms of this species from Flying 

 Fish Cove, August-October, 1897, and February, 1898 ; from 

 north coast, December, 1897; and from north part of island, 

 January, 1898. The workers vary from 3-9 mm. in length. 

 The females are 10-1 1mm. long and 22-25 mm. in expanse. 

 They are of a rather darker chestnut- red tlian the workers, and 

 the abdomen is black, clothed with short grey hairs. The wings 

 are yellowish hyaline, with yellowish nervures. The males are 

 7 mm. long and 14 mm. in expanse ; the upper part of the head 

 is black, the antennge and front of the head and face reddish. The 

 thorax is reddish, with brown or black markings, and the abdomen 

 is black, with the sutures light reddish. The legs are reddish, with 

 black femora. Workers found in a rotten stump.

Long. Corp., J 7, 9 10 mm-; exp. al., (5" 11, 9 17 mm. 



Black, head and thorax thickly and finely punctured, clothed 

 with a very fine silvery pile, especially on the face, scutellum, and 

 abdomen ; middle and liind tarsi more or less reddish in the female, 

 and hind tibise edged within with silvery pile ; scutellum oval, 

 much longer than broad, thickly, coarsely, and very irregularly 

 rugose-punctate, wings brownish hyaline, with brown nervures. 



jSTine specimens, from Flying Fish Cove, August-October, 1897 ; 

 east coast, September, 1897; north coast, 1898. 



Apparently identical with a specimen marked " Larrada alecto, 

 Smith," from Celebes; but as we have no authentic specimens of 

 that species from Singapore, the original locality, I am not certain 

 that the Christmas Island insect is the true alecto.
