The head has a curious process that projects in front so 

 that the labrum is concealed from above, its front angles 

 are rectangular, but the middle is slightly produced, from 

 the sides it resembles a thin flange, it is not an acute process 

 such as in C. Scutellaria-, so I regard the head as unarmed, 

 and so regarding it the species would be associated with 

 G. guerinij in which the process is ridged along the middle 

 in the male; the antennae are slightly longer (13 mm.) 

 than the body. It belongs to Water house's second section 

 of the genus. 



A specimen from New South Wales (Wentworth Falls, 

 H. J. Carter), possibly belongs to this species, but has the 

 dark part of the elytra advanced to the basal fourth, the 

 front femora with more numerous teeth (seven on one of 

 the rows), and the dentition of the front tibiae inconspicuous. 

 Another specimen, from the Madang district of New Guinea, 

 possibly also belongs to the species, but the dark part of the 

 elytra has a deep metallic-green gloss, and leaves only the 

 basal fifth pale, the denticulation of its front legs is as on 

 the Wentworth Falls specimen. 



Luciola cowleyi, Blackb. 



Some years ago I received from the late Rev. T. 

 Blackburn a specimen bearing his name — label "Luciola 

 cowleyi, Blackb.," but without a locality label; this specimen 

 agrees well with the description, except that parts of two 

 abdominal segments are white; whereas in the description 

 only the penultimate segment was noted as white; on some 

 specimens with the apical segment contracted, however, its 

 white part is scarcely distinct from that of the preceding 

 segment, so that possibly he was misled, or the type may 

 have been a female (unknown to me) with really only one 

 segment white. There are numerous males in the Museum, 

 from the Northern Territory, that agree with the specimen 

 above noted, and all of them have the white of the abdomen 

 confined to the lower-surface ; the dark parts of the elytra 

 vary somewhat in intensity of colour, and on some specimens 

 only a small part of the base of each could be regarded as 

 blackish. 



Luciola flavicollis, Macl. 



A specimen, from Normanton, possibly represents a 

 variety of this species; it is larger (6'5 mm.) than usual, and 

 the suture is as widely pale as the sides, but the black covers 

 the whole of the tips; three apical segments of the abdomen 

 are pale, but the two apical ones are more flavous than the 

 other, which is almost white, the apex of the subapical 

 segment is gently but distinctly incurved to the middle,
