large oval area occupying most of the ventral area of the 
seventh abdominal segment. When the insect is calling for 
the male, she curves up the posterior end of the body until 
the luminous area is fully exposed. She seems to move about 
so as to turn the luminous area in another direction, if one has 
not proved successful. While I watched her, three specimens 
of Lamprophorus tenebrosus came down, but they did not 
stay long. No males of her own species came on the first 
night. 
The female is larva-like, softly hairy, slightly flattened 
dorso-ventrally, and tapering from the posterior end of the 
thorax towards the head, which is small and black. There 
are nine broad, dark brown, transverse plates of chitin, one 
on each segment from the metathorax backwards. There is 
a faint, mid-dorsal, longitudinal brown band on the first two 
thoracic segments. The mandibles are narrow, curved, and 
sharply pointed, suggesting an animal diet. The antenne 
are short, and consist of nine segments. The thoracic legs are 
well developed. 
Later in the evening of the Ist, when I looked at the tube 
in which I had placed her, I was astonished to see that she 
was luminous at many points. It is very difficult to make 
an accurate count of the number, as all the points may not 
be luminous at the same time, but there seem to be ten 
transverse rows of four each, two of the four being on the 
dorsal aspect, and two low down on the sides. In the third 
row from the anterior end, that on the first abdominal segment, 
the ventral spot was wanting on one side, and the penultimate 
segment bore three on the dorsum in place of the normal two. 
When the spots are luminous, the large ventral area is only 
faintly so, but there are a few bright points situated round 
its margin. So far as I could make out the spots were situated 
on the segments, the lateral ones being ventrad of the spiracles. 
No males came on the night of the 2nd. 
I exposed the insect on the night of July 3rd towards 7 P.M., 
and she had hardly begun to expose her light when I had 
secured six males. The males are very much smaller than 
the female. They did not show any light, and came running 
along the ground. Later in the evening, in confinement, they,
