296 ENTOMOLOGICAL NEWS. [December, 



Males, females and larva were found, the latter also showing- 

 light. 



During the early flight in the evening Pkoturis frontalis was 

 taken, but not on the low salt grass. On one of my previous 

 trips to this island Photinus consanguineus , P. ardens and two 

 forms of Pkoturis frontalis were taken. Pyractomena was care- 

 fully sought for during the day, but not a specimen was taken. 



The following are some of the larval characteristics: Length 

 .75 inch. ; 19 mm.; fusiform, greatest width .20 inch.; 5 mm.; 

 depressed and flattened above. Color deep sulphur-yellow, with 

 a slight rosy tint on the thoracic segments, as in the imago; 

 upper surface with a smoky-brown stripe on each .side of the 

 middle, broadest centrally and attenuating at each end. Body 

 beneath with similar stripes on the thoracic and extreme sides 

 of the abdominal segments. The surface above is well marked 

 with large shallow punctures. On the first to the fifth abdominal 

 segments are lateral lobe-like projections from the side. Legs 

 short, quite stout, with a single tarsal claw. Head, at first sight, 

 seems entirely wanting, soft in texture, except for the mouth 

 parts, enveloped in a membranous tube, which, when the head 

 is extended, forms a long flexible neck. 



The insect is able to withdraw its head from sight as completely 

 as any snail or turtle; mandibles yellow, fairly well chitinized, 

 pointed, with short divergent hair near the base; antennae short, 

 two-jointed, with a button-like tubercle, which may represent a 

 third joint. The basal segment is not defined and partly envel- 

 oped in membrane. A single ocellus on each side of the head 

 behind the antennae is not easily seen; the other mouth parts are 

 proportionately small, and best described by the figure.
