ments are entirely dark. Also nearly allied, but different by 
the densely punctulate phosphorescent segments, is the fol- 
lowing species. 
82. Photinus (Pyractosoma) punctiventris, n. sp.—Very elon- 
gate, of the same form, size and color as P. nitidiventris, with the sides of 
the prothorax fuscous ; the 1st-4th segments of abdomen are not spotted, but 
fuscous, a little paler at the edges. The phosphorescent segments are finely 
and densely punctulate. The discoidal elevated lines of the elytra are dis- 
tinct. Length 13 mm.; .50 inch. 
Texas; three ¢'; Austin, Mrs. V.O. King; Bosque Co., 
G. W. Belfrage. 
82. Photinus (Pyractosoma) colkustrans, n. sp. — Elongate, 
fuscous. Prothorax yellow, tinged with orange at the middle, a little longer 
than wide, sides parallel behind, regularly rounded into the apex before 
the middle, margins widely reflexed, scabrous; disc sparsely punctulate, 
shining, finely channeled, between the middle and the apex is a transverse 
fuscous spot. Scutellum yellow. Elytra pubescent, coarsely scakrous, 
each with two faint elevated lines; sutural, apical and lateral margin 
narrowly bordered with yellow, side margin narrow, not reflexed. Beneath 
fusco-piceous, 5th and following ventral segments ((j') yellow, 5th and 6th 
phosphorescent, each with a pair of rounded impressions, having a pore at 
the bottom. Antenne fiscous, not longer than the prothorax. Legs fus- 
cous, anterior and middle more or less testaceous. Length 7.2 mm.; .285 
inch. 
Tampa and Enterprise; two o. 
84. Photinus (Pyractosoma) umbratus, n. sp.—Of the same size, 
form, color and sculpture as P. collustrans, but differs by the prothorax 
having an clongate black spot, extending from near the base to the anterior 
scabrous portion, this spot is wider in front than behind ; the elytra are 
more strongly margined at the side. The antenne are longer and more 
slender, extending beyond the base of the prothorax, and the 1st joint is 
pale. Length 7.5 mm.; .30 inch. 
oS 4th and following ventral segments yellow, 4th and 5th phosphores- 
cent, each with a pair of small pits with a pore at the bottom ; 5th broadly 
emarginate behind, 6th small, emarginate, 7th smail, rounded at tip. 
2 The black spot of the prothorax extends to the apex ; the ventral seg- 
ments are black, and only the 4th has a transverse oval phosphorescent 
spot of pale yellow at the middle, the 5th segment is not emarginate, the 
6th is flat, prominent and slightly notched at tip. 
Tampa, Baldwin, Capron; May and June. Two much 
smaller females seem to indicate other species, which with 
more material may be properly defined. It seems to me un- 
safe to propose names for them at present.
