GALERUCINE BEETLES — BLAKE 73 



sion in basal half, in the male the antennae 10-jointed and the middle 

 tibiae notched near apex; antennae dark, head, pro thorax, undersur- 

 face, legs (except tarsi), and margin of elytra pale yellow-brown, 

 elytra otherwise piceous. 



Head entirely pale, smoothly rounded over occiput down to the 

 frontal tubercles with an area over tubercles on each side of distinct, 

 closely placed punctures, tubercles not swollen but distinctly marked, 

 interantennal area narrow, not much produced, labrum wide. Anten- 

 nae dark and in male 10-jointed, joints 3-10 long and subequal; 

 antennae in female 11-jointed, the 3d joint short and equal to 2d in 

 length. Prothorax almost as long as wide with sides only slightly 

 curved, a semicircular depression in lower half, entirely pale yellow- 

 brown except in two or three specimens a faint brownish spotting on 

 each side; shining. Scutellum yellow-brown. Elytra smoothly 

 rounded, without depression, shining although alutaceous and with 

 fine, not dense punctures becoming invisible towards apex; piceous 

 with pale yellow-brown explanate margin from apical curve on becom- 

 ing piceous. Epipleura indistinct after middle. Body beneath pale 

 yellow-brown, lightly pubescent; legs pale with tarsi deeper in color; 

 middle tibiae of male notched near apex; tibiae with fine spine at 

 apex; claws appendiculate. Length 3.3 mm.; width 0.9 mm. 



Type: Female, in the LeConte collection, and four paratypes (two 

 males, two females) collected by Belfrage in Texas. In the collection 

 of the U. S. National Museum are 30 more specimens labelled "Texas, 

 Belfrage, Eutopotypes" by H. S. Barber, which are evidently from 

 the same series as the LeConte specimens. 



Remarks: This is one of the species described by LeConte and 

 published after his death by Horn who later synonymized it with P. 

 gentilis, as a color form like P. nigripennis. It is probably a distinct 

 species as the aedeagus is somewhat different and the prothorax has 

 no distinct dark markings as in gentilis, and the elytral markings are 

 unlike either gentilis or nigripennis. I have seen no other specimens 

 besides those taken by Belfrage. 



Genus Oroetes Jacoby 



Oroetes Jacoby, Biologia Centrali- Americana, Coleopt., vol. 6, pt. 1, p. 600, 1888. 

 The original generic description is as follows: 



Head broad, the penultimate joint of the palpi incrassate; antennae filiform, 

 deformed in the male, the second and third joints short; thorax transversely 

 subquadrate, the surface deeply depressed; elytra irregularly punctured, their 

 epipleurae obsolete below the middle; the posterior tibiae with a short spine (this 

 is present on all tibiae) ; the intermediate tibiae notched near the apex in the 

 male; the first joint of the posterior tarsi rather longer than the following thre6 

 joints united; claws appendiculate; the anterior coxal cavities open. 



This new genus, which should be placed near Luperus, is separated from any 

 of the genera composing this section by the broad head and the depressed thorax,
