66 INSECUTOR INSClTlit MENSTRUUS 



ish colored rhombus. Occiput covered with flat dark scales ; lower half 

 of sides of head light golden, this color reaching farther up along the 

 eyes, but not to the vertex (the tips of the foremost row of scales shine 

 like tin in a certain light, and a fine nude line around the eye sometimes 

 gives a light impression). A single collar of dark, upright forked scales 

 on the nape ; some black bristles at the lateral margins of the eyes, and 

 few among the scales near the vertex ; of the two coarse bristles at ver- 

 tex in the cingle between the eyes, I found only one with coppery shin- 

 ing tip in one specimen, yet I do not doubt that both will be found in 

 well-preserved specimens. 



Prothoracic lobes rather large, not more remote dorsally than in culU 

 civora, which means relatively (for a Lesticocampa) not far ; vestiture of 

 broad scales, light golden on the lower parts before ; behind and above, 

 as well as the summit dark, shining bronzy ; a row of dark coarse bristles 

 following the anterior margin. Mesonotum coppery brown above, lighter 

 toward the edges, with a dense rough vestiture of broad black scales of 

 a submetallic coppery or bluish luster ; some longer and lighter scaU 

 near the neck. In my specimens bristles are only present at the postero- 

 lateral margins of the disk, where they form a dense fanlike double row. 

 Scutellum narrow, distinctly trilobed ; scales like those of the disk, which 

 also disguise entirely the furrow between scutellum and mesonotum. The 

 scuteUar bristles are not well preserved in my specimen. I find about six 

 insertions in the midlobe, about five short bristles and one long one on 

 the side lobes ; postnotum chestnut brown, with lighter reflection and a 

 dense tuft of black coarse bristles posteriorly. Pleurae and coxae bear- 

 ing silvery scales with a brassy shade. 



Abdomen about twice (or a little more than tv^ace) as long as the 

 standard : 2.5 to 3 mm. in my specimen ; black above with coppery to 

 blue luster, beneath mostly white with a brassy shimmer, the two colors ; 

 separated in a wavy line ; the dark color reaches farther down at the 

 limits of the joints, fading beneath into narrow dark basal bands ; eighth 

 segment entirely dark ventrally ; in the mid-ventral line outstanding light 

 scales ; the first tergite laterally covered with silvery scales ; end of abdo- 

 men with many long blackish hairs, some of them also present on first joint. 



Wings 3-3.25 mm., or 2.5 times the standard; second marginal cell 

 one-third of the wing length, longer and narrower and reaching nearer 

 the base of the wing than the second posterior one ; the stalk of the sec-
