[Vol. V, No. 8, 
widest at lower margin of eye. Snbangulate, converging to clypeus, centra I 
Carina elevated, forked close to the base, lateral carina prominent directed 
outward, clypeus long, tricarinate, antennae very broad, flattened, apical 
portion of second joint pustulate, pronotum broad, lateral carinae very 
widely separated passing from posterior angle of eye to hind border, scu- 
tellum broad, disc depressed, carinae elevated, elytra vitreous, apical 
nervures forked near apex, pustules with very minute setae where visible. 
Color, light straw yellow, front slightly darker with broken, transverse, 
creamy white bars, all carinae light yellow or creamy, scutellum light yel- 
low at apex, elytra vitreous, somewhat infuscated, nervures ivory white 
with minute dark pustules. Apex broadly infuscated and clavus at base 
and apex blackish, transverse bands back of clavus infuscated, all colors 
darker in male, beneath pallid, spines and tarsal claws, black. 
Genitalia — Female pygofers long, carinate on middle; anal style 
flattened, lanceolate. IMale pygofer, truncate, slightly produced medially, 
hooks erect strongly curved at apex. 
Numerous specimens of this rather striking sjjecies were col- 
lected on a shrub, Baccharis halimifolia, near Oyster Bay, 
Aug. 19, 1904. and I have in hand also several specimens col- 
lected bv Prof. J. S. Hine at Bay Ridge, ^I. D. Superficially 
this recalls tricarinata, but the more pallid color is apparently 
constant and the structural characters of the head separate it 
distinctly. In frontal carinae it would seem hardly to fit genus 
Stobaera but the pronotal character agrees so well for that genus 
that it seems best to place it here, provisionally, at least. 
Stobaera minuta. n. sp. 
Similar to tricarinata Say but very much smaller, front dusky between 
eyes only, setae of elytra minute or wanting, apical cloud not so much 
broken. Length of female, .3 mm., male 2. .5 mm. to tip of elytra. 
A'ertex nearly quadrate, fovae rather shallow, anterior one minute, 
front with sides parallel, pronotum shorter than vertex, hind margin con- 
cave scarcely angled at centre. Scutellum with carinae weak, elytral 
nervures, pustulate but not setigerous. 
Color — Vertex yellowish brown, face between eyes brown, sharply 
separated from yellow lower portion. Antennae brown, slightly darker 
than upper part of front, pronotum yellowish brown, a dark spot behind 
eye, scutellum fulvous yellow or shaded brown usually darker on anterior 
part and some specimens with dark brown on lateral portion. Elytra milky 
white, veins interrupted with black points corresponding with the pustules, 
with oblique row of dark spots lying in the discal cells. The smaller 
posterior one within the fork of the second sector, the dark cloud occupy- 
ing about one half of the apical cells, including most of the central cell. 
Beneath light yellow or whitish with dark points on pleurae and black 
points on the legs, claws black. 
Genitalia — J-'emale pygofer narrow behind, plates narrow, ovipositor 
reaching to their tip, anal style short, whitish. Male — pygofer truncate, 
aperture narrowing ventrally and slightly concavely excavated. Hooks 
short, bluntly curved, blackish. 
Described from a large series of specimens including twenty- 
one females and three males, collected by Prof. J. S. Hine at 
Cameron, La., Aug., 1903. Except for certain details of structure 
and difference of distribution of color this species might be taken 
for a miniature form of tricarinata but length of pronotum, color 
of face, extent of elytral clouds and genitalia present very 
oljvious differences which readily separate it.
