376 The Ohio Naturalist. [Vol. V, No. 8, 



widest at lower margin of eye. Subangulate, converging to clypeus, central 

 ■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 Ijorder, 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 Avhite 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. Male pygofer, truncate, slightly produced medially, 

 hooks erect strongly curved at apex. 



Numerous specimens of this rather striking species were col- 

 lected on a shrub, Baccharis halimifolia, near Oyster Bay, 

 Aug. 19, 1904. and I have in hand also several specimens col- 

 lected by Prof. J. S. Hine at Bay Ridge, M. 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. 



Vertex 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 Aveak, elytral 

 nervures, pustvilate 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 — ]-"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 

 ■obvious differences which readily separate it.
