THEODORE H. FRISON V 



Petiole somewhat less than twice as long as distance from point of articu- 

 lation to cephalic margin of proi)odeum; with oblique carinae on lateral aspect 

 and longitudinal cai'inae on dorsal aspect, interrupted by small punctures 

 on dorsal as])oc(.; with sparse sui)pressed setae. Abdomen c()ini)resse(l, 

 polished. 



Closely related to //. si milt s Szepk^geti, from Brazil. 

 One specimen, the holotype, collected on October 9, 1919, 

 at Parintins, Brazil. 



Hyptia splnifera new species 



Male. Length, .5.5 mm. 



Head, scape, j)edicel, thorax, propodeuni, petiole, legs, c\'ce])t darker 

 distal portion of the hind pair, light-ferruginous. Flagellum, dentes of man- 

 dible, abdomen, exclusive of the petiole, black. 



Head below antennae moderately punctate, with two elevated, impunctate, 

 oblifiue faintly striated carinae, interval between the carinae with a row of 

 large punctures; face separated from malar space by the outer of the (wo 

 carinae; occipital orbits over twice as broad below as above, exee])ting the 

 two rows of large ))imctures adjacent to the eyes, but sparsely and moderately 

 punctured; malar s])ace somewhat less than one-half as long as length of eyes, 

 about three-fifths the length of scape; mandibles weakly punctate, polished. 

 Head above antennae nearly flat, coarsely punctate, the i)unctures much 

 larger than those below; area behind ocelli punctate. Head viewed from 

 above broader than thorax, transversely subquadrate, about twice as jjroad 

 as long, but slight)}' convex in region of antennal fossae; viewed from fi-ont 

 with vertex weakly rounded, eyes slightly obli(]U(^; ocelli arranged in a triangle, 

 lateral ocelli twice as far apart as distance from inner margin of eye; setae 

 erect, light-colored. Antennae inserted below mitldle of eyes, densely seta- 

 ceous, flagellar segments of nearly equal thickness throughout; scajjc with setae 

 longer than on flagellum, finely punctate, length slightly over twice; the dis- 

 tance from its articulation to inner margin, of ey(;, slightly longer than pedicel 

 and first two flagellar segments combined; i)edicel one-half as long as first 

 flagellar segment; sc^cond and third flagellar segments of equal length. 



Alitrunk about one-third again as long as broad, somewhat longer than 

 high; numerous erect, golden setae on dorsum and venter. Pronotuin not 

 forming a collar visible from above, humeral angles slightly angular. Meso- 

 scutum without ])arapsidal grooves, lat(>ral grooves weakly formed, with 

 rather numerous, large, rounded punctures. Mesoscutellum impressed along 

 cephalic margin with a transverse row of deep, very large ])unctures; remainder 

 of area, except for a small, median, impunctate, jjolished s[)()t, with large 

 punctures. Mctanotum narrow, moderately depressed, coarsely punctate. 

 Propodeiun ccphalad of articulation of ])etiole, except at very base of petiole, 

 coarsely pimctate, sharply limited on each side by reticulations of lateral 

 asjjcct. Pro])leura mostly polished and impunctate. Me.sopleura witli 

 dorsal half jjolished, im[)unctate; cei)linl()-dorsal angle with (wo large, shallow
