nized at once by its distinctive form, with tegmina not surpassing 

 the apex of the abdomen, and the type of the male genitalia. 



Type: d"; Para, State of Para, Brazil. (C. F. Baker.) (Acad. 

 Nat. Sci. Phila., Tj^e no. 5317.) 



Size very small: form elongate elliptical; surface moderately 

 polished, sparsely pilose, more heavily so on the limbs. Head ex- 

 posed cephalad of the pronotum for the greater portion of its width; 

 interspace between the eyes moderately broad, very faintly less than 

 that between the ocelli, which latter are ovate : antennae one and one- 

 half times as long as the body, closely moniliform, proximal joint 

 faintly shorter than the interspace between the eyes: palpi with the 

 third joint simple, the fourth elongate funnel-shaped, slightly shorter 

 than the third joint, fifth joint moderately inflated, greatest depth at 

 proximal third. Pronotum weakly transverse, the greatest length 

 contained one and one-third times in the greatest width and the 

 latter placed faintly caudad of the middle, general form subtrapezoid ; 

 cephalic margin broadly subtruncate, rounding laterad into the lateral 

 margins, which are moderately diverging caudad, faintly arcuate on 

 cephalic two-thirds, thence sharply arcuate to the obtuse caudo- 

 lateral angles; caudal margin arcuato-truncate : disk moderately 

 deplanate, with distinct diverging sulci; narrow lateral portions 

 distinctly deflexed. Tegmina surpassing the apex of the abdomen 

 by less than the length of the pronotum, lanceolate: costal margin 

 moderately arcuate proximad, thence nearly straight to the narrowly 

 rounded apex, which is costal in position; sutural margin straight, 

 except for a short proximal section and distad rounding into the 

 strongly oblique, arcuato-truncate, distal margin: marginal field 

 very narrow, in length nearly equal to two-fifths of the entire tegmen : 

 anal field elongate pyriform, in length equal to about one-half of the 

 tegminal length: costal veins fourteen to fifteen in number; discoidal 

 sectors longitudinal, six in number, with distinct, longitudinal, inter- 

 calated nervures and regularly placed transverse nervures, which 

 form rectangulate interspaces; anal sulcus sharply curved distad and 

 joining the sutural margin at a right angle; axillary veins closely 

 placed, with regular intercalated and cross nervures, their structure 

 merged to such an extent that a count is not warranted. Wings 

 falling slightly short of the apex of the tegmina when in repose, great- 

 est width contained one and two-thirds times in greatest length: 

 •costal margin regularly arcuate; apex broadlj^ rotundato-rectangu- 

 late; peripheral margin more amply arcuate distad than usual: an- 

 terior field relatively'' very broad; intercalated triangle distinct but
