examination of the original material of hebes will, in all probability,

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

 Nat. Sci. Phila., Type no. 5316.) 



Size very small: form moderately depressed: surface moderately 

 polished, of the head, pronotum, tegmina and limbs with sparse, 

 but distinct, erect hairs. Head for its full width visible cephalad 

 of the pronotum, the outline of the e3'es and occiput regularly 

 arcuate; interspace between the eyes very broad, equal to one and 

 one-half times the depth of the adjacent portion of the eye: ocelli 

 elliptical, oblique in position, the interspace between them subequal 

 to that between the eyes; palpi with the third joint slightlj" longer 

 than the fourth, fifth appreciably longer than the third and moderately 

 inflated, excavate face obliquely truncate for the greater portion 

 of the length of the joint: antennse faintly exceeding the body in 

 length, rather sparsely but regularly setose. Pronotum subtrapez- 

 oid in outline, the greatest width, which is distinctly caudad of the 

 middle, contained one and one-half times in the greatest length of the 

 same; cephalic margin moderately arcuate, rounding into the but 

 weakly arcuate, diverging lateral margins, caudo-lateral angles well 

 rounded, caudal margin moderately arcuate, all the margins dis- 

 tinctly though narrowly cingulate: in transverse section the disk is 

 flattened dorsad and distinctly and roundly declivent laterad; sur- 

 face unimpressed. Tegmina lanceolate-elliptical, the greatest width 

 contained slightly more than three times in the greatest length of the 

 tegmen, distal section surpassing apex of abdomen by nearly the 

 dorsal length of the pronotum: costal margin moderately arcuate 

 proximad and distad; sutural margin in greater portion straight, 

 distad regularly arcuate to the broad and well rounded apex, which is 

 more costal in position: marginal field relatively narrow and abbrevi- 

 ate ; anal field elongate pyrif orm, reaching to two-fifths the length of 

 the tegmen: discoidal vein with sixteen costal rami, several of the 

 clistal ones of which are bifurcate; median vein with four rami (made 

 up by bifurcation of two main rami) ; ulnar vein with three to four 

 rami, the number of both median and ulnar rami very difficult to 

 determine owing to the anastomosing of the veins in the proximal 

 portion of the discoidal field; anal sulcus regularly arcuate in proxi- 

 mal half, straighter distad except for the short distal arcuation near 

 the junction with the sutural margin; axillary veins fourteen in 

 number, as the usually weak adventitious veins are equal in strength 

 to the usually more pronounced principal veins. Wings with the
