6. Hylotoma bivittata. (Tab. II. fig. 14, $ ; 14 a, antenna; 14 b, head.) 



Lutea, antennis (basi excepta), maculis mesonoti et mesosterni, abdominis apice, genibus 4 posterioribus, tarsis

 Long. 10 millim. 



Hab. Panama, Volcan de Chiriqui, 2000 to 3000 feet (Champion). 



The antennae are as long as the abdomen and are shortly pilose ; the antennal fovea 

 is wide and does not taper much towards the apex. The face below the frontal area 

 is white, the tips of the mandibles piceous, the greater part of the lobes of the meso- 

 notum (except the apex of the middle and the sides of the lateral) and the tegulse are 

 black ; the second recurrent nervure is received beyond the second transverse cubital, 

 but at no great distance from it ; the third cubital cellule is wider at the apex above 

 than on the lower side ; the posterior wings are lighter-coloured than the anterior. The 

 black on the mesosternum forms either one mark or it may be divided into three. The 

 calcaria are black. 



The mesonotum with only the middle lobe is black, the tegulse testaceous, the 

 abdomen with only the two apical segments and the sides of the third black above (the 

 type has the four apical segments completely black). 



The tegulae in the typical form are sometimes fuscous, and more rarely testaceous. 

 The wings, too, differ in the intensity of the tint. 



What I take to be the male has the four posterior tibiae and tarsi black, the extreme 

 apex only of the abdomen and the apex of the middle lobe of the mesonotum are 

 black. 



7. Hylotoma testacea. 



Testacea, antennis (basi excepta), capite, abdominis apice, tarsis tibiarumque apice nigris ; ore facieque inferne 

 pallide testaceis ; mesosterno fusco ; tibiis albidis ; alis byalinis, apice obsoleto violaceo-fuscis, cellula 

 eubitali tertia altitudine breviore ; costa et stigmate testaceis. 



Long. 9 millim.
