STKONGYLOGASTER. 9 



the second cubital cellule is much narrower and longer than the third, and has a 

 fuscous horny point ; the costal cellule has a larger black horny point ; the transverse 

 median nervure is received a good piece before the middle of the cellule. The black 

 basal portion of the wing ends before the termination of the costal cellule and at the 

 horny point ; the black apical part commences before the apex of the stigma. The 

 accessory nervure in posterior wing is shortly appendiculated. The apices of all the 

 tarsi (but especially the posterior) and the apex of the hinder tibiae are black. The 

 claws are bifid. 



This species is not unlike S. maculipennis, but is easily known from it by the third 

 cubital cellule being shorter than the second, the opposite being the case with S. maculi- 

 pennis, by the apical half of the antennas only being black, the fifth, sixth, and seventh 

 joints not being produced at the apices ; the face has less white, and the thorax less black ; 

 the apex only of the tarsi is black ; and the transverse median cellule is received nearer 

 the base of the cellule. The head, too, is much longer. 



10. Strongylogaster maculipennis. (Tab. I. f. 8, $ .) 



Niger, nitidus, pilosus, facie *alba ; pronoto, metapleuris, abdomine (apice excepto) pedibusque luteis ; tarsis 



posticis tibiarumque apice nigris ; alis fuscis, medio navo-hyalino, stigmate et costa flavis. 

 Long. 9-10 millim. 



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



The antennas have the two basal joints luteous, pilose, thickened from the fourth 

 joint; the apex of sixth, seventh, and eighth produced into a blunt point beneath, more 

 especially the sixth. The face from below the frontal area is white. On the thorax 

 the greater part of the mesopleura and sternum are black, as is also the meso- and 

 metanotum, except the angles of the lateral lobes. Wings with extreme basal part 

 of costa luteous, the rest to near the stigma black; the transverse radial nervure 

 is received near middle of cellule; the bullae and spurious veins as in S. pilicomis; 

 transverse median nervure received a piece in front of middle of cellule; the third 

 cellule longer than the second, which is considerably angled where the recurrent nervure 

 is received in front of middle of cellule. The apical fuscous cloud commences at the 

 end of stigma ; the basal one ends a little in front of median cellule ; there is a small 

 fuscous cloud at end of lanceolate cellule. In the hind wings the basal cloud is 

 narrower than in front wings ; there is a fuscous mark below the apex of anal cellule. 

 The middle tarsi have the four apical joints black. In the second cubital cellule 

 characteristic is the large horny point. The mesopleurse are sometimes nearly all 

 yellow. The vertex is raised ; but the sutures are depressed equally to the eyes ; the 

 frontal area is not well defined. The lateral fovese are small, and raised in the centre ; 

 the front is depressed considerably; the central fovea small but deep, and broader 

 than long.
