ABT. 21 ACALYPTRATE PLIES MALLOCH 19 



MINETTIA GEMINATA (Fabricius) 



A very conspicuously marked yellow species, strildngiy resembling 

 Alloclusia philippi Rondani in thoracic and wing markings. Frons 

 without a dark central line ; face unspotted ; cheek, center of sides of 

 labrum, and apices of palpi, fuscous. Dorsum of thorax with two 

 dark brown vittae which extend to apex of sciitellum; pleura with 

 two similar vittae, making six in all on thorax. Apices of abdominal 

 tergites with black transverse line in center. Apices of all femora 

 and of mid and hind tibiae, fore tibiae except bases, all of fore tarsi, 

 and apices of mid and hind tarsi black. Wings marked as in figure 

 19. 



Ocellars small; arista moderately long-haired. Postsutural dor- 

 socentrals 3 or 4 pairs the anterior two pairs short ; a distinct bristle 

 in line between the intra-alar and supra-alar bristles. Fore femur 

 without anteroventral comb. 



Length, 6-7 mm. ^ 



Many sj^ecimens from Costa Rica. 



Genus PSEUDOGRIPHONEURA Hendel 



Although the genotype of PseudogrlpJioneura Hendel and that of 

 Deceia Malloch differ strikingly in habitus, the former being a very 

 robust species and the latter quite slender, I hesitate to consider them 

 as entitled to more than subgeneric separation. Apart from the gen- 

 eral habitus Deceia has the ocellar bristles strong, while in Pseudo- 

 gri'plioneura these are very small and weak. Accepting these as 

 subgenera we must perforce place all the subgenera accredited to 

 Deceia in the recent paper by W. L. McAtee and the writer under 

 Pseudogriphoneura. I have found several species of this subgenus 

 in the United States National Museum and present a key for their 

 separation herein. 



KEY TO SPKCIES 



1. Legs entirely yellowish white ; wiugs clear ; apices of abdominal tergites 



testaceous yellow pallipes, new species. 



At least the femora black or dark gray 2 



2. Wings with more than the apical half deep brownish fuscous ; fore tarsi 



stouter at apex of first segment and on entire second than at base of 



first ; apices of abdominal tergites not yellow cormoptera Hendel. 



Wings hyaline, without dark cloud 3 



3. Apices of abdominal tergites rather broadly yellowish ; thorax quite no- 



ticeably quadrivittae with brown variata Hendel. 



Apices of abdominal tergites not noticeably yellow ; thorax without ap- 

 parent brown vittae hyalipennis, new species. 



PSEUDOGRIPHONEURA CORMOPTERA Hendel 



This species has a great resemblance to some of those in Grip- 

 honeura^ the similarity being heightened by the very distinctly 

 marked winjrs.
