ABT. 6 NOTES OiST ORIENTAL SAPROMYZID FLIES MALLOCH 35 



As an aid to the identification of the genera most closely related 

 to Trigonoiiietopus I append the key below. All the genera lack the 

 posthumeral bristle. Hendel has altered his definition of this bristle 

 to " presiitiiral bristle " in his later papers.' 



KEY TO THE GENERA 



1. Scutellum louger than half the mesonotum, rouuded quadranguhir, flat con- 



vex, sharply margined and celj'phuslike projecting over base of abdomen 



Celypholauxania Hendel (Neotropical). 

 Scutellimi normal, not margined nor prolonged 2. 



2. Postvertical bristles lacking ; face with a vertical central keel which is quite 



sharp on upper part ; anterior orbital bristles incurved. 



Sauteromyia Malloch. 

 Postvertical bristles present; face not keeled 3. 



3. Anterior orbital bristles incurved Paranomina Hendel. 



Anterior orbital bristles recurved Trigonometopus Meigen. 



Sauteromyia is known only from Foimosa, and Paranomina from Australia. 



MAQUILINGIA, new genus 



Genotype. — Maquilingla hirticeps, new species. 



This genus is one of the few in the family in which the dorsocentral 

 bristles are arranged 1 + 2. From the others occurring in the Orient 

 in which the costa is similar to that of Bapromyza it may be dis- 

 tinguished by means of the key presented below. The general appear- 

 ance is quite similar to that of Paranoniina Hendel, but the post- 

 humeral bristle is present, and consequently it falls in the section 

 containing the Australian genus Trigonometopsis Malloch and the 

 Old World genera included in the following key. 



EBY TO ODNEEA 



1. Thorax with the anterior pair of dorsocentral bristles in front of suture, and 



but two postsutural pairs 2. 



Thorax with the anterior pair of dorsocentral bristles at or behind suturp, 

 and always three postsutural pairs thus present Trigonometopsis Malloch. 



2. Thorax with quadriseriate intradorsocentral hairs ; postvertical bristles wel! 



developed ; anterior orbitals not, or very slightly, bent inward ; frons 

 longer than wide, copiously haired in front Maqiiilingia, new genus. 



Thorax with biserate intradorsocentral hairs ; anterior orbitals bent in- 

 ward S. 



Thorax with biseriate intradorsocentral hairs; anterior orbitals not bent 

 inward ; frons as wide as long, sparsely haired, inner verticals longest. 



Kerteszomyia, new genus. 



3. Postverticals very small and weak, far below the ocelli. 



Panurgopsis Kertesz, 



Postvertical well developed, in normal position frons fully as wide as long. 



with few hairs in front Chaetolanxania Kerto^z.
