the type. It is a male labeled "caffra. Coll. Winthem," and "89" 

 on a red tag; also a large blue name label in Doctor Villeneuve's 

 writing, upon which after the name he has written "(caerulea Jaenn. 

 teste Brauer)". As Jaennicke's species was from Abyssinia, I con- 

 clude that hlepharipus is African, and may be dropped from the 

 American list. 



102. PAMMAERUS LEPTOTRICHOPUS Brauer and Bergenstamm 



Sisyropa leptotricJiopa Bbatjer and Beeqenstamm, Denk. Wien. Akad. 

 Wiss., vol. 58, 1891, p. 347. 



Two males on same pin, from " Brasilien " and bearing the Brauer 

 and Bergenstamm label. Undoubtedly the types, although taken for 

 females by the describers on account of the presence of orbital 

 bristles. I designate the species as the type of the following new 

 genus. 



PAMMAERUS, new genus 



Allied to Doiyphorophaga and MuscinotJielaira. Eyes hairy; 

 front broad in male with two pairs of orbitals; ocellar bristles of 

 ordinary size, located rather far forward, so the anterior ocellus is 

 exactly between them ; ocellar triangle large ; paraf acials rather wide, 

 very bright silvery poUinose ; third antennal joint slender, four times 

 the second, with long, thin arista, its basal joints short. Frontal 

 bristles far apart (upper two pairs probably reclinate but missing), 

 the lowest at middle of second antennal joint. Front not prominent, 

 face receding; facial ridges feebly bristled almost to middle. 



Palpi normal, proboscis short, cheek one-eighth the eye height. 

 Thoracic chaetotaxy : acrostichal, 3, 3; dorsocentral, 3, 4; humeral, 4; 

 posthumeral, 2; presutural, 2 (the inner minute); notopleural, 2; 

 supraalar, 3 (stout, flattened) ; intraalar, 3; postalar, 2; sternopleu- 

 ral, 2, 1; pteropleural minute; scutellum with 3 lateral, one small 

 decussate semierect apical, and one small discal. 



Abdomen without discals on second, third, and fourth segments. 

 One small pair median marginals on first segment, one large on sec- 

 ond, a row on third and fourth. Third segment on ventral side with 

 patch of dense, short hairs. Genitalia small. 



Tarsi with minute claws and bristles; middle tibia with a single 

 bristle on outer front side ; hind tibia ciliated, with one bristle below 

 middle of row in one specimen. 



Wings of ordinary structure, first posterior cell open before apex, 

 third vein with 5-8 coarse hairs at base. 



Type of germs. — Sisyropa leptotrichopa Brauer and Bergenstamm.
