162 Phoridae. 



bristles nearly confluent witli a row of a little longer genal bristles; 

 the other species have small oral bristles or hairs, but no genal bristles, 

 only in citreijormis and vitripennis there is one oral bristle and in 

 the former two in the latter one genal bristle, all somewhat conspi- 

 cuous; in these two species the jowls are also a little descending. 

 Thorax with one pair of dorsocentral bristles; scutellum with two or 

 four bristles, in the latter case the anterior always much smaller 

 than the posterior. The dorsopleural suture is generally somewhat 

 efTaced anteriorly and, therefore, the upper part of mesopleura shows 

 a pubescence similar to that on the disc; in one species, mordellaria, 

 the mesopleura have a long and strong bristle behind; only in two 

 species, citreijormis and vitripennis, the dorsopleural suture is present 

 in its whole length and mesopleura not hairy above. Abdomen some- 

 what robust, second segment more or less elongated, and sometimes 

 also sixth. Hypopygium small and of a construction characteristic 

 of the genus; it is always symmetricai, the difference in construction 

 from the other genera consists therein that the opening for the anal 

 tube is not between the side-prolongations from the tergite, but this 

 opening pierces the tergite itself; I think, however, that the difference 

 is not a principal one, but caused by a secondary uniting of the side- 

 prolongations below the opening for the anal tube; all the hypo- 

 pygia I have studied have given me this impression, and the junction 

 is often very short as in incrassata, or somewhat fissured in the middle 

 as in mordellaria; in citreijormis the hypopygium is of the common 

 construction, with free side-prolongations; the anal tube is short, 

 papilliform, or, what is most often the case, it does not protrude; 

 there is a large, more or less deeply cleft or excised ventral plate; the 

 parts of a complicated subanal body always protrude more or less. 

 In the female abdomen in some species (incrassata, carinijrons) ends 

 with a shorter or longer, tubiform segment with small lamellæ at 

 the end, but generally it only bears at apex two small lamellæ. Ab- 

 domen is very short-haired, only at the sides of first and second 

 segments there may be longer hairs, and often also on sixth segment. 

 Legs in many species rather robust with the femora, especially hind 

 femora, broad, the tibiæ strong and sometimes the front tarsi in the 

 male broad or with the last joint broad; in other species the legs 

 more slender; otherwise the legs are somewhat various in the various 

 species; front tibiæ with one, sometimes very weak dorsal bristle, 

 but in some species with more, middle tibiæ with a pair of bristles 

 at about the upper third and one, sometimes weak, anterior at apex
