Ocelli sapissime duo aut ires. Pronotiim inconspicuum. Mesonoti 

 scutum indivisum. Areola discalis nulla. 



Body generally small, elongated, nearly bare, often straightened in 

 the middle. Head small. Eyes lateral, round or oval. Ocelli two or 

 three, rarely none. Proboscis very generally short, long in Gnoriste. 

 Palpi extended (retracted in Coryuocera), incurved, cylindrical, with 

 three or four joints, the first very short. Antennae 10-16-jointed, 

 porrect, simple, pectinated in Phdyroptilon. Thorax convex. Pro- 

 tiotum inconspicuous. Scutum of the mesothorax undivided. JFings and 

 halteres complete, none in Epidapiis ; discal areolet ivanting. Abdomen 

 often compressed, with seven segments, eight in Corynocera. Legs of 

 moderate length, rarely long ; coxce most often long ; tibise generally 

 with spurs at the tips. 



The Mijcetophilida generally inhabit woods, and their larvse 

 mostly feed on decaying vegetable matter. The body is generally 

 compressed ; the legs formed for leaping ; the coxaj lojig, and the 

 tips of the tibiai armed with spurs. The typical genus, Myceto- 

 phila, and especially M. nigra, has much resemblance to the Pn- 

 licidce, whilst the last genus, Bol'itopldla, is closely allied to the 

 Tlpiilidce, by means of Dura and Trichocera. 



The genera may be arranged according to the following syn- 

 opsis : — 



a. Tibiffi armed with spines. 

 h. Mouth not produced. 

 c. Abdomen compressed. 



d. Antennse rather slender, of moderate length. 1. Myceto- 



PHILA. 



d d. Antennae short, stout. 



e. Subapical and subanal veins simple. 3. Azana. 



e e. Subapical and subanal veins forked. 2. Coedyl.\. 

 c c. Abdomen not compressed. 

 d. Wings with one cubital areolet. 



e. Subcostal vein short. 4. Leia. 



e e. Subcostal vein rather long. 5. Boletina. 

 d d. Wings with two cubital areolets. 



e. Middle ocellus very minute. 6. Sciopuila. 



e e. Ocelli of nearly e([ual size. 7. Tetrac.oneuk,\. 

 b b. Mouth produced into a rostrum. 8. Asindulum.
