MYCETOPHILID^. 



FAMILY II. MYCETOPHILIDJS. 



MYCETOPHILIDA:, Haliday, Ins. Dipt. Brit. 1. 7 (1851); Bigot. Tl- 

 pularite fungicolee p., Latr. ; Meig. ; Mcq. Mycetophilites, Newin. 

 Tipnlidfe cecidomyides p., et T. Mycetophilides p., Westw. Myceto- 

 philinte et Sciarince, Zett. Sciophilinee et Lestreniince, Eond. 



Ocelli sapissime duo aut ires. Pronotum inconspicuum. Mesonoti 

 scutum indivisym. 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 Corynocera), incurved, cylindrical, with 

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

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

 notum inconspicuous. Scutum of the mesothorax undivided. Wings and 

 halteres complete, none in Epidapus ; discal areolet wanting. Abdomen 

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

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

 with spurs at the tips. 



The MycetopkiMda generally inhabit woods, and their larvae 

 mostly feed on decaying vegetable matter. The body is generally 

 compressed ; the legs formed for leaping ; the coxre long, and the 

 tips of the tibiae armed with spurs. The typical genus, Mycelo- 

 p/iila, and especially M. nigra, has much resemblance to the Pu- 

 licidce, whilst the last genus, Bolitophila, is closely allied to the 

 Tipulidce, by means of Dixa and Trichocera. 



The genera may be arranged according to the following syn- 

 opsis : 



a. Tibiae armed with spines. 

 b. Mouth not produced. 

 c. Abdomen compressed. 



d. Antennae 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. CORDYLA. 

 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. SCIOPHILA. 

 e e. Ocelli of nearly equal si/c. 7. TETRAGONEURA. 

 b b. Mouth produced into a rostrum. 8. ASINDI I.IM
