Phasmophaga has a brownish-yellow egg, the chorion appears 

 not to possess any reticulation and is not punctulate; the sur- 

 face appears to be quite smooth. 



TD 390 (Mass.) is a small fly with a disproportionately long 

 uterus; it has much the habitus of Eusisyropa, and has been 

 determined by Mr. W. R. Thompson as Masicera sp. near 

 pauciseta. The egg is deeply yellow with a slight brownish tinge, 

 the chorion is reticulate with nearly perfect hexagons, and the 

 surface is sparsely set with long chitinous spine-like points which 

 look like short hairs growing therefrom. No punctulation. 



TD 35.3 (Mass.) was at first determined by me as Eusisyropa 

 blanda and so published in Tech. ser. Bull. 12 Bur. Ent., p. 

 116. I doubt if it is that genus. It contained some TOO whitish 

 eggs in the uterus, which was thus probably of the short thick 

 type. These eggs show the nearly mature maggots within. 

 The chorion is thin, without reticulation or punctulation, and 

 has much the appearance of the Phasmophaga chorion exter- 

 nally. 



Finally, TD 747, a small yellow-legged fly with a pseudo- 

 dexiine habitus and a very long slender uterus, from Ocean 

 Beach, South Florida, shows black eggs whose chorion appears 

 very similar to that of Phasmophaga in structure. There is no 

 punctulation or reticulation, and practically no appearance of 

 rugosity, the surface being quite smooth. Filaments of trans- 

 lucent substance appear to depend from the ventral surface 

 of this egg, showing in every one of many mounted specimens 

 as pendulous loops and coils. I have seen nothing of the kind 

 in any other egg. They are perhaps intended for more secure 

 attachment to leaf surfaces. 



These examples might be multiplied, but I have given suffi- 

 cient to show the wonderful diversity of type exhibited by these 

 minute-egg forms, all of which are believed to oviposit upon the 

 foliage of the plants.

Eumyobiine series — Eumyobia flava gen. et sp. nov. (Peru) 

 dissected and drawn, TD 4021. Ovaries large, oviducts short, 

 common oviduct long, spermathecal ducts and tubular glands 

 short, preuterus present; uterus very heavy and thick, in two 

 stout coils or so, the elongate maggots developing therein. 

 The eggs and maggots are packed in irregularly, in various posi-
