diameter, than in sericata. Sides of ventral part of occiput 

 and adjoining part of the bucca with a white beard. Anterior 

 part of thorax by oblique light looks thickly white pollinose. 



I have one specimen, male, New Bedford, which I refer to 

 L. caesar L., because I can find no structural difference whose 

 squamula thoracalis is blackish brown and whose halteres are 



whitish at base of peduncle, the 

 rest of the peduncle and the knob 

 being blackish. 



I offer the following suggestions 

 as to the synonymy of some of 

 the species of Liicilia recorded in 

 Osten Sacken's Catalog. : L. brjmnicosa Desv. 

 is '^xQ\id\Ay sylvarnm Meig. ; carolinensis Desv., 

 conipar Desv., and Heraca Walk, are Pseiido- 

 pyrellia cornicina Fabr. ; coiisobrina y[2icc\., fratci-Jia Macq., and 

 lepida Desv. are caesar L.; caeruleiviridis Macq. and ^crj// Jaen. 

 are sericata Meig. ; fiilvifacies "Dtsv., philadelphica Desv., terrae- 

 novae Macq., inollis Walk. (.'*), riifipalpis Jaen., and stigrtiaticalis 

 Thoms. are all regiiia Meig., as are also the following, described 

 by Bigot in Bjtll. Soc. Zool. Fr., 1887, — Sovioinyia rcctinervis, 

 S. rufigena, and 5. riipicola. Liicilia regina Meig. is the type 



I the genus P/ionnia 

 Desv. L. terrac-novac 

 Desv. is P ho rm i a 

 groenlandica Zett., and 

 Desvoidy's name has 

 priority (perhaps this 

 is P. caeriilea Desv.). 

 PJwTViia. — P. regina 

 Meig. very common everywhere (Fig. 9). 

 Dull metallic green usually, but subject 

 to the usual variations of metallic-colored 

 Calliphorinae ; legs black ; prostigma red to yellow ; antennae 

 pale brown to black ; frontal vitta pale brown to black ; palpi 

 red to yellow ; squamulae naked, white to yellowish brown. 

 Front of male very narrow, of female about one-third as wide 

 as head. This species seems to be rare in Europe. I am
