 trals; one intra-alar ; preapical bristle of tibiae present ; .femora black. 

 (Europe.) Neoalticomerus Hendel. 



CRYPTOCH^TUM Rondani. 



The genus Cryptochartiim is anomalous in any group. The follow- 

 ing species were originally described as Lcstophomis, as a genus of 

 the Oscinidae. The humeral break of the costa, as well as other char- 

 acters, suggests the Milichiinse, but the postverticals are divergent, as 

 in the Agromyzinse alone. The postverticals are inconspicuous among 

 the erect, short, stiff hairs of the vertex, but can be differentiated as 

 a pair of divergent hairs immediately behind the ocellar triangle. 



Penultimate section of the fourth vein one half the length of the ultimate 

 section ; fourth and fifth veins not weakened ; face, front, mesonotum 

 and scutellum deep blue, rather shining ; abdomen shining blue-green ; 

 antennae black, legs blackish ; wings grayish hyaline, veins dark brown. 

 1.5 mm. (Australia, introduced into CaViiorma..) ... Ac ery a Williston. 



Crossveins closer together ; fourth and fifth veins slender beyond the crossvein ; 

 otherwise as in the preceding species. (Australia, doubtfully intro- 

 duced into California.) monophlebi Skuse. 



TRAGINOFS Coquillett. 



Arista almost bare ; lunule white, unspotted ; sides of front cinereous, with 

 setigerous black spots ; thorax similarly spotted, pleurae bivittate, 

 abdomen brown, spotted ; legs yellow, the base of the femora and two 

 rings on the tibiae brown ; halteres yellow ; wings hyaline, with numer- 

 ous rounded brown spots. (Ga., N. J.) irrorata Coquillett. 



ODINIA Desvoidy. 



Bristles of front and mesonotum arising from brown dots, hairs of notum and 

 abdomen arising from smaller brown dots ; front and hind femora 

 with subapical spot ; tibiae with median and apical black rings ; wings 

 reticulate with brown. 4.3 mm. (Ga.) picta Loew. 



Body cinereous, not with setigerous spots ; wings not reticulate 2. 



2. Wings immaculate ; tibiae brown ; sternopleura and a spot above it brown ; 



disk of mesonotum without acrostichal setulae ; abdomen dark brown. 



1.5 mm. (N. H.) immaculata Coquillett. 



Acrostichals present; crossveins at least clouded; tibiae with one or two 

 rings ; pleurae bivittate ; abdomen with paired spots 3. 



3. Front pubescent, reddish above antennae ; acrostichals not seriately arranged, 



but eight to ten on the suture ; both crossveins dark brown ; fifth vein 

 reaches the wing-margin. 4 mm. (Eur.; Wich.) . . .maculata Meigen.
