ASIIMEAD : CLASSIKICATION OF TIIK CHALCII) FIJKS 261 



in clover seeil. All the other species, however, belonging to this genus, whose i)ara- 

 sitisni is known, destroy coleopterous larva3, and 1 am inclined to think that Ijoth 

 Drs. Howard and Hopkins are wrong, and that BrucJiophdijns fnnrhri.-; is a parasite 

 upon some lirnchvs, or tin; larva of a small I'hynchophorous beetle living in the 

 clover seed. 



The genera ai'e numerous, but it is believed these may be easily recognized by 

 the use of the following table : 



TABLE OF OENEKA. 



1. FemaleK 2 



Males 15 



2. Non-metiillic 3 



Metallic jjreen or blue, eoarsely, iimbilicately punctale. 



Head in front quadricarinate (a carina along the inner orbils and bounding,' the liontal f'nrrow) ; 

 eyes surrounded by a ring of coarse punctures ; antennie 1 l-joinled, sometimes apjiearing 

 only 9-jointed by the union of the club joints ; funicle 6-jointed, the joints long, the first the 

 longest, about two-thirds the length of the .scape ; abdomen conic-ovate, the fifth segment the 

 longest Chryseida Spiiiola (tyjie (' superciliosa Spinola). 



3. Mesonotura distinctly umbilicatcly ininctate 4 



Mesonotum not umbilicately punctate, smooth or nearly, shagreened, or at least ruguloscly punctate. . 12 



4. Fir»t joint of the funicle elongate, as long or nearly as the scape, or at least never less than two-thirds 



the length of the scape .'J 



First joint of the funicle not especially long, never long 'r than half the length of the scape, but 

 usually ranch shorter than that 6 



5. Head with a deep antennal channel, the front ocellus lying in it at ajiex ; antenna' ll-jointed, filiform, 



not or only slightly thickened toward apex. 



Abdomen rarely much longer than the head and thora.x united, strongly compressed, pointed at 

 apex ; .seen from the side, the dorsum is strongly convexly elevated, the fifth segment the 



longest Beplirata Cameron (type B. ruficollis Cam.). 



Abdomen very elongate, narrow, lanceolate, compressed, fully twice as long as the head and 

 thorax united, the segments more nearly equal in length. 



Aximogastra Ashmead, gen. nov. (tyjie ./. Imliise Ashni.). 



(i. Mesonotum willi distinct, conii)lete parapsidal furrows 7 



Mesonotum without parapsidal furrows or the farrows are only indicated anteriorly 14 



7. Head sometimes with a deep frontal channel or antennal furrow, but the front ocellus is never i>laced 



within it, but always above it near the anterior margin of the vertex 8 



Head with a deep frontal channel or antennal furrow, the front ocellus always placed at the apex of 

 this furrow, never above it. 



Scape elongate, more than twice longer than the first joint of the funicle, the funicle joints 

 rather long, the first about twice as long as thick ; abdomen compres.sed, not longer than the 

 head and thorax united, ending in a conical point ; the dorsum, as seen from the side, is 

 highly convexly elevated ; postmarginal vein variable, sometimes shorter than the marginal, 

 but rarely very much longer; hind tibia' with rather .short, stifl!' bristles behind. 



Prodecatoma Ashmead, gen. nov. (type P. ftarescens Ashm.).
