Abdomeu as in Megaspilus, the petiole short, striate, the secoud seg- 

 ment occupying a little more than half the whole surface, the follow- 

 ing segments short. 



Legs pubescent, the posterior tarsi with the first joint as long as all 

 the remaining joints united, the last joint not longer than the second. 



Allied to the wingless forms in Megaspilus^ but with a much laiger 

 head, narrower thorax, and with 4-jointed, not 5-jointed, maxillary 

 palpi. It has also a superficial resemblance to the genus Lagynodes 

 Forster, but the thorax in that genus is not trilobed and the male has 

 an acute spine between the base of the antennji?. 



Two species, E. canadensis and ottawensis, described in Canadian 

 Entomologist, Vol. xx, p. 49, under this genus I find are nothing but 

 wingless species belonging to the genus Megaspilus. The genus as now 

 restricted will contain but a single species, as follows : 



Eumegaspilus erythrothorax sp. nov. 

 (PI. VI, Fig. 6 9.) 



9. Length, 1.9""". Head and abdomen black; face, scape, thorax, 

 and petiole pale rufous or brownish-yellow; legs pallid yellow. Head 

 and thorax closely, minutely punctulate ; petiole striate ; i>edicel and 

 flagellum black, the first flagellar Joint longer than the pedicel. Ab- 

 domen smooth, shining, much longer than the head and thorax united. 



$ . Length, 1.5"^™. Agrees with the 9 , except that the head, the 

 pedicel, and the base of the abdomen as well as the thorax are brown- 

 ish yellow, while the flagellar joints are long and cylindrical, the first 

 being 4 times as long as the pedicel. 



Habitat. — Jacksonville, Fla. 



Types S and 9 in Coll. Ashmead. 



A pretty and easily recognized species, apt to be mistaken for a La- 

 gynodes, but readily distinguished from the characters pointed out in 

 the generic description. 



LAGYNODES Forster. 

 Beitr. 1841, p. 46. 

 Jficrops Hal., Eut. Mag. i (1833). 



(Type L. pallidus Boh.). 



Head deflexed, when viewed from in front, longer than wide, convex, 

 in 9 with an impression above the antennae, in the $ with a spine be- 

 tween the antenna^ ; occiput delicately margined ; ocelli wanting ; eyes 

 very small, rounded. 



Antennae inserted close to the clyx^eus, 11-jointed in both sexes, the 

 scape long, longer than the head, tlie j^edicel more than twice as loug 

 as thick, the flagellum subclavate, the terminal joint not longer than 

 thick, submoniliform. 



Maxillary palpi short, 4-jointed ; labial palpi 2-jointed. 



Mandibles bifid.
