This species has been recorded from a long Hst of lepidopterous, 

 hymenopteroiis, and dipterous hosts and is known to develop as both 

 a primary and a secondary parasite. It was originally described 

 from Europe, w^here it is widely distributed, and has also been reported 

 from Japan. Voluntarily introduced into America to combat the 

 gipsy and browntail moths, it is said now to be distributed over the 

 entire region infested by these pests. A detailed account of the life 

 history, distribution, and hosts of aereus is given by Muesebeck ' and 

 may be consulted for more complete information. 



3. MONODONTOMERUS CUBENSIS, new species 



The apex of the scutellum in this species is less strongly sculptured 

 and more shining than in an}^ of the other species placed in the key 

 under the group having it sculptured. In some specimens this sculp- 

 ture is, in fact, so weak that it may easily be overlooked unless a 

 isdrly high magnification is used. The shorter ovipositor, together 

 with the bright testaceous color of the anterior and middle legs, 

 exclusive of their coxae, distinguishes the species from mexicanus, 

 which it most closety resembles. 



Female. — Length 3.3 mm.; ovipositor 0.8 mm. Head and dorsum 

 of thorax nearly uniformly dull brassy green; propodeum, pleura, 

 coxae, and all femora blackish green, less strongly tinged with brassy 

 than the dorsum; anterior and middle legs, except their coxae, pos- 

 terior trochanters, extreme apices of posterior femora, posterior tibiae 

 and tarsi, and the antenna! scape bright testaceous; all tarsi a little 

 paler than tibiae; antennal pedicel brownish testaceous; flagellum 

 black; wings hyaline, with a spot embracing the stigmal vein and 

 extending approximately one-third of the way across the wing very 

 dark fuscous; tcgulae fusco testaceous; abdomen blackish with metallic 

 reflections. 



Head uniformly shagreened and rather densely hairy; 63^08 with 

 sparse, short pile; ocellocular line equal to or very slightly shorter 

 than diameter of a lateral ocellus; temples nearly transverse to longi- 

 tudinal axis of body; malar space equal to about one-third the eye 

 height; malar furrow complete and strong; anterior margin of face 

 nearly straight, the clypeai margin very slightly protruded. Anten- 

 na! scape cylindrical, not quite attaining front ocellus; pedicel very 

 nearly as broad as long; ring joint strongly transverse; funicle thicker 

 than pedicel and of the same thickness throughout its length; first 

 funicle joint a little longer than broad, all the others quadrate or 

 nearly so; club ovate, slightly broader than funicle, and a little longer 

 than two preceding joints combined. Mandible with three very short, 

 subequal teeth.
