According to Mr. Howard this insect avus reared by Mr. 1>. W. Co- 

 quillett, July 27, 1887, from the adult female of Iccrya, jyurchasi. I am 

 not willing to acce^Jt this statement as accurate, the species being an 

 egg-parasite. As with the European Telenomus coccidivorus, additional 

 evidence is needed to substantiate its divergent habit. 



TELENOMUS Hcaliday. 

 Ent. Mag. i, p. 271 (1833). 

 Syn. (?) Hemisiiis Weaiwood, Phil. Mug., ii, p. 44.5 (1832). 

 (Type T. hrachialiH Hal.) 



Head large, transverse, usually very wide, very rarely quadrate, the 

 occiput concave, not margined. Ocelli 3, triangularly arranged and 

 widely separated, lateral contiguous to the margin of the eye. Eyes 

 oval, often pubescent. 



Antenna*- inserted close to the clypcus, in 9 11-Jointed, clavate, the 

 club 4- or 5 jointed, the jiedicel usually larger than the tirst funicle 

 joint, the first funicle joint longer than wide, the last two funicle joints 

 minute, transverse; in S filiform, pubescent, moniliform or submonili- 

 form, the joints after the fifth rarely elougate-cylindric. 



Maxillary palpi 2-jointed. 



Thorax ovoid, the mesonotum wider than long, without furrows; the 

 metathorax short, rounded, unarmed. 



Front wings pubescent, ciliated, the submargiual vein joining the 

 marginal at about ^ the length of the wing, the marginal vein linear, 

 rarely iiunctiform, and usually shorter than the stigmal, the latter ob- 

 lique and rather long, the post-marginal vein long. 



Abdomen subsessile, broadly oval, depressed, not or rarely longer 

 than the thorax, the apex usually truncate, the first segment wider than 

 long, the second always the largest and longest segment, although 

 often wider than long; the following segments all short. 



Legs moderate, the femora subclavate, the tibial spurs weak, the 

 tarsi o-jointed, not as long as the tibite. 



A well known and widely diKstributed genus found in all parts of the 

 world. Haliday and Walker have described in it species that should 

 now be relegated to rhannrus. The species are numerous and proba- 

 bly susceptible of a still further generic subdivision. 



The description of West wood's genus Hemisim^ with one species, 

 minutns, appeared in the Phil. Mag, Vol. ii, p. 445, 1832, and conse- 

 quently antedates that of Haliday (which did not appear until 1833) 

 just one year. From Westwood's brief description I am unable to sepa- 

 rate it from TelenomuSy and if Telenomus is not again subdivided it 

 must replace that now well-known genus. 



Species of the genus Telenomus, according to Dr. Gustav Mayr, have 

 been reared in Europe from the following insect eggs: 



Lepidoptera 13 species. 



Hemiptera 3 species. 



Diptera 1 species.
