MONUGKAPII OF THE NOKTlI AMERICAN PKOCTOTRYI'ID.E. IHO 



scarcely as hm^ as tlie second, a little liuiu]>ed l>asany; liist and sec- 

 ond seji;incnts striated; rest of the abdoniea suiootb, ])olished, sparsely 

 hairy toward the apex. Wings hyaline, the venation brown, the mar- 

 ginal vein very short, thick, the stigmal vein short, stont at base. 



IlAEiTAT. — Jacksonville, Fla. 



Type in Coll. Ashniead. 



This is the only trne Tltoron in onr fauna, the species described as 

 such, Thoron opacus How,, Ins. Life, Vol. ii, p. 26S, supposed to have 

 been reared from the l^'luted Scale, Icerya purcliasi^ being a $ Teleno- 

 mid and belonging to the genus Phannrus. 



ACOLOIDES Howard. 



IiiK. Life, 11, p. 2li9 (1890). 



(Type A. !<(iitidi.s How.) 



Head transverse, wide, the frons convex; ocelli 3, triangularly ar- 

 ranged, but widely separated, the lateral being- close to the margin of 

 the eye; eyes large, oval, hairy. 



Autennne inserted just above the clypeus; in 9 apparently but 7- 

 jointed, the club being large and inarticulate, the pedicel lengthened, 

 the last three funiclar joints, small, transverse; in $ 12-jointed, fili- 

 form, submouilifi)rm. 



jNIaxillary palpi 4-jointed; labial palpi 2-jointed. 



Mandil)les 3-dentate. 



Thorax oval, the prothorax not visible from above; mesonotum Avith- 

 out furrows; metathorax with the posterior angles subacute. 



Front wings with the marginal vein ininctiform, the ]>ostmarginal 

 not, or scarcely, developed, the stigmal vein long, oblique, thickened at 

 base. 



Abdomen short, oval, the first and second segments short, usually 

 striated, the first much narrower than the metathorax or subpetiolate, 

 the third very large, occupying half, or a little more than half, the whole 

 surface. 



Legs moderate, the tibial spurs very weak, scarcely developed, the 

 tarsi 5-jointed, slender, the l)asal joint of posterior tarsi twice the length 

 of the second. 



This genus maybe identical with AcoJks Fcirster, as s]»ecies occur in 

 it with and without wings, the apterous species fitting exactly into the 

 brief diagnosis of the genus by Fiirster; but as Fcirster's type Aeolus 

 piceiventrisy so far as I know, was never described, and as I have 

 discovered another wingless form closely allied to AcoJoidcs, which is 

 evidently quite distinct, that will also fit into Forster's brief descrip- 

 tion, I have here, in my perplexity, nuide the latter the type of Fors- 

 ter's genus, so as to enable me to retain the well-characterized How- 

 ardian genus. Kirchner's descri])tion of Aeolus liiteus, which might 

 assist me, I have not been able to see.
