Type in Coll. Ashniead. 



This is the only true Thoron in our fauna, the species desciibe«l as 

 such, Thonm opucus How., Ins. liit'e. Vol. ii, p. -6.S, supposed to have 

 been r«*ared from the Fluted Scale, hrtya piirchasi, being a S Teleno- 

 mid an<l beh)nging t(» the genus Phaniiriis. 



ACOLOIDES Howard. 



IiiH. T.ife, II. !•. 2(>}t (1890). 



(Typi- A. siiitidis How.) 



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

 ranged, but widely separated, the lat<'ral being close to the margin of 

 the eye; eyes huge, oval, hairy. 



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

 jointed, the chib being huge and inarti<ulate, the pedicel lengthened, 

 the last three fuuiclar joints, small, transverse; in S 12-jointed, tili- 

 forni, submoniliform. 



Maxillary palpi i-jointed; labial palpi 2-jointed, 



Mandibles 3-d«'ntate. 



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

 out furrows; metathorax with the posterior angles subacute. 



Front wings with the marginal vein i>unctiform, the i>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 subi)etiolate, 

 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 basal joint of posterior tarsi twice the length 

 of the second. 



This genus maybe identical with jicolim Forster, as sjjecies occur in 

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

 brief diagnosis of tlie genus by Fiirster; but as Forster's type Aeolus 

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

 discovered another wingless form closely allied to Acoloides, which is 

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

 tion, I have here, in my perj^lexity, made the latter the type of Fors- 

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

 ardian genus. Kircliner's description of Aeolus hdena, which might 

 assist me, I have not been able to see.
