var. Hylechihrus rubi pustulatus Saunders, 1872. 

 Hylechthrus rubi Saunders, 1852, 1872. — Pierce, 1908. 



Host. — Prosopis rubicola Saunders; Epirus, June (fig. 3, nos. 7, 8; 

 pi. 5, figs. 1,2). 



The original description by Saunders is essentially as follows: 



Male. — Black, legs luteous, wings milky, veins piceous. Length 

 ^-f lines; wing expanse almost 1J lines. Head large, transverse. 

 Eyes very large. Thorax anteriorly constricted; disk gibbous, 

 subequal to breadth of head; praescutum very large, elongate- 

 triangular, with anterior margin sinuate, sides straight, with posterior 

 angle subacute, porrect. Elytra small, apically strongly dilated 

 clavate, subconcave. Wings thickened on costal margin to middle, 

 subcosta abbreviated, joined to costa; radius parallel with subcosta, 

 becoming evanescent beyond middle of wings; medius arising from 

 radius at base, straight, deflexed from radius; between radius and 

 medius lie a detached branch of each, the first very strong at base; 

 cubitus not basally attached, slender, attaining external margin; first 

 two anal veins subapproximate, near internal margin, strong at base, 

 third anal almost obliterated. Abdomen strongly constricted. Legs 

 of moderate length, posterior tibia? dilated, compressed. 



Female. — Larviform; cephalothorax flattened, above subconvex, 

 below subconcave, pale, with darker marginal line; with a vitta on 

 each side, two small transverse spots near base, and posterior angles 

 brown. 



o Male.— Niger, gibbosus; pedibus luteis; alis lacteis; venis saturate piceis. 



Long. corp. ^-f lin. Expans. alar, fere 1£ lin. 



(The remainder is from the original generic description.) 



Caput magnum, transversum. Oculi ingentes. Thorax antice constrictus, disco 

 gibboso capiti latitudine subsequali; scutello maximo; elongato-triangulari; margine 

 antico sinuato, lateribus rectis, angulo postico subacuto porrecto. Pseudelytra 

 parva, apice valde dilatato crassiori, subconcavo. Alae, costae dimidio basali in- 

 spissato, seu potius vena subcostali, abbreviate cum costa quasi conjuncta, prima 

 discoidali, prope basin furcata, rama antico ejius cum costa parallelo, ultra medium 

 alae evanescente ramo postico, recto, deflexo; prope apicem alae incrassatio exstat, 

 cujus basis, venaque duplex tenuissima de margine externo sinuate producta, intra 

 furcam, retro extendunt: venis reliquis rectis, deflexis; quarum una gracilis, margini 

 externo attingens; duae subapproximatae, margini interno propiores, basi robustiores; 

 altera (?) analis fere obliterata. Abdomen valde constrictum. Pedes longitudine 

 mediocres, posteriorum tibiis dilatatis, compressis, genubus constrictis, tarsorum 

 articulis quatuor, apicali integro. 



Female.— Vermiformis; cephalothoracem complanatum, supra subconvexum, infra 

 subconcavum, e dorso apis educantis tantum modo protrudens; vaginae aditu, olim 

 clauso, post coitum, sat ample patenti. Nuper declarata, cephalothorace pallido, 

 lineola marginali tenuissima nigricanti; vitta utrinque, maculis binis parvis trans- 

 versis prope basin, angulisque posticis, brunneis; parturientes autem disco con- 

 vexiori, fere omnimo flavescenti, vitta media longitudinali dilutiori (Saunders, 1850).
