extended beyond abdomen, without veins. True wings com- 

 posed of a few simple veins, without a hamus (Fig. 5). Meso- 

 and metasternum fused, disk covered by a smooth subcordate 

 shaped plate, the edge of which is narrowly elevated, linearly 

 impressed down the middle. Odoriferous orifices absent. 

 Legs short; globular coxae widely separated. Femora slightly 

 thickened and flattened, unarmed. Tarsi two-segmented, fur- 

 nished with two widely separated decurved claws and arolia 

 placed close to the claws (see Fig. 4). Abdomen of the male 

 consisting of eight segments besides the genital, the last two 

 and the genital asymmetrical; the eighth segment is slightly 

 transverse and closely fused to the genital apparatus which 

 consists of a flattened elongated sheath, tapering gradually to 

 a more narrow obliquely truncate apex which is turned for- 

 ward along either the right or left side of the body. The fe- 

 male has seven ventral segments, the genital segment covered 

 below by the plate like seventh ; fourth segment posteriorly and 

 the 5th and 6th compressed ; abdomen somewhat asymmetrical 

 posteriorly. Male with seven pairs of spiracles placed ven- 

 trally. 



X. luteolus n. sp. — Pale luteous. Apex of scutellum, apical 

 half of terminal segment of antennae and apex of rostrum in- 

 fuscated. Eyes reddish brown. Form rather narrow oval, 

 much flattened. Head only a little wider than long; porrect; 

 obscurely punctate and faintly wrinkled; suddenly contracted 

 back of eyes which are not in contact with anterior angles of 

 pronotum. Ocelli concolorous, space between these a little 

 over twice the distance to the eyes. Antennas with short basal 

 segment not attaining apex of head, second segment about 

 twice the length of first, third segment a little more slender, 

 subequal to second, fourth narrow spindle-form, nearly as 

 long as third, apical half infuscated and finely pubescent. Ros- 

 trum short, apparently of three flattened segments (base hid- 

 den), infuscated apex reaching only a little beyond anterior 

 margin of prostemum, the latter grooved to receive it. Buc- 

 culae represented by two widely separated ridges. Pronotum 

 slightly transverse, obscurely divided into two lobes, posterior 

 lobe rather closely punctate; anterior and posterior margins 

 concavely arcuated, the former nearly straight in the middle ; 

 transparent lateral margins strongly expanded and slightly re- 

 flexed, edee slightly concave near the middle. Scutellum al- 

 most equilateral, faintly punctate. Semi-transpartent hemi- 

 elvtra with lateral margins widely expanded and slightly 

 reflexed, longer than the abdomen. Clavus parallel sided, 

 irregularly punctate. Commissure about one third the length
