I propose the above generic name (derived from xv^V '°^ w ) as a 

 substitute for Lobophora Serv., which is preoccupied in Lepidoptera 

 (Curtis, 1825). Forjicula moiio Fabr. is the type. 



44. Aneistrogaster arthritica. Head, antenna?, thorax, 

 tegmina, wings and legs„covered uniformly and sparsely with short, 

 fine erect hairs. Head and pronotum shining blackish brown, the 

 head with a reddish tinge; antennae very dark chestnut brown, the 

 mouth parts a little lighter ; between the base of the antennas the 

 front has a pair of triangular, rather deep impressions. Pronotum 

 slightly longer than broad, the sides parallel, the posterior angles 

 distinct, the hind border gently convex; there is a distinct median 

 impression half as long as the pronotum, a little in advance of the 

 middle. Tegmina and wings very dark chocolate brown, the latter 

 with a small luteous spot almost concealed by the tegmina; tip of the 

 tegmina squarely docked. Femora dark brown, the rest of the legs 

 dirty luteous, the tarsi slightly paler. Abdomen dark testaceous 

 above, dark castaneous below, darkest at the sides, on both sur- 

 faces profusely and uniformly punctulate; the abdomen broadens in 

 the middle, and besides, the edges of the fourth to the sixth seg- 

 ments expand into lateral depressed teeth of considerable size, curved 

 backward and shaped somewhat as in A. luctuosa Stal. They are 

 first directed outward and a little backward, the hinder two with 

 their anterior edges slightly and roundly excised, but otherwise suf- 

 fering but little diminution in width ; and then they bend suddenly 

 backward and taper to a point, each with a greater or less angulation 

 at the bend, most marked in the hinder two; the outer portion of 

 the upper is nearly twice as long as that of the lower, and hence 

 slenderer, and the middle one stands midway in character between 

 the other two. The forceps have the general shape of those of A. 

 luctuosa', the basal tooth, in the same place, is very slight and blunt, 

 and is followed posteriorly by two or three granulations; the apex, 

 which is finely pointed, is armed a little before the tip by a slightly 

 recurved small triangular lamellate tooth, before which the edge is 

 sparsely, beyond which it is densely pilose. Length of body, 10 mm.; 

 of tegmina and wings, 5 mm.; of hind femora, 3.5 mm.; of front 

 lateral abdominal tooth, 1.5 mm.; of forceps, 4.75 mm. 1 cf. Brazil. 



45. Forficula variana. Head and pronotum luteo-castaneous, 

 the sides of the latter paler. Head smooth, with an oblique, broad,
