mesad on the costal margin. Exposed portion of the wings colored 

 similarly to the distal portion of the tegmina. Abdomen with a 

 broad, medio-longitudinal, dorsal bar of shining black, which includes 

 the whole of the supra-anal plate; laterad of this bar the abdomen 

 bears a pair of deep-chrome areas. Femoral and tibial spines tipped 

 with black. Ovipositor teeth fuscous tipped. 



Length of body (exclusive of ovipositor), 18.2 mm.; length of pro- 

 notum, 3.9; greatest (caudal) width of pronotal disk, 3.1; length of 

 tegmen, 24.2; greatest width of tegmen, 4.1, length of caudal femur, 

 19.1; length of ovipositor, 5. 



In addition to the type we have before us four paratypic females 

 bearing the same data as the type, except that two were taken in 

 April instead of March. The paratypes fully agree with the type 

 in all essential features. In coloration they have some variation in 

 the general tone, but the relative values remain the same. In one 

 individual, which is not the palest of the lot, the facial markings are 

 subobsolete. 



Ligocatinus minutus new species (Plate X, flgs. 19 and 20.) 



A strikingly small member of the olivaceiis-longicercatus-sordidus 

 group of the genus, which in size is hardly more than two-thirds 

 the bulk of the smallest of the previously known species. The 

 genitalia are nearest in type to those of longicercatus, but the sub- 

 genital plate is hardly emarginate, while the caudal femora are 

 unarmed beneath distad and the size, as already mentioned, is very 

 much less. From olivaceus the species differs chiefly, aside from the 

 smaller size, in the unspined ventral margins of the caudal femora, 

 the form of the cerci and in the short styles of the subgenital plate. 

 'The species sordidus is known only from the female sex, but the size 

 is quite different, the caudal femora are spined ventrad and the 

 .angle of the caudal margin of the lateral lobes of the pronotum is 

 more decided and less rounded. 



Type. — cf ; Goyaz, State of Goyaz, Brazil. [Hebard Collection, 

 Type no. 416.] 



Size quite small: form as usual in the genus. Occiput gently 

 rounded, regularly but strongly rounded to the fastigium, least 

 width between the eyes slightly less than the depth of one of the 

 eyes; fastigium compressed, weakly strumose proximad, distal por- 

 tion faintly bullions, sulcate dorsad, when seen from the lateral 

 aspect rounded, largely in contact with the fastigium of the face; 

 eyes moderately prominent, subreniform- ovate in basal outline, in 

 <lepth subequal to the infra-ocular portion of the genac; antennae
