DIPONTHUS PARAGUAYENSIS, new species. 



About the size and form of I), schuh! Brunei', but differing from 

 that .s})ecies in having the veins of tegmina, the legs and pronotum, 

 together with body testaceous. The darker portions of head, prono- 

 tum, and legs in this form are dark olive instead of deep black, as in 

 the species to which it has been compared. The present species also 

 lacks the red markings of the head and knees of that insect. 



Head rather small, the fastigium depressed, the vertex between the 

 eyes a little wider than the broadest part of the frontal costa, the latter 

 of nearly equal width throughout (female) or with the sides decidedly 

 convergent below (male), flat abov^e, sulcate at and below the ocellus. 

 Pronotum short, rather coarsely and profusely punctate above and on 

 sides of hind lobe, the latter a very little longer than the anterior one; 

 hind margin very broadly angulate. Tegmina and wings reaching 

 beyond the abdomen in both sexes. Hind femora as long as the 

 abdomen. 



The median line of head and pronotum above fades posteriorly, 

 while the oblique lines on the sides of latter are bordered below by a 

 slight infuscation. The cells of the tegmina are fuliginous, with the 

 veins and cross-veins and the edgings of the membrane to a consider- 

 able extent testaceous. This gives to these members the appearance 

 of being testaceous and rather evenl}^ conspersed with dull black. The 

 wings deep rose, the apices pale, with dusky veins. Hind femora 

 crossed above by two dark bands; the outer and inner faces have in 

 addition a basal blotch and the upper half of the genpe dark — the latter 

 black; hind tibiae olivaceous or testaceous, the apex and hind tarsi infus- 

 cated. Antenna? dark colored annulate with paler. 



Length of body, male 25, female 32; of pronotum, male 4.4, female 

 5.5; of tegmina, male 22, female 28; of hind femora, male 12.5, female 

 16 mm. 



Ti/jje.—C&t No. 9724, U.S.N.M. 



JlahiUd. — Two specimens, male and female, from Sapucay, Para- 

 guay (coll. L. Bruner); Sapucay, Paraguay, several specimens of both 

 sexes taken by W. T. Foster (coll. U. S. Nat. Mus.). 



It is possible that both D. dlspar and I), festivus of Gerstaecker 

 will also be found to occur in Paraguayan territory. One of the 

 species of this genus, D. communis Bruner, is figured herewith on 

 Plate XXXVn, fig. 6. 



LEPTYSMA Stal. 



An examination of all the American locusts that fall into the genus 

 Leptymna would indicate that it contains a much larger number of 

 species than generally has been conceded; and, as is recognized at 

 present, it is composed of two series of species, namely, the one more
