PARACORNOPS Giglio-Tos. 



This genus is based on the insect which has been determined by 

 Giglio-Tos as De Geer's Acridiuru longipenne which, according to that 

 author, came from Surinam (Dutch Guiana). Without having material 

 from that country for comparison, it would be a difficult matter to defi- 

 nitely recognize the insect to which De (leer gave the name long'qienne. 



Be this as it may, Stal thought that he recognized in an insect from 

 Brazil De Geer's species, and placed it in Scudder's genus Cornops." 

 Later Giglio-Tos'' recognized the generic distinctness of Cornopshivit- 

 tatuin. Scudder and the Acridium longlpenne De Geer. He therefore 

 suggested the name Paracornops for the De Geerian species. 



By a rather careful study of the description and figure it Avould 

 appear that if De Geer's insect really occurs in the region under con- 

 sideration in the present paper, and is contained in the material at 

 hand, we will have to ta))ulate the species as follows: 



TABLE FOR DETERMINATION OF SPECIES. 



a. Upper valves of ovipositor provided externally with 4 or 5 large teeth. General 

 color of insect greenish ferruginous above, testaceous on sides and below. More 

 finely and closely punctate. 

 6. Smaller (male 19, female 25 mm.). The lower lateral edges of pronotum some- 

 what sinuate longipenne ( De Geer) 



bh. Larger (male — ?, female 33) . The lower edges of pronotum not sinuous. 



jxtrnguayense, new species 



cui. Upper valves of the ovipositor provided externally with 6 or 7 small teeth. 



(leneral color of insect grass-green or olivaceous above, greenish yellow below. 



More coarsely and sparsely punctate. 



6. Punctuation of pronotum and pleura quite regularly distributed, leaving no 



decided glabrous patches. Hind femora much surpassing the abdomen. 



uqaaticuin, new species 



bb. Punctuation of pronotum and pleura somewhat irregularly distributed, leaving 



glabrous patches on sides of pronotum and pleura. Hind femora only a 



trifle surpassing the abdomen porition, new species 



PARACORNOPS LONGIPENNE (De Geer).? 



This insect is included as a Paraguaj'^an species on the authority of 

 Giglio-Tos, who gives its habitat as the province of San Pedro. There 

 are several specimens, male and female, in the writer's collection 

 which come from Sao Paulo, Brazil, a short distance to the eastward, 

 which have been determined as this species. They are darker colored 

 than De Geer's description would indicate, but for size and markings 

 would be just about right. 



Length of l)ody, male, 10, female, 25; of pronotum, male, 4, female, 

 5; of tegmina, male, 19, female, 23.5; of hind femora, male, 12, female, 

 15; of antennae, male, 7.5, female, 6.5 mm. 



No synonomy is given for this insect at present, but will be later in 

 a paper under contemplation.
