i. BARYTETTIX CRASSUS, new species. 

 (Plate II, fig. 10.) 



Luteo-testaceous, probably flavescent in life, marked with fuscous 

 and black. Head subluteous, a little infuscated on vertex and with 

 a fuscous band behind the eye distinct only at its upper margin; bor- 

 ders of fastigium and frontal costa punctate; other parts of face very 

 obscurely and sparsely punctate; frontal costa sulcate throughout; 

 antennae luteo-testaceous, becoming infuscated on the apical half. 

 Prozona luteo testaceous above, luteous on the lower half of the lateral 

 lobes, their upper half occupied by a broad piceous patch which nar- 

 rows anteriorly by the excision of its lower margin; inetazoiia fusco- 

 testaceous; epimera black. Tegrnina blackish fuscous with dull luteous 

 veins. Fore and middle legs luteo-testaceous, the apical half of the 

 claws black, the arolia much more than half as long as the last tarsal 

 joint, narrowly edged with black (hind legs wanting). Abdomen with 

 a narrow laterodorsal dark fuscous stripe on some of the basal seg- 

 ments, and most of the segments dorsally margined posteriorly with 

 testaceous. Supraanal plate of male triangular with sinuous sides, 

 either longitudinal half broadly and deeply sulcate, the rising margins 

 between them inclosing a deep and rather narrow median sulcus, con- 

 stricted at the middle; furcula consisting of a pair of approximate, 

 very small, rounded lobes, scarcely projecting; cerci very broad and 

 compressed, a little narrowed before the middle, the basal portion a 

 little bullate, the apical produced by its inferior extension, the apex 

 acutely angulate and curved downward, the whole very feebly incurved ; 

 upper margin of the subgenital plate straight throughout, well rounded 

 apically, the tubercle very coarse and very blunt, nearly doubling the 

 length of the plate. 



Length of body, male, 21.75 mm.; antennae, 11 mm.; tegmina, 4 mm.

2. BARYTETTIX PENINSULAE, new species. 



Light testaceous with a luteous tinge, marked with black. Head 

 testaceous with a faint ferruginous tinge, marked above with a median, 

 more or less broken, black stripe which follows the sulcus of the fastig- 

 ium and broadens considerably behind; also with a very broad black 

 band behind the eyes; whole face and lower portion of the geuae dis- 

 tinctly but sparsely punctate, the frontal costa feebly convex except 

 for a slight depression below the ocellus; antennae light ferruginous 

 on basal, ferruginous on apical half. Metazona testaceous with no 

 luteous but a feeble olivaceous tinge, the prozona luteo-testaceous, 

 marked on disk with a couple of narrow, parallel, subdorsal black lines 

 on its posterior half, which cross also the metazona, but are there 

 evanescent and slightly divergent; lateral lobes of the prozona marked
