S£ VISION OF THE MKLASOPLI—SCUDDKB. II 



A-. Lateral margins of snb','enital plate of male Hiwhleuly ainpliatf to a consul* ruble 

 de/^'ree at thi- base; or if not to a considerable degree, then the entire margin rather 

 strongly convex or sinuate. . 



ft'. Snbgenital plate of male furnished with a distinct subapical tubercle (i. e., one 

 in which the afl* al margin does n»)t jiass thr(»ugh and form a ]»art of the summit 

 of tlif tubercle, but where it is distinctly separate<l from that summit;, but not 

 otherwise tumescent.' 

 ( '. Median carina of pron<»tum well developed and equally develope<l through- 

 out, accompanied on the front <»f the pro/.oua by distinct lateral carinae; pro 

 sternal spine sha'-ply acuminafc: tubercle of snbgenital idate directed wholly 

 backward, occtipving tlie middle of the terminal portiitu of the plate; furcula 



diptinctly developed 16. Eotettix ip.oS). 



(■■. Median carina of pronotum feebly developed and genc-ally much more feebly 

 on the prozona than on the metazona, accompanied by no late al carinae what- 

 ever; prosternal spine blnntlv acuminate; tubercle of snbgenital plate directed 

 upward or upward and backwaril, occu]tying the upper extremity of the ter- 

 minal portion of the plate. 

 (V. Jiody relatively slender and compressed, not mn<h enlarged at the meta- 

 thorax, particularly in the male: disk of the pronotum tectiforni,^ tlie pro/ona 

 not distinguished from tlio metazona either by its jdanc or by any lack of a 

 me<lian carina, whidi latter 's generally marked in color; pronotum fully half 

 as long again as broad ; hind femora long and slender; apical tubercle of male 

 abdomen pniminent; fnrcula present as distinctly i)rqjecting lobes; terminal 

 segments of female abdomen not abbreviated, the ovipositor fully exserted. 



17. Hesperotei t ix iii.^o). 

 (f ^. Body relatively short and stout, considerably enlarge«l at the njetathorax 

 even in th< male; disk of pronotum gently convex transversely, the prozona 

 slightly and independently tumid with no median carina, thus distinguishing 

 it from the metazona; ' hind femora relatively short and stout; apical tubercle 

 of male abdomen not very prominent; furcula scarcely or not apparent ; termi- 

 nal segments of female abdomen abbreviated, the ovipositor only partially 



exserted 18. Jeoloplua (p. (i8). 



h-. Snbgenital plate of male with no distinct subapical tubercle, but often apically 

 prolonged or tumescent.* 



cK Meso- and metastethia together, in both sexes, no longer or scarcely longer 

 than broad; metastethium narrowing but little posteriorly, so that the portion 

 behind the metasternal lobes is but little narrower than the rest, rarely (iu the 

 male) less than three-fonrths its width; cerci of male very simple, snbconical, 



straight; ovipositor half concealed 19. Braiijuotes (p. 80). 



C-. Meso- and metastethia together, at least in the male and nearly always in 

 both sexes, distinctly longer than the width of the raetastethium ; the latter 

 rapidly narrowing posteriorly, so that the portion behind tbe metasternal lobes 

 is not, or is hardly more than, one-half the greatest width of the metastethium; 

 cerci of male variable; ovipositor generally fully exserted. 

 rf'. Interspace between mesosternal lobes of male distinctly transverse,^ as 



'• See note under alternate category. 



'This feature is not so apparent in the first three species of Hesperotettix as in the 

 others. 



3 This feature is less marked in Ae. tenuipennis and Ae. elegans than in the others. 



^There is a minute subapical tubercle in some species of the flabellifer series of 

 Jlelanoplns, but in these the male cerci are exceptionally broad and tlabellate, while 

 in the species of the alternate category (J- ft') the cerci are very slender and tapering. 



"■In numy cases the interspace is truncato-cuneiform or broadly clepaydral, in 

 wliich cases the breadth is to be measured in the middle. In a single species of 

 Podisma, P. dairisama, tbe interspace is slightly longitudinal.
