The Thirty-two Spotted Grasshopper. 



[Genus PHANEROPTERA (Aud. Serv.). (Sub-kingd. Articulata. Class Insecta. 

 Order Orthoptera. Section Saltatoria. Family Gryllidse.) 



Gen. Char. — Head small, narrow, oval, vertical ; antenna? close together at base, longer 

 than the body, setaceous, multiarticular^ ; 1st joint large, elongate; 2nd spheroidal; capillary 

 from the 3rd joint. Eyes small, prominent ; no ocelli ; labrum small, rounded ; mandible 

 moderate, slender; maxillary palpi with last joint twice as long as that of labial palpi, both 

 truncated at tip. Legs long, slender ; posterior femora very long, smooth ; tibia? long ; spines 

 of legs few and small ; anterior tibia? with a basal swelling, having a distinct oval cavity ; tarsi 

 4-jointed, 3rd joint narrow, bilobed. Elytra long, narrow, extending beyond the abdomen 

 when at rest, and having large stridulating organ on inner base in the males ; wings large, 

 extending beyond the elytra. Prothorax short, flat or concave above, posterior edge sometimes 

 raised ; presternum smooth ; mesosternum and metasternum concave, with raised lateral 

 borders. Abdomen narrow ; subanal plate of male bifurcate at tip, the two branches extending 

 beyond the abdomen ; two upper appendages long, setaceous, pubescent, those of the male 

 a little arched upwards and much larger than in the female ; ovipositor very short, arched 

 upwards from base, rouned at tip ; valves flat, smooth above. 



(Sub-genus Ephippitytha) (Serville) — Prothorax saddle-shaped, hollowed transversely, 

 narrow and convex in front above, abruptly widening into a rounded dilated portion raised behind. 

 Thighs and legs strongly spinous. Front with one tubercle.] 



Description. — Female : Body yellow ochre, glossy ; top of head blackish- 

 brown ; a rusty yellow spot under each eye. Frontal tubercle small, conical ; point 

 not reaching- front of basal joint of antennae. Prothorax saddle-shaped, hollowed 

 on the deflected sides ; upper surface contracted in front, widening- abruptly behind ; 

 obliquely inclined upwards from the anterior to the posterior margin, with a median, 

 triangular, reddish-brown spot ; sides green, bent down, long, rounded ; posterior 

 portion brown, elevated, flat, rounded at the base of the elytra; sides of this plate 

 with a black, polished, semilunate spot, wider in front. Elytra rather opaque, ex- 

 tending nearly an inch beyond the end of the abdomen, dull yellowish-green ; 

 anterior border wide, sinuous, narrowed towards the tip, which is rounded and of a 

 duller color; the reticulate neuration of this margin coarse, irregular; each elytron 

 with 8 to 10 oblong black spots in a longitudinal line on a paler streak, touching the 

 posterior or inner margin of great marginal vein ; 8 to 13 other similar spots form- 

 ing an irregularly placed row on the inner margin of the elytra. Stridulating organ 

 opaque, with reticulate neuration like that of anterior margin ; hind wings trans- 

 parent, with slightly-opaque green tips. Legs green, with transverse brown spots ; 

 hind thighs with 2 rows of moderate spines below ; hind tarsi with 2 rows of 

 moderately large spines above, 2 anterior pairs of legs, nearly smooth ; 2 hinder 

 joints of sternum green, with the deflected edges yellow. Base of anterior tibia? 

 swollen, with a large, oval, talc-like, glossy plate covering the cavity on both the 

 outer and inner sides. Antennae slender, setaceous, of very numerous, indistinct, 

 cylindrical joints beyond the basal and 2nd joints, which are enlarged, the basal joint 

 slightly exceeding the frontal tubercle in length. Length of body, 1 in. 4 lines ; 

 length of each of the tegmina, 2 ins. 1 line; greatest width of same, 5 lines ; length of
