SUBFAMILY IV. CONOCEPHALINJE. 54.1 



grassy bogs inland at the head of sluggish streams. Occasionally 

 it spreads to the adjoining dry land, specimens having been taken 

 in goose-grass, Elcusinc indica L., crab-grass, foxtail-grass and 

 Andropogon." 



246. ORCHEOMUM ERYTIIROCEPHALUM Davis, 1905, 288. Red-headed Mead- 

 ow Grasshopper. 



Size medium to large for the genus, form robust. Green or greenish- 

 yellow, hind knees and tarsi fuscous; occiput and prozona with a broad 

 median dark brown dorsal stripe, in the larger specimens this often faint 

 or wanting; entire head and face usually blood-red in life, fading to red- 

 dish-brown in drying; pronotum short, smooth, its posterior lobe short, 

 with hind margin broadly rounded; lower margin of lateral lobes with 

 hind angle narrowly rounded, hind margin with convey callosity broad; 

 humeral sinus broad, very shallow. Tegmina surpassing tips of hind fe- 

 mora 2 4 mm., exceeded by wings the same distance. Hind femora usu- 

 ally armed beneath on each carina with one to six spines. Cerci as de- 

 scribed in key and shown in Fig. 179, the tooth suddenly constricted into 

 a slender, sharp bent spine. Ovipositor as shown in Fig. ISO, &, slightly 

 less than half the length of hind femora. Length of body, $ and 9 , 20 

 27, of pronotum, $, 5.58, 9, 67.5; of tegmina, $, 2233, 9, 2337; of 

 hind femora, , 1723, 9 1822; of ovipositor, 910. 



This meadow grasshopper, as described above, is the species 

 which R. & H. (1915a, 34) call 0. glaJx-rriiniini (Burm.). Tin- 

 original description (1S38, 707) of that species is very brief and 

 not distinctive. It is as follows : "Yerticis et pronoti medio 

 fulvo, nigro-marginato ; elytris ab alis dimidia linea snperatis. 

 Long, corp., 11"'." Burmeister knew bnt two species from the 

 United States, and this short description was sufficient for him 

 to distinguish these, but of the 18 or more species now known it 

 is impossible to say just which one he had at hand. R. & H. by 

 "tracing the movements of Zimmerman, who collected the ma- 

 terial on which Burmeister founded his glabcrriiiiiini," have con- 

 cluded that his type came from Georgtown, S. Car., and have 

 picked out the species found in that general region which, in their 

 opinion, fits most closely the above brief description and have 

 called it glaberrimum. In doing this they made the cri/throcejt- 

 iKilmii of Davis a synonym. They have also placed as a synonym 

 of their glabcrriniiiiii Burin, the 0. cnticnlare Serv. (1839, 523), a 

 species of which Serville said: "J'ignore sa patrie." 



As stated in the introduction to this work, p. 7, in cases 

 of this kind, where the insect cannot be definitely fixed as the 

 one so briefly described by a foreign author, it is better to disre- 

 gard his name and to adopt a later one of undoubted status. 1 '' 7
