72 THE CANADIAN ENTOMOLOGIST. 



of the golden rods (Solidago rigida) at West Point, Nebraska, during 

 the latter part of the month of September, 1886. Male not known to me. 



The species is evidently quite local in its distribution ; and perhaps 

 also quite rare. A better knowledge of the habits of our North Ameri- 

 can Orthoptera may also aid in finding them. ' 



There is a single female specimen of a closely allied, though distinct 

 species, in my collection, which was taken in the District of Columbia. 

 This latter form is also undescribed, and can be known temporarily as 

 Orchelimufn minor, from its rather small size and short wings. It is 

 slenderer and in every way smaller than 0. gladiator. In colour it is 

 rather less green than usual, and has the brown markings very decided. 

 Its ovipositor which resembles that of gladiator is also brown instead of 

 green. 



I have still other undescribed Orchelimtims in my cabinet, but must 

 postpone their description for a future paper. If others who have speci- 

 mens of these insects in their collections which do not appear to have 

 been described, and they do not care to work them over themselves, it 

 would be deemed a favour if they were sent to the writer, who would then 

 endeavour to prepare a paper on the tv/o genera which would include all 

 of the known as well as any new forms that might still remain undescribed. 



In addition to several described species of Co/ioccphalus, we have 

 here in Nebraska a heavier bodied and shorter winged form than the C. 

 ensiger Harris, which appears to be new. 



ConocepJialiis nebrascensis, n sp. — Most closely related to C. ensiger. 

 Cone of the vertex entirely black beneath ; ovipositor long and lance- 

 like. 



Cone of the vertex rather slender, its sides parallel from a little in 

 advance of the eyes to its middle, from which point it tapers to the 

 rounded apex ; the basal tooth quite prominent. Eyes large and promi- 

 nent, usually dark coloured. Pronotum large and broad, the shoulders 

 well defined, the posterior extremity broadly rounded, the deflected lobes 

 or " side laps " spreading below ; the entire surface rather shallowly punc- 

 tate, glabrous. Tegmina coriaceous, with large coarse tympanum in the 

 male — very similar to that of C. crepitans and C. robustus Scudd. 

 Posterior femora moderately slender, short, and with both the inner and 

 outer lower carina? provided with spines. Anal cerci stout, with strong 

 internal hooks; sub-genital plate quite large and broad; the projecting 

 " digits " widely separated and small. Ovipositor long and slender,
