162 NEW NORTH AMERICAN MELANOPLI (ORTHOPTERA) 



The similarity in general type of color pattern, particularly 

 that of the tegmina, shows the affinity of these species and dis- 

 tinguishes them from the other species of the Pratensis Group. 



Type. — cf ; Ocala, Marion County, Florida. September 19, 

 1917. (Rehn.) [Hebard Collection, Type No. 482.] 



Agrees with the type of gemmicula except in the following features. Size 

 (averaging in series) larger; form slender, slightly more robust than in gemmi- 

 cula. Dark bar of prozonal portion of lateral lobes of pronotum narrow and 

 solid in coloration, the ventral border of this bar white (as broad in the type, 

 twice as broad or slightly more than twice as broad as the bar in the other 

 specimens). Tegmina greatly reduced, appreciably shorter than pronotum 

 (varying in series to very slightly longer than pronotum), slightly overlapping; 

 form broad ovate, the dorsal field being distinctly defined from the lateral 

 field. Tegmina distinctively colored, as in gemmicula) dorsal and lateral fields 

 green except for a rather broad longitudinal humeral band of pink, the dorsal 

 portion of this band in the lateral field darkened. Genitalia as in gemmicula, 

 except that the cerci in the narrow distal portion have their margins feebly 

 convex. 20 Caudal femora green, the pregenicular pinkish annulus broad and 

 distinct, no transverse bands occur on dorsal surface as in gemmicula, or pink 

 suffusion on external face and external margin of dorsal surface as in H. 

 brevipennis (Thomas) . 



Allotype. — 9 ; taken in coitu with type. [Hebard Collection.] 



Agrees w r ith type except in the following features. Size much larger, form 

 more robust. Diagnostic features of coloration as given for the male, except 

 that the medio-longitudinal dorsal stripe of the pronotum is decidedly broader, 

 pale, with very dark margins and is continued on the abdomen to near its 

 apex. Ovipositor valves normal for the genus.

The coloration and color pattern of this insect shows no impor- 

 tant differences from that of gemmicula. It is possible that this 

 insect may eventually prove to be a geographic race of that 



20 In this genus, showing so little differentiation in the simple type of cerci* 

 we believe that frequent slight individual variation will be found to occur and 

 that such difference as here given may prove to be of very little diagnostic 

 value.
