262 NEW NORTH AMERICAN MELANOPLI (ORTHOPTERA) 



In the females the medio-longitudinal buffy line is broader, and in yellowish- 

 green individuals is often conspicuously margined with brown, which is most 

 decided on the abdomen. In this phase the buffy lateral markings are some- 

 times greatly reduced or wholly obsolete, as is also the dark band of the pro- 

 zonal portion of the lateral lobes. In the paler brown examples the caudal 

 femora have the darker suffusions reduced, the dorsal surface unicolorous; in 

 the yellowish green individuals these suffusions usually disappear, rarely being 

 weakly indicated, the dorsal surface washed with pale brown. No trace of 

 pink pre-genicular annuli is found in the present series. 



The slightly rougher surface and more numerous hairs of the majority of 

 examples of the present race, gives the series less of the smooth and shining 

 facies of the series of pacificus pacificus at hand. 



Specimens Examined: 74; 54 males and 20 females. 



California: Del Monte and San Buenaventura. 



With one exception, these specimens were taken at Del Monte 

 by Hebard on August 20, 1909, and by Rehn and Hebard on 

 September 9 and 10, 1910, and, excluding the type and allotype, 

 are designated as paratypes. The female, recorded by Scudder 

 from San Buenaventura, belongs to the United States National 

 Museum. 



At Del Monte this insect was found scarce on the shore side 

 of the sand dunes, in low scattered grasses and bushes, where a 

 low yellow-flowered " tar-weed" was conspicuous. In this sit- 

 uation more individuals were met with than elsewhere, particu- 

 larly in the sand-loving Composite bush, Chrysoma ericoides 

 (Less.). This race was also present, but scarce, in extensive open 

 areas of short dry grass, where also much of the low yellow-flow- 

 ered " tar-weed" was found. Orthoptera was present in great 

 numbers in these areas, much the most abundant species being 

 Melanoplus microtatus, here described, while Melanoplus devasta- 

 tor Scudder was very numerous and the species here described 

 as Oedaleonotus phryneicus and fratercula were frequently 

 encountered.

The above synonymy is the result of CaudelFs misinterpreta- 

 tion of the original type designation. The type of the genus is 

 not "Caloptenus regalis by original designation," as stated by 

 that author. Scudder gives Aeoloplus regalis as type, without
