incurved, the tip bluntly angulate below, tbe whole fully twice as long 

 as basal breadth; subgenital plate long and narrow, narrowest in the 

 middle, the lateral margins ampliate and well rounded at the base, and 

 as a whole sinuate, rising again at the apex, the apical margin as seen 

 from behind broadly angulate, entire. 



Length of body, male, 16 mm., female, 26 mm. ; antennae, male, 7 mm., 

 female, 8 mm. ; tegmina, male, 3 mm., female, 4.75 mm. ; hind femora, 

 male, 10 mm., female, 15.5 mm. 



Three males, 5 females. Monterey County, California, M. E. Curran 

 (L. Bruner); Los Angeles, Calfornia, Coquillett (same); Los Angeles 

 County, California, Koebele (same); San Bernardino County, Califor 

 nia, August 18 (U.S.N.M. Eiley collection); Kern County, Cali- 

 fornia (U.S.KM.). 



As there is considerable variation in the slenderness of the tegmina, 

 the name given by McNeill is not closely applicable. 



It is possible that the single female from Monterey County does not 

 belong here, as it varies from the others, as indicated in part by the 

 description, in having a subbasal annulus on the hind tibiae, and has 

 considerably broader tegmina than any of the others and hardly any 

 trace of markings on the hind femora. If it is distinct, it indicates an 

 undescribed species of this same series very closely allied to the present. 



63. MELANOPLUS MISSIONUM, new species. 

 (Plate XVI, fig. 8.) 



Of average size, dark, ferrugineo-fuscous. Head feebly prominent, at 

 least in the male, testaceous, heavily punctate with fuscous, above 

 blackish fuscous, enlivened by a testaceous stripe following the margin 

 of the eye posteriorly, and separating the fuscous summit from the broad 

 piceous postocular band ; vertex gently tumid, distinctly elevated above 

 the level of the pronotum, the interspace between the eyes nearly 

 (male) or fully (female) half as broad again as the first antennal joint; 

 fastigium somewhat decliveut, throughout distinctly (male) or scarcely 

 (female) sulcate; frontal costa rather prominent, almost reaching the 

 clypeus, equal or, in the male, sometimes feebly narrowed above, slightly 

 broader than the interspace between the eyes, feebly sulcate at, and in 

 the male below, the ocellus, rather closely punctate throughout like the 

 rest of the face; eyes moderately large, slightly prominent, much longer 

 than the infraocular portion of the^genae; antennae luteo testaceous, 

 about three-fourths (male) or more than three-fifths (female) as long as 

 the hind femora. Pronotum feebly expanding posteriorly, the disk 

 broadly convex, passing by a distinct though slight ruga or rough 

 angulation into the vertical lateral lobes, these lateral carinae marked, 

 at least in the male, by a slender fiavous stripe, followed beneath on 

 the lateral lobes by a slender (female) or broad but posteriorly narrow- 

 ing (male) piceous postocular band, mostly or wholly confined to the 

 prozona; median cariiia percurreut and distinct, but duller on the
