species were found in numbers on the bare needle-strewn ground 

 under the conifers, especially in sunny spots. It was easier to capture 

 T. cceruleipes, but owing to their numbers series of both species were 

 taken without difficulty. The previous Californian records of the 

 species are from Sissons, Marble Valley, El Dorado County, Los 

 Angeles and Cuyamaca. 



Trimerotropis bifasciata Brunei-. 



A pair of this species were taken in dry brush and grass between 

 Rubio Canyon and Altadena, at an elevation of about 1,500 feet, 

 August 8. 



This species was scarce, but two specimens only being seen. The 

 previous records are from Los Angeles and Tehama County, California, 

 and Spokane, Washington. 



Trimerotropis koebelei (Bruner). 



This species was found to be common at Sentinel, Yosemite National 

 Park, August 31 and September 1, a series of eighteen males and three 

 females being taken, as well as a single female at another point in 

 the Yosemite Valley on the last mentioned date. 



Wherever collecting was done about Sentinel this species was found 

 and taken without difficulty. 



The series exhibits a moderate amount of variation in size, and the 

 lateral lobes of the pronotum have the ventro-caudal margin either 

 with a distinct obtuse angulation or well rounded, the great majority 

 having this region very slightly angulate. The coloration varies 

 somewhat in depth and slightly so in pattern, although the last is 

 chiefly due to intensification or weakening. In but one specimen has 

 the anal area of the tegmina any marked maculations, and then but 

 a number of scattered spots. The black bands between the eyes, one 

 above the antennse, the other below the same, are often almost as 

 distinct as in T. cincta. The dorsal one, however, is frequently absent, 

 but the ventral one is present more or less distinctly in all but one 

 male specimen, which latter with one of the females is remarkable 

 in having the pronotum and head ochraceous-yellow. The broad 

 white bars on the sides of the face are distinct in all but the two 

 individuals mentioned above, although weak in a very dull colored 

 female. The black markings on the lateral lobes of the pronotum 

 are present in practically all the specimens, while the tegminal bars 

 are distinct in all the specimens, although rather weak in several, 

 the width of the bars varying considerably. The three femoral 

 bars — median, preapical and apical — are marked in the majority of
