lateral carinae on tlie piouotiim and its 

 consequent much closer resemblance 

 to the Leptysmae. It also possesses 

 the rasp on the hind femora of the 

 male, noted by Morse in Pseudopomida. 

 The two genera may be separated by 

 the following table : — 

 a^. Plane of lateral foveolae of the 

 vertex inflexed ; eyes subacuminate 

 above, broadest below the middle ; 

 pronotum with distinct lateral carinae 

 in both sexes; mesothoracic lobes short, 

 well separated Pseudoponiala Morse. 

 a '^. Plane of lateral foveolae of the 

 vertex depressed but vertical ; eyes 

 regidarly elliptical, almost or quite as 

 rounded above as below, broadest at 

 the middle ; pronotum with no lateral 

 carinae or they are found feebl}- on tlie 

 metazona of the male ; mesothoracic 

 lobes moderately long, attingeiit or 

 subattingent Paropomala^ g^'^- nov. 

 I have before me three species be- 

 longing to this latter type, all coming 

 from the western half of the United 

 States. They may be thus separated : — 

 a '. Tegmina not reaching tip of abdo- 

 men or even tip of hind femora ; sub- 

 genital plate of male elongate, half as 

 long again as the last ventral segment. 

 b *. Testaceous ; antennae of female 

 as long as the hind femora ; median 

 carjna of pronotum rather coarse ; 

 mesothoracic lobes rugulose 



cyh'i/dr/ca Biun. 

 b'. Green or pallid; antennae of 

 female shorter than the hind femora ; 

 median carina of pronotum very del- 

 icate ; mesothoracic lobes smooth 



calamus sp. nov. 



(7". Tegmina reaching tip of abdomen 

 and surpassing hind femora ; subgenital 

 plate of male not very long, no longer 

 than the last ventral segment 



'jlrgata sp. nov. 



JMcsops wyomingensis Thom. also 

 belongs to this genus, if indeeil it is to be 

 distinguished from P. cyliinirica. It 

 comes from Wyoming. 



The first of these three species {Me- 

 sops cyliiidricus Brun. Proc. U. S. nat. 

 mus. xii, 48-49, 1S90) I have seen only 

 from Valentine, Nebr. (Bruner) and 

 Fort Collins, Colo. (Baker). Paro- 

 pomala calamus is from Lancaster, 

 Cal., Aug. I (A. P. Morse) ; I have 

 only seen 2 J" , i 9 . It is the slender- 

 est foim of the three, of a pale green 

 color with a slender hoary stripe run- 

 ning backward from the lower edge of 

 the eye, bordering narrowly the lower 

 edge of the pronotum. Of Paro- 

 po?iiala vlrgata I have before me 

 nearly a hundred specimens collected 

 by A. P. Morse at Mesilla, N. Mex., 

 Tune zc, ; between Gila Bend and 

 Yuma, Ariz., July 4; and in Califor- 

 nia at Palm Springs on bunch grass, 

 July 12, Cahon Pass, July 10, Lancas- 

 ter Aug. !, and Kern City, Aug. 4. 

 Generally of a pale green color with a 

 tendencv to becoming cinereous above, 

 it varies ;_;reatl3- froni having the sides 

 of the head, pronotiuii and thoracic 

 pleura wholly green to their being 

 chalky white on lower and dark fuscous 

 on upper half, sharply delimited; most 

 commonly the upper half is more or 

 less infuscated and the lower half pale 

 testaceous or sordid white ; the anten-
