Tropizaspis steindachneri. 



Arytropteris steindachneri Herm., Verb. Zool.-Bot. Ges. Wien, XXIV. 204-205, 

 PI. 6, Figs. 98-102 (1874). 



Tropizaspis steindachneri Scudd., Can. Ent., XXVI. 180, 18.3 (1894). 



This is altogether the commonest form of Tropizaspis, to judge from 

 the specimens I have seen, and is somewhat variable in coloration and 

 markings, though usually rather uniformly testaceous or fusco-testaceous, 

 with the upper part of the lateral lobes of the pronotum infuscated. 

 Herman states that the median carina of the pronotum stops before the 

 bind border, but it is percurrent in all the specimens I have seen, 46 in 

 number. 



It was originally described from Puget Sound. I have seen specimens 

 made on the northwestern boundary survey by Dr. Keunerly ; from Oi'e- 

 gon (Oregon City, Harford; Mary's Peak, Benton Co., Sept. 16, Divide, 

 Sept. 12, Drain, Sept. 11, Gleudale, Sept. 9, and Siskiyou, Sept. 6, 

 Morse); California (Mendocino; Napa Co., Edwards ; Napa or Sonoma 

 Co., Osten Sacken) ; and El Paso, Texas, Uhler. I have also specimens 

 fi'om Uhler's collection marked as taken by Suckley in Nebraska, but I 

 am inclined to think this an error, as Suckley collected also in the north- 

 west, and Bruner has not given it in his Nebraska lists. 



Tropizaspis diabolica sp. nov. 



Head moderately large, castaneo-testaceous, the fastigium slightly 

 broader than the basal joints of the antennte. Pronotum with rather 

 feebly clepsydral disk, which is considerably more than half as long again 

 as broad, broadest but little behind the middle of the metazona, and of 

 nearly equal breadth throughout the posterior half of the pronotum, 

 the lateral carinre not elevated on the prozona, on the metazona a little 

 elevated but blunt; hind border margined, broadly rounded ; median 

 carina feeble, subequal, percurrent ; the whole disk uniform castaneous, 

 transversely pectinate, feebly rugose posteriorly, the lateral lobes fusco- 

 fuliginous on upper half, castaneo-testaceous below. Legs luteo-testaceous, 

 the fore and middle femora twice banded with blackish fuscous, the hind 

 femora coarsely and a little transversely spotted above witli blackish 

 fuscous, much more than twice as long as the procotum, the basal portion
