ton. Collops hipunctatus was seen, not very abundantly, on low 

 Compositae near town. Trichodes ornatus was taken on flowers, 

 particularly those growing on the higher altitudes among the 

 foot-hills. Clems nigriventris, C. mwstus and Thanasimiis un- 

 dulatus were all found running about the wood-pile in company 

 with the aforementioned Buprestidae. 



Few Scarabaeidae were met with, among them jEgialia lucus- , 

 tris, Aphodius hamatus (this latter under dung close to the lit- 

 tle swamp which furnished the Chlwnius), A. denticidatus and 

 A. vittatus. A single male of Odontoeus obesus was secured and 

 is of particular interest, sine« it is' Pacific in distribution. Mr. 

 Schwarz had, however, previously taken one at Veta Pass, al- 

 titude 9,400 feet. We took two species of Serica, one of them 

 like vespertina, while the other approaches troeiformis in ap- 

 pearance but differs in sculpture. A female Lachnosterna ruh- 

 iginosa was found floating in an irrigating ditch. 



Of Longhorns we took several. PrionuH californicus was 

 seen rarely, one specimen deserving note on account of reach- 

 ing a length of but 25 mm., about half the usual size of the 

 species. XylotrechuH undulatus, Plaglthmysus muricatulus, Acm- 

 ceops proteus, Moiiohanimus maculosus and M. scutellatiis were all 

 dwellers on the wood-pile. Some Chrysomelidse observed are 

 as follows : Coscinoptera dominieana on scrub oaks, C. vittigera 

 rather common on various low plants in company with Babia 

 4-guttata, Saxinis omogera, one specimen, Flagiodera oviformis 

 and Trirhabda eonvergens. On willows we saw Galerucella decora 

 with Dlsonycha 5-vittata and Crepidodera helxines. Tenebrionidae 

 were not numerous, but we took Trimitys priunosa under stones 

 orabout the roots of plants, iu company with Coniontls obesa, 

 C. ovalis and Eleodes brunnipes. Under ties along the railroad 

 were found a few each of Eleodes humeralis, E. extticata and E. 

 »i^nwa and a single Asida opaca. Helops difficUis was not rare 

 under pine needles or in the rubbish about the roots of plants. 

 It seems not worth while to enumerate the other Heteromerous 

 beetles found, and the rather small series of Ehynchophora. 



A collector going into this valley will find it interesting as an 

 example of the encroachment on rather high altitudes of many 

 species belonging more properly to the plains fauna. This 

 seems to result from the very gradual slope of the Arkansas 

 valley and the peculiar characteristics of the soil.
