Eleodes annata, lo7igicoUis and some others move with a slow, 

 majestic stride ; when touched, they rlevate the abdomen, 

 walking off, apparently, on their heads ; the name " kangaroo 

 bugs " has been applied to them by the ranchmen. 



Asidas are retiring and found, as a rule, under some protect- 

 ing material. 



Hololepta yiicateca was found abundantly in decomposing 

 Cereiis giganteiis, while H. cadi seemed to be a strange to the 

 region. 



Chilcoriis cacti always found on old mesquite trees which are 

 badly infested with various scale insects. 



Many forms of Tenebrionidae are nocturnal in their habits ; 

 the intense heat of day often kills them when almost in their 

 burrows. This we .saw in many instances in the sandy bot- 

 toms along the Rio Verde. 



Curious tracks left in the sand by beetles at once attract the 

 eye ; E2isattus muricatus will leave their marks of character- 

 istic appearance. The larger Eleodes making similar ones but 

 longer, and by following these we were able to locate their 

 burrows. 



Those of Dinoc/eus differ somewhat, the tarsal joints bending 

 inward to help them along, and they are always to be found 

 about the roots of plants. 



Ciciiidcla gtitti/era found on wet sand along the Rio Verde, 

 very wild and unas.sociated with any other species. 



A/lor/mia imitabilis proves a great menace to the horticultur- 

 ist, the fruit trees seeming alive with them. 



Cotalpa co?isobrina is another pest, some seasons appearing in 

 vast numbers. 



The young willow shoots gave us Chalcolepidius zeebbii, 

 behrensii and tartarus, without any of the unpleasant experi- 

 ences of Wickham and others. 



}[ippomeIas spheniciis we found in November, and so closely 

 does it re.semble the branches of the mesquite that it requires 

 close searching to find them. 



Flushing the banks of streams with water furnished many 

 species of riparian beetles, but the larger number were taken 

 at the electric light, as were the majority of Staphylinidae.
