l-'.lt odes (tnnata, lo)igicollis and some others move with a slow, 

 majestic stride : when touched, they elevate 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. 



Hololcpta viicatcca was found abundantly in decomposing 

 Cereus oioatitcit^ while H. cacti seemed to be a strange to the 



region. 



Chilconis cacti always found on old mesquite trees which are 

 badly infested with various scale insects. 



Many forms of Tenebrionidse 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 ; Eusattus muricatus will leave their marks of character- 

 istic appearance. The larger Eleodcs making similar ones but

 burrows. 



Those of Dinoclcns differ somewhat, the tarsal joints bending 

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

 about the roots of plants. 



Cicindcla guttifcra found on wet sand along the Rio Verde, 

 very wild and unassociated with any other species. 



Allorhina mutabilis proves a great menace to the horticultur- 

 ist, the fruit trees seeming alive with them.

 vast numbers. 



The young willow shoots gave us Chalcolepidius rr />/>//, 

 bc/urnsii and tartarns, without any of the unpleasant experi- 

 ences of Wickham and others. 



Hippomclas sphcnicn* we found in November, and so closely 

 does it resemble 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.
