Thyanta custator Stal, Euum. Hemipt., ii, 34, No. 2. 



One specimen from near Manitou, Colo., August 16. The specimens 

 that I have thus far seen from Eastern Colorado have been of a pale 

 sickly green, with the yellow or rufous of the pronotum not very distinct.

 Thyanta perditor Stal, Enum. Hemipt., ii, 34, No. 1. 



One specimen from near Pueblo, Colo., August 10. The form from 

 Eastern Colorado has a shorter lateral tooth to the pronotum than that 

 of Mexico and the West Indies. Several specimens from Arizona vary 

 in the length of these processes, but in none are they so long as in those 

 from Cuba and San Domingo. In Western Hayti, they occur quite 

 abundantly in the neglected, and weedy pares of gardens. A few spe- 

 cimens were obtained by myself in that country from the Palma Christi, 

 or castor-oil plant. In the tropics, they acquire their richest green 

 ground-color with the bright carmine band upon the pronotum.

 Murgantia histrionica Stal, Enum. Hemipt., ii, 37, No. 4. 



This widely distributed pest of the vegetable garden is now sufficiently 

 common in Colorado to be of serious injury to the farmers. I found 

 specimens near Denver in the region of irrigation, and also near the 

 city of Golden, August 6. Dr. Packard also took specimens at the lat- 

 ter locality on July 3. No specimens occurred to me south of Denver. 

 Perhaps the reason why I did not find it elsewhere was owing to the 

 fact of the first brood being over, and the time had not arrived for the 

 appearance of the second brood. I swept the weeds on the cultivated 

 grounds west of Colorado Springs, and also in the valley of the Arkan- 

 sas Eiver near Pueblo, and from the vicinity of Caiion City up to and 

 in the Grand Caiion of the Arkansas, but I did not meet with specimens 

 in either of those places.

I obtained the larva in Clear Creek Caiion August 6, and Dr. Pack- 

 ard found the imago near Blackhawk, Colo., on July 2.
