over the entire state and is becoming a veritable nuisance, even 
in the smaller towns of the prairie region. 
Periplaneta americana Linn. Specimens of this large south- 
ern form have been found at Carbonado, Grand Junction, Little 
Rock and Ames, but in every case in buildings where bananas 
were sold, and it is doubtful if they have gained a permanent 
foothold. 
Fam. PHASMiD^ — Walking Sticks. 
Diaplieromera femorata Say. Common throughout the tim- 
bered portion of the state. Either this or an allied species has 
been observed very commonly on the prairies of the north- 
western portion of the state, during August and September. 
Fam. Gryllid^— Crickets. 
Tridactylus apicalis Say. This small species was found 
rather commonly as nymphs, along the margin of a small 
stream in August and September, and again the following 
April. Adults were taken in July. * 
Gryllotalpa borealis Scudd. 
Gryllotalpa Columbia Scudd. This and the preceding species 
are found only in the southern portion of the state. Are they 
distinct? 
Gryllus abbreviaius Serv. The most abundant species in the 
state occurring everywhere. Sometimes occasions considerable 
loss in the grain raising sections by cutting the bands of the 
shocked grain. 
Grijllus luctuosus Serv. Rare. 
Gryllus pennsylanicus Barm. A few specimens of a broad 
headed cricket that has been referred here were taken from 
the timber in July. 
Nemobius fasciatus DeGeer. Occurs with abbreviatus in the 
fields. 
Nemobius carolinus Scudd. Common in the woods. 
Anaxiplius pulicarlus Sauss. A number of these small light 
colored crickets were taken while sweeping in the woods in 
July. 
Apithes agitator Uhl. One specimen of this southern form 
has been received from Lee county. 
(Ecanthus fasciatus Fitch. Abundant everywhere during the 
latter part of the season. 
(Ecanthus angustvpennis Fitch. Examples of this species 
appear several weeks earlier than any of fasciatus, and may be 
found rather commonly on the prairie.
