40 ORTHOPTEROUS GROUP INSARAE 



(Abdominal segments not as much dilated.) (Lateral lobes of pro- 

 notum more or less bullate. Tegmina very long, abbreviate or 

 aborted. Wings with distal portion exposed in all but extremely 

 brachypterous females. Genicular lobes of cephalic and median 

 femora bispinose. Subgenital plate of male very long, supplied with 

 non-articulate styliform appendages or tubercles which vary from 

 rather long to short for the group.) Arethaea St8,l 



CALLINSARA Rehn 

 This genus, which includes the single species Callinsara clupeipen- 

 nis, has recently been described and fully treated by the senior 

 author.'^ Although nearer relationship is shown to Dolichocercus 

 than to the other genera of the group Insarae, the present genus 

 differs greatly in general appearance, tegminal structure and im- 

 portant characters of the armament of the limbs, form of fastigium, 

 pronotum, tegmina, wings and genitalia.^ This genus is at present 

 known only from the unique male type from the Misiones, in 

 extreme northeastern Argentina, South America, which speci- 

 men is in the collection of the Academy of Natural Sciences of 



Philadelphia.

Genus monotypic. Genotype — Dolichocercus latipennis [Hor- 

 milia latipennis] (Brunner) . 



This genus is a member of the Phaneropterinae and of the group 

 Insarae and is known only from Central America. It shows no 

 close relationship to any other genus of the group, but agrees with 

 Callinsara in the non-dilated abdominal segments which have 

 their dorsal margins not produced mesad.^

 pp. 361 to 364, figs. 25 to 28. 



^ The most important of these characters are given in the generic key for 

 the group Insarae on page 39. 



6 AoXixoj = long, and /cepKis. In allusion to the very long cerci of the male. 



6 The two South American species described as Hormilia fasciata and 

 Hormilia peruviana agree with the present genus in this character and are 

 certainly not members of the genus Insara. An attempt to correctly place 

 these species without an examination of the types would be unsatisfactory, 

 but it appears probable that one or both will be found to belong either to 

 the present genus or to closely allied new genera.
