Davis: Northern Florida Orthoptera. 



99 



Mandibles, lower edge of front and base of antennae beneath, black. The 

 upper surface of the head and pronotum with a faint line not well defined 

 on either side of a yellowish color, which is bordered interiorly with blackish, 

 the enclosed space between the black lines brown in color. The stripes ex- 

 tend from the fastigium backward to the base of the thorax. Fastigium sharp 

 pointed, about as in subapterus, slightly bent downward and tipped with black. 

 Inferior basal tooth of fastigium also tipped with black. Antennae longer than 

 the body, with the joints annulated with blacS. Abdomen with a well-defined 

 interrupted carina. The femora and tibiae of all of the legs blotched with 

 brown, and the tips of the spines black. The supra-anal plate with the V- 

 shaped notch narrow and the inner sides but little curved, not considerably 

 so as in micanopy. The excavated part surrounding the notch has the sides 

 declivitous, more so than in any other Belocephalus thus far described. The 

 outer extremities of the subgenital plate are not bent upward and inward and 

 produced into points. 



Male, Mm. 



Length of body 24.0 



Length of fastigium beyond base of antennae 



Length of pronotum 



Length of tegmen 7. 



Length of caudal femur < 13. 



B. excavatiis. 



B. subapterus. 



Only the type was collected, but the supra-anal plate is shaped 

 so differently from that of any other known Belocephalus that it is 

 evidently distinct. This species should be considered in the tables 

 for the determination of Belocephalus, published in this Journal in 

 September, 1914, next to subapterus, from which it may be easily 

 separated by the accompanying excellent figures by Mr. Louis H. 

 Joutel.
