tegmina being sharper and with a relatively narrower and more 

 evenly attenuate marginal field. The female of bvmaculata is 

 larger than the same sex of hrevipennis. 



A representative Independencia male measures : length of body, 

 17.5 mm.; length of pronotum, 4.3; greatest width of pronotum, 

 2.1; length of tegmen, 16.5; length of caudal fenmr, 4.5. 



We feel convinced that the records of this species from northern 

 Argentina and southern Bolivia refer to A. bimaculata.

 Apparently this is the first record of this striking species since 

 the original description. The specimen was badly damaged by 

 pests before coming into our possession. 



Metriomantis planicephala new species (Plate XV, figs. 32 and 33.) 



A very distinct member of the genus, differing from the pre- 

 viously known species in the female sex having the dorsum of the 

 pronotum tuberculate, in the different proportions of the same 

 portion and in the shape of the facial scutellum, which has an 

 acute angulation dorso-mesad. Doubtless a number of other 

 features found in this species are diagnostic, such as the great 

 flattening of the head and the general outline of the same, but 

 regarding these the descriptions of the other forms are not suffi- 

 ciently detailed to enable us to judge. The male sex of this 

 genus was previously unknown. 



Type. — cf ; Ceard, Mirim, State of Rio Grande do Sul, Brazil. 

 (Stanford Expedition: W. M. Mann.) [Acad. Nat. Sci. Phila., 

 Type no. 5270.] 



Size rather small; form robust, compact. Head moderately broad, very 

 deep, greatest depth but little shorter than the greatest width across eyes; 

 when seen from the cephalic aspect the general form of the head is circular, 

 slightly flattened dorsad and slightly produced ventrad in the buccal region, 

 when seen from the dorsal aspect the head is strongly compressed cephalo- 

 caudad, the face even faintly concave, the eyes slightly projecting cephalad 

 of the ocellar and scutellar regions; outline of vertex, when seen from cephalic 

 aspect, arcuate with a slight median truncation; the distance from the median 

 section of the vertex to the dorsal margin of the facial scutellum subequal to 

 that from the latter point to the clj'peo-labial suture; ocelli small, distinct, 

 placed in a depressed triangle; facial scutellum about one and one-half times
