THE CANADIAN ENTOMOLOGIST. 211 



be compared with this genus, and as only one Entomologist in the U. S. 

 reads Russian, I give here a translation (by Prof. J. D. Whitney, in Cam- 

 bridge, Mass.). 



Maracanda, nov, gen. 



Tibiae hand calcaratae. Antennae breves, robustae, clava elongata. 

 Palpi breves, labiales articulo ultimo valde dilatato. Pedes breviusculi, 

 tarsorum articulo primo multo longiori quam secundus, sed breviori quam 

 ultimus. Abdomen alis brevius. Alae elongatae, angustatae, post-costa 

 obliqua; alae posticae anticis paulo breviores j femina. 



This genus, by the want of the spurs on the tibiae, is related to Gym- 

 jiocnemia. The short, thick antennae, the construction of the palpi, how- 

 ever, make it impossible to put the species described below in the same 

 genus with G. variegata, the typical species of the genus Gyninocnoiiia. 



Remark — Myrmeleo)i ocadtus Walk, and M. mains Walk., from 

 Australia, also do not have spurs on the tibiae (in the description of these 

 species, however, this peculiarity is not mentioned). It is very probable 

 that both these species ought to be included in the genus Maracanda. 



I. Maracanda amocna, McLachl., n. sp., p. 2, pi. i., fig. i. 



Pallide flava. Antennae brunneae, vix pallido-cinctae. Caput thor- 

 axque lineis tribus longitudinalibus fusco-nigris supra signata. Abdomen 

 nigrum vel fuscum, utrinque et infra flavo-lineatum. Pedes flavi, femori- 

 bus extra nigris, tibiis in medio et ad apicem nigris, articulisque tarsorum 

 ad apices nigris. Alae albido-hyalinae, punctis plurimis (praecipae apicem 

 versus) nigris conspersae, venis venulisque albidis, nigrostriatis, pterostig- 

 mate nigro-signato, femina. 



Long. Corp. circ. 15 mm.; exp. alar. 34 to 40 m.m. 



Habitat in deserto Kisil-kum; five specimens were collected May 12, 

 187 1, in the region of sand-hills about 10 versts west of Djusebai Springs. 



Antennae longer than the head and the front part of the thorax, gradu- 

 ally passing into a thick elongated clavate form, cinnamon colored with 

 the exception of the basal joint ; the cinnamon color of the remainder of 

 the joints passes with a whitish color on the articulations ; the body is 

 bright yellow. The head has above three small elongated dusty lines, 

 which unite with each other in front ; on the side from the end of these 

 dark spots there extends a single dusty transversal line ; a single knotted 

 line of the same color is seen on each of the antennae ; finallv a single 

 elongated dusky line extends along the front of the head. The labrum is
