and sternum closely and distinctly punctate. Scutellum :md 

 abdomen, immaculate ; basal segment closely and distinctly 

 punctate, with long but not dense pilosity, becoming stronger 

 basally ; central segments finely transversely aciculate, anus 

 glabrous and nitidulous ; terebra stout and black, with the spicula 

 red, a little longer than half the abdomen. Leys red, with the 

 coxae, trochanters, the hind tarsi and apices of their femora, and 

 the base and apex of their tibiae, black ; coxae and trochanters with 

 elongate white pubescence; hind calcaria unequal. Wiivjs clear 

 hyaline, with the nervures and stigma black ; radix and tegulae 

 infuscate, with the latter basally fulvous.

Type in Col. Xurse's collection. 



This species very strongly resembles A. planiariug, Grav., but 

 is a little smaller, with the metathoracic costa more distinct and 

 the petiole not canaliculate, the front marks of the niesonotum 

 and the pale markings both of the tibiae and hind tarsi are wanting, 

 and the abdomen is immaculate, though easily subfusiforni.

GEXOTYPE, L. sulphurifera, Grav. 



Head transverse and neither buccate nor elongately pilose ; 

 olypeus discrete, somewhat convex and apically rounded. Au- 

 tennse filiform or apically subattenua.te, with the flagellum normal ; 

 aj)ical joints not moniliform or discrete. Thorax subcylindrical, 

 longer than high ; niesonotum often striped ; inetathorax punctate 

 or scabriculous, with areola incomplete or often entirely wanting ; 

 basal costa of petiolar area usually distinct and strong ; spiracles 

 small and circular. Scutellum normal, often pale-marked. Ab- 

 domen narrow and deplanate, somewhat smooth, not tuberculate 

 or obliquely incised, usually closely and finely punctate or aluta- 

 ceous ; segments not apically elevated, the basal elongate, sessile, 

 rarely subquadrate ; hypopygium always covering base of terebra 

 and sometimes nearly reaching the anus ; terebra slender and 

 usually as long as, or longer than, the abdomen. Legs somewhat 

 slender, with the tarsal claws not pectinate, though sometimes 

 eetiferous. Wings with a more or less distinct, and often sub- 

 petiolate, triangular areolet.

Unfortunately, I am compelled to leave this genus in a somewhat 

 unsatisfactory condition ; such species described by Cameron as I 

 have not seen must remain here, since he makes no mention of 

 their metathoracic spiracles ; but in every case in which I have had 

 the opportunity of examining the types I have found his insects 

 to belong to the genus Syzeuctus. The representatives of the
