opaque ; scutellums shining, smooth, sparsely covered with 

 short fuscous hair ; the basal scutellar keel stout, sharp, 

 white at the apex, and extending to the middle. Base of 

 median segment depressed at the base, the furrow smooth, 

 slightly curved, petiolar area open at the base, areola longer 

 than broad, rounded at the base, rounded inwardly at the 

 apex ; posterior median area slightly widened at the base, 

 almost smooth, only obscurely transversely striated ; the 

 supra- external area has some scattered punctures, the tooth- 

 bearing coarsely punctured, the spiracular finely punctured 

 at the base, the rest obliquely striated ; the posterior inter- 

 median coarsely obliquely striated ; the teeth indistinct. 

 Propleurse punctured above, below smooth, the apex in the 

 middle with some stout punctures ; mesopleurse closely 

 punctured, the metapleurae more strongly, with the punc- 

 tures somewhat more widely separated. 



Algathia Rothneyi, sp. n. 



Agrees closely in coloration with A. varipes, except that 

 it has a yellow mark on the mesopleura; otherwise differing 

 in having the base of the metanotum opaque and aciculated, 

 the keels bordering the petiolar area are longer, the areola is 

 not smooth, the teeth are more distinct, the hinder femora 

 have only the apical third black, and the scutellar keels reach 

 to the apex. 



Black ; the head below the antennse, mandibles (except 

 the teeth), palpi, the inner orbits above, the line narroAved 

 below, the apical three fourths of outer orbits, edge of pro- 

 notum (the basal half of the line dilated and acute at the 

 base), the tubercles, a mark on the hinder edge of raeso- 

 pleurae (longer than wide and obliquely truncated at the 

 apex), scutellums, the sides of the median segment (broadly 

 at the apex), a narrow band on the first abdominal segment 

 (roundly dilated in the middle), the apex of second broadly, 

 and the apical two entirely, pale yellow. Four front legs 

 rufous, their coxae and trochanters pallid yellow ; hinder legs 

 of a deeper red ; coxaa black, yellow above and within, the 

 basal joint of trochanters yellow ; the apical third of femora 

 and of the tibiae and the basal two thirds of metatarsus 

 black ; the rest of the tarsi pale yellow, except the apex of 

 the last joint. Wings clear hyaline, the stigma testaceous, 

 nervures fuscous. ? .
