ivitli remarks on some aberrant genera of the Scoliidse. 85 



the base of the anterior wings, an interrupted band on the first dorsal 

 segment of the abdomen and a transverse band on each side of the 

 second, third and fourth segments, most widely divided on the second, 

 yellow; femora, tibiae and tarsi ferruginous; tegulse testaceous. 

 Wings hyaline, faintly tinged with yellow, nervures ferruginous. 

 Length 14-15 mm. 



Hah. Rio Grande do Sul. 



As in other species of the genus the division between 

 the first and second ventral segment is very much less 

 deeply marked than in Myzinc, and the posterior coxse 

 separated. 



The male sent with this species differs from the type of 

 antennata by the slightly longer pronotum, the rather 

 stronger punctures on the head and the very slightly longer 

 antennae. I do not think these differences sufficient to 

 merit specific rank. 



Antliohosca natalica, n. sp. 



$. Clypeus flat and subtriangular, the apical margin depressed. 

 Head shining, sparsely punctured, very finely on the vertex, more 

 coarsely on the front. Antennte inserted as far from each other as 

 from the eyes, the front depressed round their base. Eyes rather 

 small, almost touching the base of the mandibles, but not reaching 

 quite as high as the posterior ocelli. Thorax sparsely punctured, 

 shining ; the pronotum as broad as the head, slightly but broadly 

 emarginate anteriorly, very large, nearly twice as long as the meso- 

 notum, extending backwards to the tegular, the posterior margin 

 almost sti'aight ; the scutellum broadly rounded posteriorly. Median 

 segment rather short, minutely punctured. Abdomen broader than 

 the thorax and longer than the head, thorax and median segment 

 combined, very finely punctured, with a row of large setigerous 

 punctures just before the depressed apical margin of each segment, 

 the pygidium clothed with coarse fulvous pubescence. The tarsal 

 ungues are bidentate, but not so strongly as in most extra- Australian 

 species of the genus, and the anterior tarsi are pectinate. The radial 

 cell is rounded at the apex ; the first recurrent nervure is received 

 just beyond the middle of the second cubital cell, the second just 

 before the middle of the third cubital cell. 



Black ; the pubescence grey, except on the pygidium ; the tarsi 

 and spines of the anterior tibise fusco-ferruginous, the spines of the 

 intermediate and posterior tibiae whitish ; the tegulse and the sides 

 and apical margins of the abdominal segments testaceous brown.
