178 Mr. W. L. Distant on 



XVIII. — On some South-African Insects. 

 By W. L. Distant. 



I HAVE received some Longicorn beetles from the Rev. H. 

 Junod, collected by him at Delagoa Bay, two of which 

 appear to be undescribed and not included in the list of the 

 Delagoa Longicornia recently published in these pages 

 (ser. 7, vol. i. p. 378). 



Among some Sphingidse forwarded to me from the Pre- 

 toria Museum I found two apparently undescribed species 

 from the Lydenburg District of the Transvaal, the diagnosis 

 of which I take this opportunity to publish. 



COLEOPTEEA. 



Longicornia. 

 Fam. Cerambycidae. 



Hercodera marginata } sp. n. 



Testaceous ; head, pronotum, and femora reddish testaceous ; 

 eyes, antenna?, bases and apices of femora, tibia?, and tarsi 

 black ; elytra with the anterior, apical, outer, and sutural 

 margins and a transverse fascia beyond middle bluish black, 

 apical margin broadest. 



Head obsoletely punctured. Pronotum at the sides and 

 above covered with broad, shallow, regular punctures, giving 

 it a reticulated appearance. Elytra very thickly and strongly 

 punctate, the transverse fascia widest at sutural and outer 

 margins. 



Long, (two specimens) 9 and 12 millim. 



Bab. Delagoa Bay {Junod). 



This is the second species of the genus yet described. It 

 differs from H. jasciata, Gahan, by being less angular at 

 sides of pronotum and also in the elytral markings. The 

 punctures, as Mr. Gahan kindly informs me, are almost 

 exactly alike in both species. 



In the smaller specimen of the two on which this descrip- 

 tion is based the transverse fascia to the elytra is very narrow 

 and somewhat indistinct. 



Oxyprosopus delagoa, sp. n. 



iEruginous ; eyes, antennae, femora, and tibia? black ; tarsi 

 pale fulvous.
