-fil. Gnathoenia irrorata sp. nov. 



i. G. iiiarra ; cinereo-pubesceiis, siijira mnltis pilis erectis vestita. Caput 

 olivaceo-lirimneum, distinote canaliculatum. Prothorax capitis colore, disco spar- 

 sissime minute piiuctnlatiis, latevaliter puuctis irrossioribus instruc.tns ; dente laterali 

 sat magfno; basi transverse sulcata. Elytra minute nifrro-lirnnneo-macnjata, basi 

 extrema conspicne grannlafa, <>-rosse ]]nnctata. post basim snbito miuntins punetulata; 

 (■alio liniuerali tiiberculato. 



Long. 18 mm., elvtr. 12, lat. s. 



Antennae black, witli a feeble tint of jiitchy colour ; base of the joints a little 

 greyer than the remaining. The sparse and minute punctuation of the prothorax is 

 stronger above the lateral teeth. Scutellnm olivaceous brown, with the sides grey. 

 Elytra covered with a grey pubescence and with very small brownish black spots, 

 whicli are somewhat denser in the middle and at the apex ; base coarsely punctuated, 

 the punctures confluent at the shoulders, the iutei'stices forming grannies chiefly at 

 the basal margin and underneath the shoulders, the latter bearing a rather strong 

 tubercle. Behind the base the punctures diminish in size rather suddenly, and are 

 minute from the middle to the tip. Each puncture of the upper surface bears a 

 short and black setulose uaii-. Under surface usually clothed with an ashy grey 

 pulicscence ; apex of the ultimate segment of the abdomen covered with longer hairs 

 of a somewhat fulvous colour. Ajiical part of the tibiae black, except the extreme 

 tip, where the hairs are yellowish, as in the middle of the intermediate tibiae and on 

 the underside of the tarsi. Mesosternal process with a blunt tubercle in front. 



Hab. Kuilu (A. Mocquerys, 1892). 



Its nearest allied species is On. renevfft Thorns., which has the punctuation 

 much denser and coarser at the sides of the prothorax, the basal transverse 

 groove shallower, the punctuation ol' the ajjical half of the elytra coarser, with tlie 

 punctures forming short rows, chiefly near the outer margins. The setulose hairs 

 are sparser in G. eenefea, and the elytra of the latter are spotted with a, white 

 pubescence, the spots arranged here and there in longitudinal rows.

1 have some doubt if the specimens l'n)m Kuilu and Loanda really belong to 

 G. venerea, as all examples of the very large series have a more or less large 

 irregular white patch on each elytron iu front of the middle. The greyish pubescence 

 of the middle region of the elytra is absent in most specimens, and the elytra are a 

 little more convex and slightly longer than in the specimen from " (,'ougo." 1 

 propose for this form from Kuilu and Loanda the name 0. venerea ab. alboplagiata.
