Polyphaga suhhyalina, n. sp. 



(Fig. 12 and 15). 



Type : \$, from Persia, Qazvin, 4,000 ft, 25-8-19. (P. A. Buxton). 

 Co-types : 2 ^, same locality, 30-9-19. 



^ . Medium sized species ; form elongate, coloration very pale, not very 

 hairy. Head small, occiput and forehead black with long reddish hairs, face and 

 mouth parts very pale yellowish. Eyes very large, black, a little more approxi- 

 mate than the ocelli ; these are big, yellow, the space between them forming a 

 rounded keel. Antennae rather thick, yellow. Maxillary palpi yellow, the 

 3rd article longer and thicker than the 4th, the 5th comparatively very short, 

 truncate. Pronotum small, short and broad, its anterior margin fringed with 

 long hairs, its surface covered with short, silky, reddish hairs ; general shape 

 regularly oval, the anterior margin feebly truncate, clearing the summit of the 

 head ; disk slightly convex, adorned with symmetrical brown lines, forming 

 a triangular impression. Abdomen broad, whitish, almost glabrous ; supraanal 

 plate small, rounded at the apex ; subgenital plate a little a symmetrical, 

 with no style, its posterior margin concave, lined with short spinuliform hairs, 

 angles rounded. Cerci short, yellowish. Genital valves short, folded on the 

 right, presenting a long hook on the left. 



Legs yellow, rather short. Front femora bearing long, irregular bristles ; 

 tibiae armed with 8 spines round the apex and 1 on the upper margin ; tarsi 

 long and slender, the metatarsus equaling the other joints together. Inter- 

 mediate femora bearing scarce long bristles and armed with 1 external genicular 

 spine ; tibiae armed with 7 long apical spurs, 6 superior (2 ext., 2 med., 2 int.), 

 and 2 inferior spines (1 ext., 1 int.). Posterior femora armed as the intermediate 

 ones ; tibiae with 7 spurs, the longer one much shorter than the half of the 

 metatarsus, 11 superior regularly disposed (5 ext., 3 med., 3 int.), and 5 

 inferior spines (2 ext., 3 int). Tarsi long, all the articles covered with spinelets ; 

 arolia between the claws small. 



Elytra extending much beyond the apex of abdomen, almost transparent with 

 numerous small greyish spots and the costal area whitish ; humeral vein send- 

 ing 6 or 7 branches to the internal margin ; branches of the median vein very 

 numerous, 12 to 14 ; anal field short. Mediastinal vein with a small inferior 

 lobe. Wings transparent except a few small greyish spots near the apex and 

 a narrow white opaque band along the anterior margin in its apical midst 

 ulnar vein with 5 branches; 1st axillary vein with 10 branches. 



Length of body, 13 mm.; length of pronot., 3*5 mm. ; width of pronot., 6 mm. j 

 length of tegmen, 19'5 mm.; width of tegmen, 7 mm.; post tib. 5'6 mm.; post, 

 metatarsus, 6 mm. 



Although looking much like H. livida Burm., at first sight, this species belongs 

 to the algerica group, having the spines of the posterior tibiae regularly disposed 

 along the whole length of the tibia. H. Roseni Brancs, seems to be a very close 

 species but Beancsik does not speak in his description of the disposition of the 

 tibial spines ; anyhow, the shape of the pronotum is different from that of the 

 present species, the elytra and wings are shorter and the tarsi possess no arolium. 



Polyphaga africana, L. 



Mesopotamia: Azijiysh, R. Tigris, 1-11-18, 1 J ; under flood refuse, slopes 

 of Jebel Hamrin, 1 adult and 2 young 5 ( ? )• 



The male specimen here referred to agrees quite well with the good figure of 

 this species given by Savigny (Descr. de I'Egypte, Orth., pi. II, fig. 11), but the 

 anterior part of the pronotum is not whitish ; I do not think this colour variation 

 is sufficient to authorize the creation of a species or even a geographical race. 

 There is a very distinct small arolia between the tarsal claws and the posterior
