102 LABIDUEIDiE. 



work, it is convenient to regard L. icterica, Serv., Kirby's Asiatic 

 form, as a subspecies, variety or race of L. riparia, scarcely 

 deserving a distinctive name ; and the dwarfed, dark, unarmed 

 form, with no anal points, so common in India, as variety inermis^ 

 Brunner. 



Subfamily V. PARISOLABIN^. 



This small group was formerly attached to the Brachylahhup, 

 with which it has several features in common, such as the long 

 slender tarsi, with long second segment, few antennal segments, 

 and almost rectangular meso- and metasterna. 



The antennae are, however, longer than in that group, and this 

 shows affinity with the Lahichmna', as also the convex, subparallel 

 body, long tarsi, and absence of glandular folds. For these 

 reasons, as well as the fact that the metasternum is truncate, it 

 appears to be more nearly related to the Labidurina' than to the 

 Psalime. 



Two genera are known ; one, Parisolahis, Yerh., contains a 

 single species occun-ing in New Zealand ; the other, Pseudisolabis, 

 with one species in New Zealand and two in India. 



Genus PSEUDISOLABIS, Bm;: 



Pseudisolabis, Burr, (08^) p. 254. 



Type, P. ivcdl-eri, Burr. 



Antennae with 15 segments, the fii-st long, strongly clavate; 

 second minute, cylindrical; third cylindrical, long, but not so 

 long as the first ; fourth minute and globular, not longer than 

 broad ; fifth longer than fourth, a little longer than broad ; the 

 rest gradually lengthening, but none equalling the third in length, 

 rather thick, "cylindrical, but the joints distinctly constricted. Head 

 not sharply triangular, rectangular posteriorly ; the occiput punctu- 

 late and pubescent ; the frons smooth and tumid ; the frontal 

 impressions obsolete. Pronotum subquadrate, the anterior and 

 posterior margins parallel and truncate, slightly broader posteriorly 

 than anteriorly and broader than long, a trifle broader than the 

 head; sides straight, gently diverging posteriorly. Mesonotum 

 transverse, parallel-sided, with no keels. Metanotum broader than 

 the mesonotum, the posterior margin gently sinuate. Prosternum 

 about double as long as broad, parallel-sided. Mesosternum trans- 

 verse, posterior margin truncate. Metasternum transverse, the 

 posterior margin truncate, Pemora rather thick, especially the 

 anterior pair ; tibiae and tarsi slender, second segment of latter
