254 Mr. M. Burr — Notes on the Forficularia. 



mine, brown, flat, and broad/' in the words of my rough 

 notes taken on the occasion. My specimen is black, not very 

 flat, and by no means broad. On carefully comparing it with 

 Verhoeff s characterization of Parisolabis, I find that it differs 

 in important particulars, and accordingly am obliged to erect 

 a new genus. 



Genus VI. Pseudisolabis, gen. nov. 



Corpus minute punctulatum, valde pubescens ; pars antica corporis 

 fere cylindrica ; abdomen sat depressum : antennae 15 eegmentis, 

 3 cylindrico, duplo longiori quam latiori ; 4 et 5 brevibus, globu- 

 laribus ; caeteris cylindricis, sat brevibus : caput minus triangu- 

 lare ; pronotum sublatius quam longius ; mesonotum carinis 

 nullis : pedes graciles ; tarsi longi, segmento 2 elongato : abdo- 

 men sat depressum, ante apicem subdilatatum, tuberculis late- 

 ralibus nullis, segmentis apicalibus lateribus convexis : segmento 

 ultimo dorsali transverso, baud angustato, margine postico trun- 

 cato : forcipis bracchia basi remota, basi ipso triquetra, deiude 

 cylindrica, angusta. 3 . 



The whole body is finely punctulate and covered with a 

 close yellowish pubescence. 



Antennae with 15 segments, the first 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 punctulate and pubescent ; the frons smooth and 

 tumid ; the frontal impressions obsolete. Pronotum sub- 

 quadrate, 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, with no keels. 



Metanotum broader than the mesonotum, the posterior 

 margin gently sinuate. 



Prosternum about double as long as broad, parallel. 



Mesosternum transverse, posterior margin truncate. 



Metasternum transverse, the posterior margin truncate. 



Femora rather thick, especially the anterior pair ; tibiae 

 and tarsi slender, second segment of latter rather long and 

 slender, about half as long as the third, the first about as 

 long as the second and third united. 



Abdomen rather depressed, gently dilated about the apical
