Sept., 1909.] EwiNG : Nf.w American Orihatoidea. 127 



antero-lateral hairs but slightly curved, almost as long as the lamellar hairs. Pseu- 

 dostigmatic organ small, subcapitate. 



Abdomen subglobose. Dorsum with a very few minute, rudimentary hairs. 

 Genital covers much smaller than the anal covers and situated fully twice their 

 length from the latter ; anal covers approximate to posterior margin of ventral plate. 



Anterior pair of legs about as long as the body. Tarsus of leg I shorter than 

 the tibia ; genual one third as long as the tibia. Ungues tridactyle ; dactyles subequal. 



Length, 0.67 mm.; breadth, 0.45 mm. 



In sweepings from grass. Collected by C. A. Hart at the southern 

 end of Padre Island, Texas. Many specimens. 



This species is related to N. depilis but differs in the following 

 points : the lamellae are longer than in N. depilis, the body is larger 

 and darker in color, and the legs are longer. 



Notaspis pallida, new species. (Plate V, Fig. 22.) 



Reddish brown ; legs lighter than the body. 



Cephalothorax longer than broad. Lamella; a little over one half as long as the 

 cephalothorax. They are very narrow and are of about uniform width throughout. 

 Lateral lamella; indicated by a slight chitinous ridge. Lamellar hairs almo-t straight, 

 pectinate, as long as the lamella; themselves ; interlaraellar hairs similar to lamellar 

 hairs, erect and situated near the posterior margin of the cephalothorax ; anterior 

 lateral hairs strongly curved and about three fifths as long as the lamellar hairs. 

 Pseudostigmatic organ with recurved peduncle and large, clavate head. 



Abdomen three fourths as broad as long. From the shoulders there is a small 

 chitinous expansion which indicates a relationship to the Fterogasterna. Abdomen 

 with about two dozen rather long bristles mostly situated around the margin. Geni- 

 tal covers much smaller than the anal covers, each about one half as broad as long; 

 anal covers situated a little over their length from the genital covers and about one 

 fourth their length from the posterior margin of ventral plate. 



Tarsus and tibia of leg I subequal ; genual one half as long as the tibia. Un- 

 gues tridactyle ; dactyles unequal. 



Length, 4.48 mm.; breadth, 0.30 mm. 



In moss. Collected by the writer at Urbana, 111. Two specimens. 



Notaspis lamellata, new species. (Plate V, Fig. 23.) 



Very light yellowish brown. 



Cephalothorax as broad as long. Lamella; three fourths as long as the cephalo- 

 thorax, much broader in the middle than at either end ; no translamella or lateral 

 lamellx. Lamellar hairs straight, pectinate, about one half as long as the lamellae ; 

 interlamellar hairs small, erect, about three fourths as long as the lamellar hair; an- 

 tero-lateral hair but slightly curved and situated near the median line. This species 

 is rather peculiar in possessing a pair of hairs upon the rostrum slightly in front and 

 inside of the lamellar cusps ; rostral hairs almost equal to lamellar hairs. Pseudo- 

 stigmatic organ with slender recurved peduncle and sublanceolate head.
