with square, strongly chitinized, black spot. Céphalothorax rather 

 broader than long broadest behind the spiracles, after which 

 suddenly constricted; spiracles large lateral, but not prominent; 

 céphalothorax from the spiracles to apex straight, oblique, broadly 

 rounded angled before the anterior margin, thence oblique to 

 mandibles apex ; truncate at apex. Immediately behind the mouth 

 there is a curved chitinized line directed to spiracles; behind the 

 head its ends are divided respectively in two small chitinoys pieces, 

 which caudaly reach the broadest part of the céphalothorax. The 

 mandibles prominent, transverse, triangular; their anterior margin 

 obtusely angled, with a sharp tooth at the apex internally. The 

 mouth orifice leads in a short funnel-shaped chitinized tube. The 

 abdomen consists of eight segments ; there are only three median 

 genital tubes opening in the brood canal. The male is unknovn. 

 The triungulinid larvae have been collected by D. A. O gl o blin 

 and shall be described as soon as 1 shall obtain that material. 

 The following table have been made by my brother with 

 Reichert binoculare microscope oc. IV and objective 30 ; with 

 eyepiece micrometer; 1 space = 18 jf/. The 21** measurement has 

 been made by the author from a glycerin preparate of the female 

 specimen from Bedrykowce. 



The measurements are given by number as follows: 

 I. — The width of céphalothorax at base. 

 II. — The maximum breadth. 



III. — The distance between the spiracles. 



IV. — The distance between the mandibles. 



V. — The length from the front edge of the spiracle to 

 the apex of the céphalothorax. 



VI. — The length from the base to apex of the cépha- 



lothorax. V 



VII. — The width of the head at base. 

 VIII. — The width of the mandible. 



IX. — The length of the mandible.
