2OO ENTOMOLOGICAL NEWS. [May, 'l6 



taxy of the head as follows : A median group of four very small spines 

 just behind the transverse area, four slightly larger near the base of 

 each antenna, three along the inner edge of the chitinized area of the 

 temporal margins, two long hairs and a short one at each posterior lat- 

 eral angle and a median pair of two small hairs on the occiput. On 

 the ventral side a single hair near the base of each antenna. 



Antenna conspicuously long, the first segment longest and widest, the 

 remainder becoming successively smaller. 



Thorax shorter and considerably wider than the head and with con- 

 vex lateral margins. A single long hair on each "shoulder" and one 

 just in from each mesothoracic spiracle. Sternal plate irregularly 

 shaped, longer than wide. Legs very large and stout, of the type com- 

 mon to the genus. 



Abdomen elongated oval, each segment with a single row of hairs. 

 First segment with a median group of four hairs, the outer ones very 

 small, the inner ones quite long. Second segment with two long me- 

 dian hairs and with four very small hairs between each of these and 

 the margin. Third segment with two long median hairs, four very 

 small hairs between each of these and the margin and a long hair close 

 to the margin. Fourth segment with three long median hairs, two very 

 short hairs and two long hairs near each lateral margin. Five with 

 median group of four and lateral groups of three long hairs. Six, 

 seven and eight with median groups of five or six and lateral groups of 

 two. Nine with five very long hairs. Chaetotaxy of ventral side very 

 similar except that there is no row of hairs on the eighth segment. 



Spiracles rather small. Gonapods blunt and rather short, each with 

 a fringe of short hairs along its inner margin. Immediately behind 

 each gonapod is a long sharply-pointed process with three or four 

 hairs on each side at its base. A group of two or three long hairs at 

 each posterior lateral angle of the ninth segment. 



Description of male. Much smaller than the female and with a 

 slightly reduced number of hairs on the abdomen, but in other respects 

 very similar. Genitalia very heavily chitinized, the basal plate long and 

 slender, about twice the length of the parameres. Genital plate lyri- 

 form. 



Triphleps insidiosus Say Sucking Blood (Hem., Het.). 

 One day near the end of October, while collecting insects at White 

 Heath, Illinois, I had the experience of being bitten by a specimen 

 of Triphleps insidiosus. A companion also had the same experience. 

 The species is well known as being of predaceous habits, but I do 

 not recollect having seen records of it attacking man. J. R. MALLOCH, 

 Urbana, 111.
