212 ENTOMOLOGICAL NEWS. [Sept., 'O2 



mentum (Fig. 2, B, snt) devoid of hair. Hairs on lateral margins of man- 

 dibles quite long and stiff ; one spine in front of distal mandibular tooth, 

 from two to four spines in each space between consecutive teeth, most 

 often three, least often four. A villosity on each anterior lateral margin 

 of the mesothorax above, inward from which is a smaller one. A villosity 

 on each posterior lateral corner of metathorax above. A row of villosities 

 on each side of the ventral surface of the abdomen, parallel with the 

 margin. Two parallel rows of villosities (or rather tufts of bristles) on 

 each side of abdomen. There is a transverse row of spines on upper sur- 

 face of last abdominal segment ; on the ventral surface a row of spines 

 near the free border each side, the anterior spine longest, each succeed- 

 ing one shorter ; another row of three spines each side, parallel to the 

 preceeding ; a pair of smaller spines near the anterior border ; a row of 

 six stout cylindrical spines on posterior border, preceded by a row of 

 four similar spines. The larva is yellow with brown spots and markings; 

 all hairs are black. Five spots on dorsal surface of head ; one larger 

 spot on anterior border, behind which is a pair of triangular ones, suc- 

 ceeded by a pair of elongate spots reaching from the middle of the head 

 to the posterior border, nearly touching behind, and diverging in front. 

 Two pairs of large spots on ventral surface of head, set far apart ; anterior 

 pair narrow, diverging in front ; posterior pair larger, nearly circular. 

 Two elongate spots on each side of head, one near the middle, one near 

 posterior border. Ocular peduncles and eyes black. Antenna yellow, 

 shaded into fuscous toward tip. Curved portion of mandible and tips of 

 teeth ferruginous. Terminal segment of palpus brown. The thorax has 

 on upper surface a mid-dorsal broken stripe and two longitudinal rows of 

 spots which diverge behind ; thorax is spotted below. The metathorax 

 has a black spot near each anterior lateral border above. The metathorax, 

 coxae and femurs are sometimes striped longitudinally ; all the ungues are 

 fuscous. The abdomen has a mid-dorsal broken stripe, on each side of 

 which are two longitudinal rows of spots curving inwards behind, the 

 inner one of smaller spots ; first and second segments each having a black 

 spot near each lateral border above ; a mid-ventral row of minute spots, 

 on each side of which are two rows of spots curving inwards behind. 



Six specimens from Galveston, Texas, June, 1900. 



Myrmeleon rusticus Hagen. 



Larva. Length, including mandibles, 14 mm. Similar to the pre- 

 ceeding (I will describe this larva by comparing it with the preceding). 

 Head slightly variable in shape, generally narrower behind. Antenna of 

 thirteen to fifteen segments. From two to three spines between each two 

 consecutive madibular teeth, more often two. Markings variable in si/e 

 and shape in individuals of the same locality and to a greater extent in in- 

 dividuals of different localities. Specimens from I. art-do, Texas, an- not 

 very different from J\L texanus in marking, while the markings on speci- 

 mens from Austin, Texas, are larger and darker, being fuscous or black.
