WILLIAMS: LARRID.^ OF KANSAS. 149 



Clark county. Kansas; F. H. Snow. There is also a j' in the 

 U. S. N. Museum from Mesilla Park (New Mex.). 



This may eventually prove to be the j of chilopsidis, which, be- 

 sides having the same habitat, it resembles a good deal. 



Larropsis chilopsidis (Ckll. & Fox). 



Ancistromma chilopsidis Ckll. & Fox; P. Ac. Philad., 137; 1897. 5 . 

 Ancistromma zerbeii Viereck; Trans. Am. Ent. Soc, XXXII, 208-9;

o . Anterior margin of clypeus rounded out, slightly and narrowly 

 emarginate mesad, obtusely bidentate laterally, with large sparse punc- 

 tures; front and vertex with well-separated and moderately small punc- 

 tures; antenna not long, of nearly uniform thickness, joint 3 very slightly 

 longer than 4; interocular space at vertex more than the length of anten- 

 nal joints 2-4; prothorax and mesothorax very finely and closely punc- 

 tate, nearly granular; mesopleurse closely punctate; disc of propodeum 

 with very fine striae, which are transverse in the middle and more or less 

 diverging at the base and apex; the propodeum hardly sulcate except at 

 base and apex, the posterior face with a sulcation, this face and the sides 

 indistinctly fine striate; legs strongly spinose, the fossorial comb of quite 

 long bristles; abdomen shining, a few punctations ventrad; pygidial area 

 polished, rather broad, the sides bowed out, quite sparsely punctate and 

 pilose at apex. "Testaceo-castaneus; head black excepting the greater 

 part of the clyjjeus, mandibles and antennse, which are castaneous" (Vier., 

 for zerbeii) ; antennae darker apically; sternum of thorax largely black, 

 also a portion of the base of cox»; wings yellowish hyaline, venation 

 yellowish. Pronotum and mesonotum with considerable shoit, pale, brown- 

 ish pile; pygidium with a few pale reddish-brown hairs at apex. Length, 

 10-12 mm. 



Five J 5 , Clark county, Kansas; F. H. Snow. One of the above 

 specimens has the thorax nearly all black and the apical half of the 

 antennae nearly black. 



While at the Philadelphia Academy of Sciences last winter, the writer 

 noticed the resemblance of zerbeii Vier. to chilopsidis Ckll. & Fox. Not 

 having the first species with me to compare, notes were taken on the type 

 chilopsidis. These were found to fit zerbeii well, and a specimen of the 

 latter sent to Mr. Fox, at Philadelphia, to compare with chilopsidis proved 

 in his opinion to be the same as cltilopsidis. The insect is allied to veg- 

 etoides, notwithstanding the difference in color, etc., between the two. 



Tachytes Panzei'. 



Panzer; Krit. Rev., II, p. 129; 1806. 

 Syn. Lyrops Illig.; 1807. 



Form stout to rather elongate, more or less pubescent, sometimes bee- 

 like. Heal as wide as to slightly wider than thorax; antennae usually 

 rather stout; ocelli bordering on a swelling which is more or less furrowed 

 longitudinally, the po.=terior pair vei'y elongate, flattened and hooked 

 posteriorly, their anterior portion almost longitudinal in position; man- 

 dibles emarginate beneath, with one or two teeth within; propodeum
