Chelostoma Neoinexicanum, n. sp. 

 (J . — Length about 8 mm., black, with distinct narrow white hair- 

 bands on abdomen. Middle of anterior margin of clypeus curved upv/ards, 

 presenting a point from which the sides slope gently for some distance, 

 and then abruptly nearly vertically, the whole, seen from beneath, having 

 about the outline of a low house seen from one end ; some distance on 

 each side of this structure is a low projection of the margin. In general, 

 the insect looks just like Ashmeadiella bucconis, but the second tooth of 

 the mandibles is .short, and the front and vertex are as densely punctured 

 as it is possible for them to be. The last joint of the labial palpus is 

 conspicuously longer than the penultimate one. 



fjab. — Barela Mesa, New Mexico, at flowers of blue-bell ; June 28, 

 1903. {Anna Gohrman.) The genus is new to New Mexico. The 

 species will be easily known by the clypeal structure, as described. Miss 

 Gohrman also collected Osinia Brtineri, Ckll, at flowers of blue-bell at 

 Barela Mesa, June 28. The species is new to New Mexico. At the same 

 place, and on the same day, she also collected Anthidium maatiosum, Cr., 

 ^ (at loco flowers), a.x\d Synhaionia /rater, Cr. 



Halictus dematisellus, n. sp. 



$. — Length about 5 mm.; head and thorax olive green; abdomen 

 shining bright orange-ferruginous, not at all dusky at apex, the third and 

 fourth segments each with a small round black spot near the base on each 

 extreme side ; wings short, iridescent; tegulse, nervures and stigma pale 

 testaceous. In nearly all respects this agrees with H. pidus, Crawford, 

 but it differs conspicuously in having the abdomen only very scantily 

 pubescent, and the enclosure of the metathorax (except the broad shining 

 rim) entirely covered with strong vermiform rugae. The clypeus (except 

 its upper margin) is wholly purplish-black, with very large, sparse 

 ■punctures, and no testaceous border ; the supraclypeal area is more or less 

 brassy. The knees, apices of tibiae, and tarsi more or less, are ferruginous. 

 Antennae black, flagellum dark brownish beneath. Mesothorax strongly 

 and rather closely punctured on a microscopically tessellate surface. First 

 abdominal segment smooth, with sparse, very minute punctures ; second, 

 with equally small but rather closer punctures, and more or less trans- 

 versely striatulate basally. Hind spur of hind tibia with few, large, teeth. 

 Belongs to Robertson's group Chloralidus.
