120 THE CANADIAN ENTOMOLOGIST. 



was considered a Rocky Mountain species, but lately specimens have 

 been taken in Iowa, Illinois, and Indiana. 



Another question is why the form Fabricii should appear before 

 Umbrosa and then later on both forms appear at the same time? 



The broods of Interrogationis seem very irregular as to time of 

 appearance, but there are at least two annual broods here. 



A NEW CCELIOXYS FROM NEW MEXICO. 



BV T. D. A. COCKERELL, MESILLA, N. M. 



Ccelioxys menthce, n. sp. — ,:f . Length 9 V3 mm., black with the legs 

 and base of abdomen ferruginous. Pubescence scanty, dull white, rather 

 dense and tinged with ochraceous on face. Head rather large ; 

 vertex shining, with large, well-separated punctures ; mandibles bifid at 

 ends, ferruginous except tips and extreme base ; antennas black, flagellum 

 faintly rufescent beneath towards the end ; mesothorax shining, with 

 extremely large, well-separated punctures ; a band of dull white pubes- 

 cence at base of scutellum and a patch above base of wings ; scutellum 

 shining and sparsely punctured, without any trace of a keel, rounded 

 behind, with a very small tubercle at the middle (representing the median 

 tooth of aperta, etc.), lateral teeth large, flattened and rounded at tips ; 

 enclosure of metathorax distinct, very finely granular, with a basal series 

 of large pits ; teguls apricot colour ; wings dusky hyaline, the apical 

 margin broadly smoky, nervures piceous, stigma fuscous, marginal cell 

 more produced at tip than in altilis \ coxae more or less darkened, legs 

 otherwise entirely bright ferruginous, with the pubescence extremely 

 scanty ; abdomen shining, segments 2-5 with transverse sublateral 

 grooves ; punctures sparse, largest and densest at sides, rather small and 

 numerous on dorsum of first segment, absent on dorsal middle of 

 segments 2-5, except for an apical row and on 2 an imperfect basal one ; 

 sixth segment with sparse minute punctures. Hair-bands very narrow and 

 interrupted dorsally, so as to be inconspicuous. First segment except 

 the extreme base entirely ferruginous ; second and third segments, and 

 fourth more or less, ferruginous at sides ; venter ferruginous except apex. 

 Apex with six teeth, of the terminal ones the lower are the longer. 



Hab. — Deming, N. M., at flowers of garden mint in Mrs. Bristol's 

 garden, July 9, 1896. (Ckll. B. 45.) Very distinct by the sparsely 

 punctured (in parts impunctate) abdomen with its rufous first segment. 

 Nearest, perhaps, to C. texana, Cr. 



There is a Ccelioxys taken by Prof Townsend on the Gila R. in 

 numbers, which I could not definitely identify. A specimen sent to Mr. 

 Fox comes back marked " near mcesta." Very possibly the species is 

 new, but I do not at present care to give it a name, as there are several 

 closely allied forms which I have not seen, and it may be one of them. 



Mailed May 1st, 1897.
