tween the coxae. Prosternum abruptly deeply sulcate on the apical con- 

 striction, with distinct delimiting lateral ridges; convexly prominent each 

 side before the coxae; the median sulcus becoming gradually evanescent 

 posteriorly so that the prosternum is only very slightly concave between 

 the coxae. Ventral segments 2, 3 and 4 abruptly declivous on hind mar- 

 gin, the segment following each commencing on a lower plane. 



Fore coxae separated by about half their width, the others more widely 

 distant. Tibiae carinate externally; middle and hind tibiae slightly ex- 

 panded at tip, the latter pair with a small tooth on the inner side at apex, 

 the others strongly mucronate. Tarsi long and slender, densely pubescent 

 beneath; subequal to the tibiae; third joint bilobed; last joint elongate, 

 nearly as long as the remainder, bearing two claws which are connate at 

 basal third, the suture evident. Length 3 mm., width 1.8 mm. 



The specimen described above is a female taken at Marfa, 

 Texas, July 12. Mr. Wenzel has a male from Davis Moun- 

 tains, Texas, which differs in the shorter, stouter, more 

 coarsely punctured beak, the antennae inserted at the middle, 

 where there is a very slight lateral enlargement; the front 

 coxae more widely separated; the first ventral segment some- 

 what concave at middle; and the pronotum more coarsely 

 punctured. 



Centrinoides is a more squamose species than any pre- 

 viously described Zygobaris and may possibly not be congen- 

 eric with nitens Lee. and xanthoxyli Pierce, which I have not 

 seen. 



The type of this species as well as the types of the other 

 new species described in this paper are in my cabinet. 



An Appreciation (Diptera). 



The work of Dr. Alvah Peterson on The Headcapsule and Month-parts 

 of Diptera, in the Illinois Biological Monographs, vol. Hi, No. 2, has re- 

 ceived an appreciative notice from Or. A. I). Imms in the Entomolo- 

 gist's Monthly Magazine (London) for May, 1920. 



Sad but Familiar. 



A recent number of the Bulletin of the Entomological Society <>l I ; ram<- 

 (1920, No. 4) announces that, as a measure of economy, it has been de- 

 cided to reduce the covers to four pages and to replace the table of con- 

 tents with advertisements; that in the future the Society can only accept 

 line drawings; photographs and drawings necessitating half-tones will be 

 reproduced only at the expense of the authors.
