iog iu the dry specimens of this species. It consists, as already observed, 

 of three horny, slender styles, connate at the basis, separate and some- 

 what club-shaped at the tip. 



Gen. XI. PHALACROCERA.® 

 [This is another portion of my manuscript which was left unfinished, 

 as I was expecting Mr. Loew's opinion about the location in this genus 

 of the following species. It agrees with Phalacrocera Schiner, (1. c. II, 

 p. 561) in all respects, with the exception that in the European P. 

 nudicornis the first longitudinal vein takes the usual course and is not 

 incurved towards the second, as is the case with P. tipulina and with 

 the other Limnobina cylindrotomseformia. This difference, if it is a 

 constant one, and if it really exists as stated, would be important. Under 

 such circumstances, the location of the following species in this genus 

 should be considered as only provisional. The antennae of Phalacro- 

 cera nudicornis, rather incompletely described iu Dr. Schiuer's work, 

 are exactly like those of P. tipulina, as I had occasion to ascertain 

 through the kindness of Dr., Schiner himself.] 



P. tipulina n. sp. %, — Fuscescens, capite et thorace supra obscure einereis, 

 hoc obsolete vittato, pleuris canis ; antennarum articulis subcylindricis, elon- 

 gatis ; cellulis posterioribus quatuor. 



Brownish; head and thorax dark cinereous above, the latter with obsolete 

 stripes; antenna; with subcylindrical, elongated joints ; four posterior cells. 



Long. corp. 0.55. 



Head considerably narrowed posteriorly, blackish above, with a yellowish- 

 cinereous bloom and a small reddish spot in the middle of the vertex, posteri- 

 orly; the under side of the head is brownish: proboscis brownish-yellow; 

 palpi brown; the antennae, if extended backwards, would reach the end of the 

 second abdominal segment ; they are dark brown or black ; the first half of the 

 first joint and the basis of the third are reddish ; first joint cylindrical, elon- 

 gated : second short; the third and the following joints are elongated, cylin- 

 drical, somewhat incrassated on their anterior half and with the verticils 

 inserted on that incrassation ; the flagellum is clothed on both sides with 

 a very short and soft pubescence : (the structure of the antennas is remarkably 

 like that of some Tipulae). Thorax above with a yellowish-cinereous bloom, 

 concealing the blackish ground color; the latter is more apparent in the place 

 of the usual stripes, whereas tin.; cinereous bloom is more dense in the some- 

 what impressed intervals between the stripes; pectus black between the first 

 and the second pairs of coxae anil this black color extended upwards, in the 

 shape of a stripe over the pleurae : a black spot near the basis of the halteres ; 

 the remaining portion of the pleurae brownish-yellow; the whole of the pleurae 

 are covered with a dense hoary bloom, so that their black portions are visible 

 in a certain light only; collare rather broad, brownish; scutellum and meta- 

 notum brownish-yellow, the latter with a yellowish, shining reflection: hal- 

 teres dusky ; coxae yellowish, with a hoary bloom : femora tawny, yellowish at
