36S T. D. A. Cockerell — Arthropods in Burmese Anther. 



width of second posterior cell in middle 80, and at end 60; depth 

 of first posterior cell at vertical level of end of sulDmaroinal 96 : 

 apex of first basal cell apicad of apex of anal 76 ; width of ante- 

 rior part of thorax about 160 : length of halteres 21:0 (the knob 

 being 12S; : anterior femnr about 240; autennal arista about 



Burmese amber, from H. C. J. Swinhoe. On the same slab 

 as the type of ElectrofcBnxis but on the other side, close to the 

 thickest part of margin, 32™™ from type of Electrohisiura 

 and nearly 6™™ from margin. This is a remarkable little 

 fly, suggesting the Tachydromiinae in some of its characters, 

 but excluded from that group by the possession of an anal cell. 



COLEOPTEEA. 



Cryj'jhalttes new genus (Tpidse). 



Small cylindrical beetles of the subfamily Cryphalinse ; thorax 

 and elytra strongly tuberculate, and with small clavate hairs ; 

 elytra rounded posteriorly ; head, seen from above, not con- 

 cealed ; anterior femora very stout ; anterior tibiae stout, the 

 outer margin strongly convex, the inner with small clavate 

 spines from base to apex (these tibiae are seen in very oblique 

 view, so the figure may not be quite correct as to proportions); 

 hind tibi^ stout, subcuneiform, with seven spines (not clavate) 

 on inner side near apex ; on inner side of tibiae at apex, and of 

 small tarsal joints, are long flattened hairs ; small joints of 

 tarsi short and thick, third joint simple, fourth so small as to 

 be invisible, so that the tarsi seem four-jointed ; fifth joint 

 long and stout, fully as long as the others taken together, with 

 large simple claws. Unfortunately the antennae cannot be 

 seen. Type the following. 



CrypTtalites ruyosissraus new species. 



Black. The following measurements are in microns : length 

 of thorax dorsally, 800 ; length of elytra, 1600 ; length of last 

 joint of hind tarsus, 96, and of its claws, 80. 



The flattened tarsal hairs are homologous with the remark- 

 able fimbriate hairs figured by Hopkins in Ptilojyodius. The 

 spines of hind tibiae are also essentially as in female Ftilopo- 

 dais^ a genus from the Philippine Islands. The rugose sculp- 

 ture is wholly unlike that of Ptilopydius.

 the same large piece as that containing the tyj^e of Electro- 

 feenus.
